Interpretive Summary: 'Brawl CL Plus' is a new hard red winter wheat cultivar developed by the Colorado Agricultural Experiment Station and USDA and released August 2011. Brawl CL Plus was selected from the cross Teal 11A/'Above'//CO99314. Teal 11A is a hard red spring wheat line from BASF Corporation that carries a gene conferring tolerance to imidazolinone herbicides. 'Above' carries another gene conferring tolerance to the herbicides. CO99314 is an experimental line with the pedigree TX91V4931/'Halt'. Brawl CL Plus was selected as an F3:4 line, CO06052. It carries two genes for herbicide tolerance, is adapted to the production conditions in eastern Colorado, has moderate resistance to stripe rust, and good milling and bread baking quality attributes.

Technical Abstract: 'Brawl CL Plus' (PI 664255) hard red winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released August, 2011, through a marketing agreement with the Colorado Wheat Research Foundation. In addition to researchers at Colorado State University (CSU), USDA-ARS researchers at Manhattan, KS, St. Paul, MN, and Pullman, WA, participated in its development. Brawl CL Plus was selected from the cross Teal 11A/'Above'//CO99314 made in 2003 at Fort Collins, CO. Teal 11A is a proprietary hard red spring wheat germplasm line from BASF Corporation that carries a mutant allele at the Als2 locus (B genome) conferring tolerance to imidazolinone herbicides. Above (PI 631449) is a hard red winter wheat cultivar released by CSU in 2001 that carries a mutant allele at the Als1 locus (D genome) conferring tolerance to imidazolinone herbicides. CO99314 is an experimental line from CSU with the pedigree TX91V4931/'Halt' (PI 584505). Brawl CL Plus was selected as an F3:4 line in July, 2006, and assigned experimental line number CO06052. Brawl CL Plus was released because it carries two mutations for enhanced tolerance to imazamox herbicide, is adapted under non-irrigated and irrigated production conditions in eastern Colorado, confers moderate resistance to stripe rust (Puccinia striiformis f. sp. tritici), and has good milling and bread baking quality attributes.
