'Hycrest II' crested wheatgrass (Agropyron cristatum L.) (Reg. No. CV-31, PI 653685) was released by the USDA-ARS and the Utah State Agricultural Experiment Station and was developed for reseeding disturbed rangelands dominated by annual weeds as a result of severe disturbance, frequent wild fires, and soil erosion. Hycrest II is one of the original parents to the cultivar Hycrest and originated by intercrossing 10 induced tetraploid plants of 'Fairway' crested wheatgrass. Selection emphasis in Hycrest II was on seedling establishment on disturbed rangelands. When planted at a rate of 1 pure live seed cm-1, Hycrest II had more seedlings per unit area during the establishment year than Hycrest at Blue Creek, UT, Green Canyon, UT, Mandan, ND, Miles City, MT, Dugway, UT, and Stone, ID. At Dugway, UT, Hycrest II had more seedlings per unit area than 'CD II' crested wheatgrass. Foundation seed of Hycrest II is available through the Utah Crop Improvement Association.
