Why is this population important?
Rio Blanco is a semi-dwarf hard white winter wheat developed by Agripro. IDO444 is a tall stature hard red winter wheat from Idaho.
The population is segregating for bread quality traits (milling yield, dough rheology, protein concentration) and disease resistance to stripe rust (HTAP), leaf rust, snow mold, and dwarf bunt. We have phenotyped the population for stripe rust and dwarf bunt resistance. We will phenotype the population for milling yield and gluten strength during the CAPS grant.
Back-up population Coda/Brundage: Coda is a winter club wheat developed by the USDA-ARS Pullman with resistance to stripe rust and strawbreaker foot rot and excellent club quality, particularly as measured by sponge cake quality. Brundage soft white winter wheat was developed in the University of Idaho by R. Zemetra. It has some HTAP resistance to stripe rust but is primarily grown for its high yield, lodging resistance, and excellent soft wheat quality as measured by a sugar snap cookie. This population will be characterized for resistance to stripe rust and straw breaker foot rot. The Coda/Brundage population will also be phenotyped for soft wheat milling and baking quality.
