Intrada is a hard white winter wheat variety released by the Oklahoma Agricultural Experiment Station in 2000. Intrada is a medium-late maturing (similar to 2174), awned, semidwarf variety, similar to Chisholm and 2174 in height and intermediate (similar to Custer) in timing of first hollow stem stage. Test weight has been outstanding, consistently exceeding 2174, 2137, Custer, and Jagger by 0.5 to 4 lb/bu. Grain yields are competitive with widely grown hard red winter wheat varieties in Oklahoma and the best white wheat varieties available for production (Table 1). Coleoptile length is short, and seed size is relatively uniform but slightly smaller than average. Forage yields have been intermediate (Table 2). Intrada has intermediate protein levels, medium-short mixing time, and good mixing tolerance. Baking evaluations for Intrada have been good to excellent. Disease resistance is acceptable for northwestern Oklahoma with resistance to soilborne mosaic virus with a low frequency of susceptible plants, resistance to stem rust, moderate resistance to leaf rust, and moderate susceptibility to tan spot and powdery mildew. Intrada is susceptible to Russian wheat aphid, greenbug, and Hessian fly, and has intermediate tolerance to low-pH soils. Intrada is best adapted to dryland production conditions in northwestern Oklahoma, including the panhandle (see map on front). Susceptibility to pre-harvest sprouting prevents us from encouraging its production in the remainder of Oklahoma. Lodging may occur under conditions of high straw production or under irrigation. It recovers very well after grazing in a dual-purpose system. GENETIC BACKGROUND The pedigree of Intrada is Rio Blanco/TAM 200. The original cross was made by Joe Martin, wheat breeder for KSU, Hayes. Dr. Carver made the final selection and purification. Partial financial support for the development of Intrada came from the Oklahoma Wheat Commission and the Oklahoma Wheat Research Foundation. Oklahoma State University, in compliance with Title VI and VII of the Civil Rights Act of 1964, Executive Order 11246 as amended, Title IX of the Education Amendments of 1972, Americans with Disabilities Act of 1990, and other federal laws and regulations, does not discriminate on the basis of race, color, national origin, sex, age, religion, disability, or status as a veteran in any of its policies, practices or procedures.
