EXPERIMENTS IN 22S

Some recordsmiddot are broken every year The 1952 ~ropmiddot year p~vided its smre bull

The southwest experienced a drought of unusual severity whereas Kansas and ~ ~ ~

Nebraska produced their largest wheat crops and Oklahona equslled any previous

year Rust threatened but did not damage the wheat much if any thanks to an

extended dry hot and windy period early in June The crop ripened earli~middot~1Jan

normal in nearly all areas especially in the central and northwestern districts

Some of the loss caused by 1951 floods Was repaid by the good crop produced in

part because of high subsoil moisture storage

Investigational work Was conducted at an efficient and accelerated rate in

1952 New lines of inquiry or greatly increased programs w~re establis]ed1n

several states from state federal and private funds on wheat insects mosaic

and rust and to Bomeextent on other problems This 1s very encouragingand

results from these projects will be helpful to theunderstanding and perhaps

solution of many wheat questions

middot This volume summarizes the data on wheat variety tests but does not give

thefUll scope of these and relat~dfundamental studies It is intended that

this report will be of value to all workers with wheat in the regionby~rovid1ng ~

local and regional results with old and new varieties

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

Yogo Newturk and Cheyenne were highest in yield at Moccasin Montana in 1952 All test weights were good COlllBnche suffered Bom~ loss of stand due to winterkilling and gave a poor yield Yogo and Irarmont are justifiably popular in this area beC8Wle of their long record of relatively good performance

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

Yogo Newturk and Cheyenne were highest in yield at Moccasin Montana in 1952 All test weights were good COlllBnche suffered Bom~ loss of stand due to winterkilling and gave a poor yield Yogo and Irarmont are justifiably popular in this area beC8Wle of their long record of relatively good performance

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

Yogo Newturk and Cheyenne were highest in yield at Moccasin Montana in 1952 All test weights were good COlllBnche suffered Bom~ loss of stand due to winterkilling and gave a poor yield Yogo and Irarmont are justifiably popular in this area beC8Wle of their long record of relatively good performance

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

Yogo Newturk and Cheyenne were highest in yield at Moccasin Montana in 1952 All test weights were good COlllBnche suffered Bom~ loss of stand due to winterkilling and gave a poor yield Yogo and Irarmont are justifiably popular in this area beC8Wle of their long record of relatively good performance

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

DATA FROM TEE nlSEftSE NUlSERIES

The uniform bunt nursery was grown at six stations in 1952 A seIJarate reIJort on this test has been prepared which is available for cooIJerators and other intershyested persons

The uniform rust nursery data likewise will appear as a separate reIJort

DA TA FROM THE QUALITY LABORATORY

Grain harvested from the uniform plots uniform yield nursery and uniform winterhardiness nursery along with tha~ from promising new strains of local intershyest was sent by cooperators to the Federal Hard Wheat Quality Laboratory for milling and baking studies Results on these samples will appear in a separate reIJort preshypared by laboratory workers

Kiowa Triumph Pawnee and Ponca wereb13stat Colbybull KioWa pas about the best all around record of varieties tested at this station Sus6eptLbility tomiddot loose ~inut J~~~ ~~orf~ult

At Akron Colorado late wrieties were generally lower in yieid tban earlyhnd mid-early ones In view of the drought in this area it is remarkable to note that five varieties exceeded 20 bushels to the acre

At Lincoln Nebraska Pawnee and Red Chief had the highest yields Pawnee has the best long-time record later varieties generally ranked far down the list Leaf rust was heavy this year but came in too late to do much damage Shattering by two varieties and lodging by several detracted from their appearance

Beat yields at North Pla tte were made by three unnamed selections and Pawnee C I 12711 has a nne two-year record Nebred has the best all8round long record

At Alliance Nebraska two unnamed wheats Sioux and Comanche yielded over 39 bushels to the acre C r 12523 and Sioux have the best period averages stem rust threatened to do damage but came too late in 1952

In the Brookings South ISkota test yields ranged from 328 to Z87 bushels per acre Pawnee was the only variety failing to survive the winter with a full stand Stem rust was moderately heavy on alJ varieties C I 12704 has the highest 4-year a verage yield

