CONTROL OF STRIPE RUSTS OF CEREAL CROPS

1. To conduct testing for identifying races and molecular genotypes of the wheat and barley stripe rust pathogens and determine distributions, frequencies, and dynamic changes of races and individual virulence factors of the pathogens in the United States. 2. To conduct experiments and analyses for identifying new sources and new genes of stripe rust resistance, developing molecular markers, and developing improved germplasm of wheat and barley for stripe rust resistance for more efficient use in breeding programs. 3. To participate in wheat and barley germplasm and breeding line screening for resistance to stripe rust and other diseases.
