Abstract
Four selected germplasms of bristlegrass (Setaria vulpiseta (Lam.) Roem. & Schult. and S. leucopila (Scribn. & Merr.) K. Schum. [Poaceae]) have been released for rangeland plantings and wildlife habitat enhancement plantings in the Rio Grande Plain of Texas. Catarina blend bristlegrass is a mix of 4 bristle-grass releases (Kika648 Germplasm, Kika819 Germplasm, Kika820 Germplasm, and Kika677 Germplasm) selected from an extensive evaluation at multiple sites in south Texas. Accessions included in the blend are increased in isolation and blended prior to sale in order to maintain the genetic integrity of each release. These germplasms represent the first commercially available release of bristlegrass that has been tested and is adapted to south Texas.