At Waseca Minnesota selection 2827 outyielded all varieties but showed weak straw and high susceptibility to rust The rust caused little or no shriveling of the grain Minter continues to perform about as well as any wheat at this station

Yields at st Paul Minnesota were unaffected by differential winterkilling Minter was highest in yield Considerable infection from rust occurred C r 12704 has the highest 4-year average yield

Lower survival was noted for Iohardi at Grand Repids Minnesota Minter was the highest yielding entry this year and appears to be the best variety in terms of the period average yields availabJe

At Sheridan Cheyenne and Iranred were highest in yield this year and have the best long-time average

At Hevre Montana the wheat headed and ripened much earlier than usual Drought was the principal factor depressing yields Yogo was midway in rank in 1952 but conshytinues to show a high average yield C I 12108 has shown promise in 10 years of testing

Pawnee and Comanche were 5 to 7 bushels higher in yield tban other varieties at Ames Iowa Lodging was excessive straw was long and weight per bUshel Was low All varieties have period averages 10 to 26 above KDarkof

Yogo Newturk and Cheyenne were highest in yield at Moccasin Montana in 1952 All test weights were good COlllBnche suffered Bom~ loss of stand due to winterkilling and gave a poor yield Yogo and Irarmont are justifiably popular in this area beC8Wle of their long record of relatively good performance

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations

STANDARD ERRORS

Standard errors have been calculated on the yield data for the current year A summary of these is shown in table 2 together with the number of plots and avershyage yields at each station A footnote indicates where nursery plots were used in place of field plots

The analysis of variance was used on the data at each station The square root of the mean square due to error or the standard deviation was divid~d by the square root of the number of replications of each variety to obtainthe standard error of the mean The standard error of a Qiff13rence ibetweenanytwo variety means ~s obtained by mUltiplying the standard error of a mean by the square foot of 2 Error expressed as a percentage of the standard devie tion is given also These statistics have considerable practical value to the agronomist even though complete random arrangement of plots was not followed at all stations

SUMMARY OF PLOT DATA

Summaries of yield data for 1952 and the recent two-year period appear in the sections which follow along with an average of other agronomic da t8 for 1952

Yields by Districts

Only four varieties were grown uniformly in the northeastern district Results are given in tables 7 and 8 with Minter best in both comparisons and Iohardi lowest as a result of rather consistent low yields in 1952

In tables 9 and 10 are the yields rnade by varieties grown in the northwestern district Yogo end Karmont continue to be about the best varietiesin the tests bull

Summary of Agronomic Data bull

Insofar as the same kind of note was recorded on a series of varieties in a district such data were averaged and bavebeenplaceci in tables 11 12 13 and 14 m all cases the vadeties are given irrdeclining order of weight per bushel Red Chief and Early Blackhull were heaviest in the southern district Tenwarq was the lightest Maturity rank was about as usual with Triumph earliest and Kb8rkof latest Plant height varied from 33 to 37 inches with Red Chief tallest

Red Chief in the central district was tallest stiffest and had the heaviest test weight Ponca was distinctly more resistant to leaf rust

In the northeastern districtTohard was heaviest iin weight per bush~l and earliest C I 12704 was slightly shorter than the others and Minter was slightly lowest in stem rust and loaging

Only three traits were notampd in the northwestern uniform trial~ as shown in table 14 bull

One test in New Mexico at Clovis was almost a failure from drought and was furshyther depleted by birds near harvest time Such low yields are of doubtfUl value in a single year The two-year averages give the Blackhull wheats some of the top rankshying positions although Pawnee ranks high also

Oklahoma had three tests At stillwater leaf rust broke out late to low readshyings on susceptible varieties All varieties exceeded 60 pounds to th~ bushel C I 12709 12515 and Stafford yielded over 40 bushels to the acre C I Nos 12517 12709 and 12515 have the highest period averages At Cherokee the yields weregoltgtd also stem and leaf rust lodging and Septoria (mainly on c r 12716) were evident C I 12702 C I 12517 Stafford and Comanche had the best yields These except Stafford have good period averages In the Woodward test weights per bushel exshyceeded 60 pounds Yields above 32 bushels to the acre were mdeby C I Nos 12515

bull 12702 12709 and 12710 Best four-year averages have been mde by C r 12517 and C r 12515

