1PI 6605099076517Pascopyrum smithii (Rydb.) Barkworth & D. R. Dewey Utah, United StatesW62010DEVELOPED12/2009CultivarRecovery , western wheatgrass, (Pascopyrum smithii [Rydb.] A. Love) was released in December 2009 by the USDA-ARS, the U.S. Army Corps of Engineers-Engineer Research and Development Center, and the USDA-NRCS. Recovery was developed for reseeding rangelands following severe disturbance, frequent fires, and soil erosion with selection emphasis on improved and faster seedling establishment. Recovery was evaluated as TC3, TC-Rich, Army WWG, SERDP WWG, and NRCS-9076517, and was developed as a synthetic cultivar using two cycles of recurrent selection for plant vigor, seed yield, and rate of seedling emergence from a deep planting depth. In field evaluations, Recovery had increased frequency of seedlings during the establishment year, when averaged across eight locations, than other common western wheatgrasses. Recovery continued to have superior stand until 4 to 6 years after planting, when due to their rhizomatous nature, all the western wheatgrasses had similar stand frequencies. Recovery western wheatgrass provides land managers a new western wheatgrass cultivar with rapid establishment for use in areas that are frequently disturbed such as military training lands. The use of Recovery will help reduce soil erosion and weed invasion following such disturbances.1855264PI 660509

Downs. Joint release of New Mexico and Colorado Agricultural Experiment Station and Soil Conservation Service, U.S. Department of Agriculture.

Western wheatgrass is a cool season, rhizomatous, sod-forming, perennial grass. Culms are erect, 30-60 cm tall with creeping rhizomes; blades are firm, stiff, mostly flat when fresh, involute on drying, strongly nerved, scabrous, to 4 mm wide and tapering to a sharp point. Flowering spikes are erect, 7-15cm long; spikelets are closely inbricate, 6-10 flowered, 1-2 cm long; glumes are rigid, tapering to a short awn, and are faintly nerved. Entire plant is usually glaucous and gray-green in color.
