Primus (pronounced PRY-mus) is a new barley developed cooperatively by the South Dakota Agricultural Experiment Station and the Crops Research Division, Agricultural Research Service, U. S. Department of Agriculture, and given final release in December 1966. It is a variety that combines earliness with high yield, high bushel weight, heat tolerance, drought resistance, and sufficient disease resistance or South Dakota conditions. Approximately 1,000 bushels of seed were released by the Foundation Seed Stocks Division, South Dakota State University, in spring 1967 to the South Dakota County Crop Improvement Associations for further increase.
