Named Releases: ‘Bozoisky Select’ (Cultivar) Release in 1984 by the Logan, UT ARS. Selected for improved seedling vigor and forage yield. Has been very successful on many adapted sites in the west.
‘Bozoisky II’ (Cultivar) Released by the Logan, UT ARS. Selected for better seedling vigor, seed mass, seed yield, vegetative vigor, total dry matter yield, and response to drought. It is a 15 clone, broad based, synthetic release.
