PERFORMANCE OF CORN HYBRIDS IN 1981l/

Charles R. Grave~/

The 1982 medium-season state corn hybrid tests were conducted at seven

locations, and full-season and early-maturing at four locations. No data are

reported for the medium-season test at Milan due to damage from a severe flood.

The tests at Ames Plantation, Jackson and Martin were harvested with a picker-sheller.

All other tests were harvested by hand. The growing season was good at most

locations in 1982. Spring Hill and Greeneville yields were reduced due to dry

weather during the growing season.

The leading hybrids in 1982 in the medium-season test were Pioneer brand 3147

(afull-season hybrid included as a check), Pioneer brand 3320, DeKalb 28012,

Pioneer brand 3184, DeKalb EX7979 and McCurdy 8150.

The leading hybrids in the full-season test were Pioneer brand 3165, Pioneer

brand 3160, DeKalb 29014, Pioneer brand 3147, McCurdy 80-72 and Funk G-4740.

The leading hybrids in the early-maturing test were McCurdy 81-82, McCurdy

84aa,Pioneer brand 3358, Pioneer grand 3389, DeKalb 28035 and O's Gold 2570.

McCurdy 81-82 and McCurdy 84aa had the highest grain moisture at harvest and should

Mve been evaluated in the medium season tests.

The highest yielding varieties evaluated under virus conditions were Pioneer

brand3160, Pioneer brand 3147, DeKalb XL72BB, FFR 848C, DeKalb 28012 and FFR 955C.

The grain of hybrids grown at Knoxville is being analyzed for crude protein

bythe UT forage testing lab in Nashville. These data will be reported in a later

publication.

Y These results will be included in the 1982 Bulletin, "Performance of FieldCrop Varieties", which will be available in 1983.
