To introgress genes resistant to Russian wheat aphid, greenbug, and bird cherry oat aphid into adapted germplasm.
Cereal aphids, including Russian wheat aphid (RWA), greenbug (GB), and bird cherry oat aphid (BCOA), are serious pests of wheat, one of the most important crops in USA. ARS in Stillwater, OK, is focused on characterization and introgression of aphid-resistance genes into adapted germplasm with genomics-assisted selection. Our long-term goal is to breed high-yielding germplasm with good biotic and abiotic resistances. We will: 1) identify novel aphid resistance sources; 2) characterize traits of agronomic importance with molecular markers, including aphid resistance, disease resistance, drought resistance, yield and quality; 3) introgress important genes into elite cultivars with marker-assisted backcross; and 4) evaluate wheat breeding lines in multiple locations in Oklahoma.