Three tests were in Kansas Shattering at Manhattan affected the yields of several varieties Even so high yields and excellent test weights were recorded Triumph Early Blackhull C r 12515 and C Ie 12517 were the highest producers Two-year averages favor C r 12517 although several have good records also Earlishyness at Hays tended to overshadow other factors Good yields were recorded for Triumph C I 12525 Early Blackhull Pawnee and others bull The be~t two-year record has been made by C I 12517 In the Colby test Triumph C I 12715 and C I 12711 were high in yield Two-year records made by C I 12515 and C I 12517 are imshypressive

Two tests in Colorado were harvested whereas a third was lost from hail Severe drought at Akron reduced yields but C I 12715 produced 182 bushels to the acre C I 12517 has the best two-year average At Hesperus C I 12702 and C I 12515 had the highest yields and the latterwith C I 12406 had the best three-year averages

At Ames Iowa severe leaf rust was noted and much lodging Yields of Triumph Blue Jacket C I 12715 andmiddotC I 12406 were highest Three-year averages favor Triumph Blue Jacket C I 12517 and Pawnee

Among the three tests in Nebraska C I 12711 was highest in yield at North Platte and ranked second and seventh at Lincoln and Alliance C I 12515 was highest at Lincoln and lowest at Alliance Different survivals at the latter station were recorded Hessian fly and leaf rust at Lincoln and stem rust at Alliance were added hazards this year Pawnee C I 12517 and C I 12406 rank first respecshytively at the three Nebraska stations

SUMMARy OF AGRONOMIC DATA

Data other than yield have been averaged and appear in table 19 Varieties are in order of declining average weight per bushel It is obvious that Blue Jacket Early Blackhull and Quivira Hybrid were heaviest at the 14 stations C 1 12710 averaged lightest There is a close relation from year to year in the rank of varieties for this character Maturity was checked at numerous stations and accurshya tely ranks the varieties for earliness Plant height ranged from 33 to 41 inches Lodging at four stations showed that C I 12715 C I 12716 and Pawnee stood best and that nine entries lodged more tban Kharkof Leaf rust at six stations points out the good resistance of the Sinvalocho Marquillo and Hard Feder~tion derivashytives stem rust at two stations was light and inconclusive

UNIFORM WIN~RDnmss NURSERY

As in previous y~~rs two unifQrm bard1ness nurseries ware maiita1nedbull The supplementary unit conteins new selections of interest to workers in al1 parts of the region It was amiddotsingle-row nursery planted in duplicate series in 1951-52 at Alliance Akron Brookings stmiddot Paul Moccasin and Dickinson Usable dilta -this year were obtained at all stations except Akron and Dickinson These were summarshyized and sent out before harvest to -breeders concerned with the entries in the test The four-station a verage ~urvival for Kbarkof Turkey and Tenmarq were 725 635 and 618 percent respect~vely Among the 127 tested 51 exceeded the average for Tenmarq and 10 surpassed Kharkof bull One entry killed completely at all etations As groups the wheat x rye s~lections and the Yogo x M~nter bulks had the highest _ average survival shy

The uniform replicated nursery contains varieties of interest to workers in the more northern statesfor the most part In 1951-52 16 varieties were tested at nine stations Survi~ls appear in table 20 Minturki and Kharkof M C 22 pad the best survival Yogo usUally among the hardiest had thin stands at several stations and this may bave influenced results

The uniform nursery Was-harvested for yield at seven stations The data are summarized in table 2L Kharkof and Sioux averaged highest and C I 12517 owing to winterkilling at several stations yielded least Weights per bushel are shown for six stations in table 22 Iohardi was clearly the best in this respect Various other notes were taken on the varieties at some stations
