Abstract

The USDA-ARS announces the release of the meadow bromegrass [Bromus biebersteinii Roem. & Schult. (excluded)] cultivar ‘HighWest’ (Reg. no.

Selection emphasis in HighWest meadow bromegrass was on crude protein (CP), DMY regrowth, quality, and seedling emergence from a deep planting depth under irrigation. HighWest has been evaluated in Utah comparing it to meadow bromegrass cultivars ‘Cache’, ‘Arsenal’, ‘Regar’, ‘Admiral’, and ‘Armada’.
