Researchers at Kansas State University are using new techniques in analyzing plant genetics that have already discovered two genes that make wheat resistant to Russian wheat aphids.
By identifying genetic markers, the researchers can show breeders how to quickly identify whether a crossbred wheat variety has retained the aphid resistance gene. The find should greatly accelerate research into aphid-resistant wheat. Already the Kansas Agricultural Experimental Station has released a wheat variety resistant to the aphid as well as leaf and stem rust.
