Interpretive Summary: The hard red winter wheat (HRW) cultivar ‘TAM 305’ was developed and released by Texas A&M AgriLife Research in 2012. TAM 305 was derived from the cross TX97V3006/TX98V6239. TAM 305 was released for its leaf, stripe, and stem rust resistance and also because of its excellent grain yield in the Blacklands and South Texas. Comparisons to the HRW quality targets showed that TAM 305 has average milling yield, very good wheat and flour protein, minimal mixing time, excellent water absorption and loaf volume, but below average mixing tolerance. Authorized seed classes of TAM 305 are Breeder, Foundation, Registered, and Certified. TAM 305 has been submitted for U.S. Plant Variety Protection with the certification option.

Technical Abstract: Leaf and stripe rusts (cause by Puccinia triticina Erikss. and Puccinia striiformis Westend. f. sp. tritici Erikss., respectively) are major disease problems in South Texas, Rolling Plains, and the Blacklands area of the state where hard red winter wheat (HRW; Triticum aestivum L.) is a major crop and wheat producers in these areas require rust-resistant cultivars. A significant breeding objective in South Texas is to develop HRW cultivars with robust resistance to both rust pathogens. Among these HRW cultivars is ‘TAM 305’, which was developed and released by Texas A&M AgriLife Research in 2012. TAM 305 was derived from the cross TX97V3006/TX98V6239. The original cross, designated X00VC230, was made at College Station, TX in 1999. TAM 305 was released not only for its leaf, stripe, and stem rust (caused by Puccinia graminis f.sp. tritici) resistance but also because of its excellent grain yield in the Blacklands and South Texas. Milling and baking quality characteristics of TAM 305 were rated by the USDA/ARS-Hard Winter Wheat Quality Laboratory in Manhattan, KS. Comparisons to the HRW quality targets showed that TAM 305 has average milling yield, very good wheat and flour protein, minimal mixing time, excellent water absorption and loaf volume, but below average mixing tolerance. Texas plays a critical role in the development and spread of wheat leaf, stripe, and stem rust throughout much of North America and serves as one of the main contributors to the Puccinia pathway. Texas is one of the only areas in the US where these fungal pathogens overwinter and increase inoculum. If not properly controlled, this reservoir of inoculum is carried north by wind as the season progresses and can result in rust epidemics that negatively impact wheat production for much of the US. Texas A&M AgriLife breeding program in south, central, and northeast Texas has undertaken an aggressive approach to develop HRW cultivars, such as TAM 305, with robust resistance to the three rust types. TAM 305 HRW was developed and released in 2012 by Texas A&M AgriLife Research to target growers in South Texas, Rolling Plains, and the Blacklands areas where high yield, excellent grain volume weight, good baking quality and resistance to leaf and stripe rusts are sought. Authorized seed classes of TAM 305 are Breeder, Foundation, Registered, and Certified. TAM 305 has been submitted for U.S. Plant Variety Protection with the certification option.
