GROWING OF CATCH CROPSYIELD AND QUALITY OF THE MAIN CROPHAS AN POSITIVE EFFECT ON5Our philosophy isThat growing of the catch crop

KLICK

Should have a positive effect on yield and quality of the main crop

GROWING OF CATCH CROPSYIELD AND QUALITY OF THE MAIN CROPEROSION-CONTROLORGANIC MATERIALSOIL STRUCTURENITROGEN, NUTRIENTSUSEFUL SOIL ORGANISMWATER HOLDING CAPACITY6This works on the one side by increasing the organic matter in the soilProviding erosion control and saving the good soil on the fieldFeeding the useful soil organism, which help to stabilize the soilsaving nitrogene in the upper soil against leaching and make some other nutrients (like Kalium and Magnesium) available for the main cropImproving soil structure and opening soil compaction

All this helps to increase the water holding capacity of the soil, which becomes more and more important. The climatical change brings longer periods of hot and dry conditions.

GROWING OF CATCH CROPSYIELD AND QUALITY OF THE MAIN CROPEROSION-CONTROLORGANIC MATERIALNON HOST / RESISTANCE e.g. nematodesSOIL STRUCTURENITROGEN, NUTRIENTSUSEFUL SOIL ORGANISMPEST CONTROL/PROMOTION OF PLANT HEALTHWATER HOLDING CAPACITY7On the other hand we have to evaluate the catch crop in its value toward plant diseases.A positive effect on the main crop we will find in the case, the catch crop is a non host or better has resistance against diseases of the main crop (like nematode resistance)

So the catch crop helps to control the pest and/or promots plant health.

GROWING OF CATCH CROPSYIELD AND QUALITY OF THE MAIN CROPEROSION-CONTROLORGANIC MATERIALNON HOST / RESISTANCE e.g. nematodesSOIL STRUCTURENITROGEN, NUTRIENTSUSEFUL SOIL ORGANISMPLANT BASED ACTIVE AGENTSPEST CONTROL/PROMOTION OF PLANT HEALTHISOTHIO-CYANATEWATER HOLDING CAPACITYBIOFUMIGATION8The third way of acting is a new idea:Using plant based active agents, produced by the catch crops,Like glucosinolates degrading into Iso thio cyanates to control mainly soil borne diseases.This technique is called biofumigation.BREEDING TARGETS - BASICSFAST COVERING OF THE SOIL suppression of weeds saving soil humidity by elimination unproductive evaporation

HEALTHY PLANT DEVELOPMENT security for different crop rotations fast and deep root system good uptake of free nutrients

Our basic breeding targets are fast covering of the soilThis helps to suppress the weeds, which are posible multiplicater of plant diseasesFast covering of the soil also prevents against unproductive evaporation and save soil humidity.

KLICKThe basic target for catch crops is a healthy plant development to have security for different crops in the rotation,But also to ensure a fast and deep root system for a good uptake of free nutrients.e9BREEDING TARGETS GROWING CONDITIONSSeed densitySowing timeSowing techniqueStraw managementFertilizerWater

Organic matter productionWinter hardiness

10We test our crops under different growing conditions.This involves testing the behaviour with different seeding densitiesThe influence of sowing time on plant developmentDo different sowing techniques (like the rotation sowing in Denmark) prefer special crops? Or the other way round: do some varieties dont like this technigue?We test different straw management systemsDifferent fertilizer strategiesBehaviour of the varieties with drought stress

Testing of organic matter production and evaluating the winter hardiness are standard tests for our breeding program.

BREEDING TARGETS CONTROLLING DISEASES

Beet cyst nematode Heterodera schachtii

FIRST RESISTANT VARIETY IN 1980 FROM P. H. PETERSEN

FIRST VARIETY WITH MORE THAN 90% NEMATODE REDUCTION

11Our particular emphasis is on breeding varieties to control diseases.

We started with resistance against beet cyst nematodes, Heterodera schachtii, where we were the first in breeding a nematode resistance variety in 1980.

We were also the first with a variety, which is able to reduce more than 90% of the beet cyst nematodes, the variety is COLONEL and many of our new varieties are now also able, to reduce more than 90 %.

BREEDING TARGETS CONTROLLING DISEASESstubby root nematodes (Trichodorus sp.)Transmitter of Tabacco rattle Virus (corky ring spot syndrome)

FODDER RADISH VARIETIES:SILETTA NOVA, BENTO, LUNETTA

WITH BCN RESISTANCE: COLONEL

12Against stubby root knot nematodes ( the group of Trichodorus), which is the transmitter of the Tabacco Rattle virus, which cause the corky ring spot syndrome in potato and also the pea early browing virus,We developped special varieties to reduce corky ring spot and help especially consumption potato grower to harvest quality.

Our varieties are Siletta Nova, Bento and Lunetta for potato growers,And COLONEL for growers, who also have problems with Beet Cyst nematodes. BREEDING TARGETS CONTROLLING DISEASESRoot knot nematodes Meloidogyne chitwoodi, M. fallax, M. hapla, M. incognita; M. javanica)

MULTI-RESISTANT VARIETIES:DEFENDER: M.c. and M.f.COMMODORE: M.h.BOSS: M.i. and M.j.CONTRA: M.c., M.f., M.i. M.j. and M.h.

13Another group of nematodes are the root knot nematodes, where ther exist several forms:Meloidogyne chitwoodi and Meloidogyne fallax, both quarantaine diseases in Europe, and difficult to handle, because they are multiplicating on any plant. And thus make them so starnge.Meloidogyne hapla a problem in ecological farming systems, because this nematode multiplicates on clover and rises big problems in carrots.Meloidogyne incognita and M. javanica are important problems in vegetable production areas of South Europe and Middle East.

The so called MULTI-RESISTANT VARIETIES against several nematodes are:DEFENDER: M.c. and M.f.COMMODORE: M.h.BOSS: M.i. and M.j.CONTRA: M.c., M.f., M.i. M.j. and M.h.

BREEDING TARGETS CONTROLLING DISEASESDitylenchus dipsaci - Stem nematode

Pratylenchus free living nematodes

Rhizoctonia solaniVerticillium ..

NEW TECHNIQUES: BIOFUMIGATION

14Further we work in our breeding program onResistance against Ditylenchus dipsaci a stem nematode, causing problems in sugar beets, potato and vegetablesFree living nematodes from the Pratylenchus group (this is an example of some new crop we are developping: on the picture you can see AVENA STRIGOSA, a whistle oat, where we select a variety with resistance against Pratylenchus penetrans)

We test aslo against fungi diseases like Rhizoctonia and Verticillium and

KLICKDevelop new methods to control diseases, like the biofumigation techniqueLAST BUT NOT LEAST: SEED QUALITYHighest quality seed, well above the minumum standard

15Last but not least

We do not only breed varieties which meet the farmers requirements as a seed producer we put great effort on quality seed, well above the minimum standard to satisfy the farmer in his ambition to have maximum returns and sustainable productivity.

CONCLUSION

all parts Have to be optimized and lead together to SUCCESS

for the Environmentand the farmer.

all parts:the quality of the varietiesthe quality of the seedthe growing system of the farmerthe the regional well informed advisorHave to fit together and to optimze their part to lead together to success.For the environment and for the farmer.
