• 2008 Colorado wheat variety survey
• 2007 WQC entry characteristics– Background, status
– Agronomic
– Yield
– Quality
Medium to strongerdough mixing properties
CSU Wheat Breeding
2007 WQC Entries• 07-2401: Hatcher (check)
– High yielding across the High Plains (CO, KS, NE Panhandle)– Much improved dough mixing and bread baking quality
relative to TAM 107/Prairie Red and Akron/Ankor profiles
• 07-2402: CO03W239 - KS01-5539/CO99W165– Hard white Clearfield* wheat, dryland adapted, MR stripe rust,
MS pre-harvest sprouting– On increase with intent to release fall 2008
• 07-2403: CO03W054 - KS96HW94//Trego/CO960293– Hard white, dryland adapted, MR stripe rust, MR pre-harvest
sprouting, WSMV resistant, 2008 breeder seed increase
• 07-2404: CO02W237 - KS98HW519/KS96HW94– Hard white, dryland adapted, MS stripe rust, MR pre-
harvest sprouting, 2008 breeder seed increase
