HYPOTHESIS & OBJECTIVES:
Stripe rust is one of the most important diseases of wheat in the Pacific Northwest (PNW). The disease affects all classes and types of wheat and occurs in all agronomic zones. Without resistance, winter and spring wheat in the PNW can be infected. Stripe rust is most destructive in the high rainfall and irrigated zones.
Funding was granted to Dr. Chen who is working with University of Idaho wheat breeders to make the Idaho wheat germplasm resistant to the old and new races of stripe rust.
Recently these new races have been evolving so quickly, that testing all early generation breeding materials for this disease along with the other agronomic and quality parameters incorporated in each wheat seed, is more than one facility can adequately handle. With Chen’s help UI wheat breeders can increase breeding line evaluation and race monitoring work, areas that directly impact growers.
1) Monitor occurrence, distribution, and severity of rusts and determine population variation and epidemiology of wheat stripe rust.
2) Screen wheat germplasms and breeding lines for resistance to stripe, leaf, and stem rust; identify and create new germplasms for improving resistance to rusts especially stripe rust.
