Technical Abstract: TAM 304 wheat is a medium-early hard red winter wheat. It is a great dryland or semi-irrigated wheat. TAM 304 performs best under adequate rainfall, limited irrigation, or irrigation, but does not perform as well under extended drought. TAM 304 performs exceptionally well under foliar disease pressure, such as in Blacklands and South Central Texas. It has excellent leaf rust resistance, is moderately susceptible to stripe rust, and has resistance to the most prevalent stem rust race (TPMK). It appears to have a wide area of adaptation. Across multiple locations and 4 years, TAM 304 was one of the highest yielding entries in High Plains Irrigated, Rolling Plains, Blacklands, and South Central Texas. It was average yielding in High Plains Dryland trials. TAM 304 withstands grazing and can be used in a dual-purpose system. Forage production is similar to other currently grown wheat cultivars. TX01D3232 is an F4 derived line from the cross TX92U3060/TX91D6564 (=X95U104-P66). The cross was made during the winter of 1994-95. The pedigree of TX92U3060 is WO541A/W2440//W2407/’Arkan’ and the pedigree of TX91D6564 is TX85V1326/TX86D1312. The F3 generation was grown as a bulk population on the Texas Agricultural Experiment Station (TAES) farm at McGregor in 1998 (year of harvest). In the fall of 1998, seed of the F4 bulk was shared with the TAES wheat breeding programs of other parts of the state, including TAES Dallas. Random heads were harvested from the F4 population being grown at Dallas and these were planted as head-rows at the TAES-Prosper research farm in the fall of 1999. The line that became TX01D3232 was visually selected for its agronomic characteristics and was grown as a single plot in 2001 and in replicated trials thereafter.
