Wheat Breeders Work to Achieve Victory Over Biggest Threat

A problem that has plagued wheat growers for decades may be nothing but a distant memory in the future. Plant breeders have targeted the crop’s No. 1 enemy — fusarium head blight — with gusto. Many believe the disease will be all but eliminated a few decades from now. “I think by the time I retire, we should be at the point where almost all the varieties will have pretty good resistance by default,” said University of Illinois plant breeder Jessica Rutkoski. “That’s assuming we keep going in this direction and keep improving.” The fungal disease — commonly referred to as scab — slams growers with a one-two punch that reduces yields and diminishes quality. Infestation can reduce test weights and increase deoxynivalenol levels (usually referred to as DON) which results in vomitoxin.
