Narrative
Don a diploid falcata alfalfa (Medicago sativa subsp falcata L.) developed by the Forage and Range Research Laboratory in Logan, Utah in cooperation with the Utah Agricultural Experiment Station, Utah State University. Recent interest in falcata alfalfa has been high due to its value for increasing the productivity of rangelands. Don was selected for persistence under harsh conditions, uniform yellow flower color, increased seed production and large stature plants. Don traces to PI20725, an original collection made by N.E. Hansen in the Don Province of Russia. Don was tested as AU021. Don is significantly more persistent than typical sativa type alfalfas and is meant for use in mixed plantings with grasses either in range or pasture situations typical of the Intermountain region of the Western U.S. In comparative trials, including irrigated and non-irrigated, where 25 to 50 percent mortality was observed on sativa alfalfas, Don showed no mortality. When used in mixtures the production advantage with tall fescue and meadow brome ranged from 10 to 32 percent. When grown with crested wheat grass on dry rangelands, similar production advantages are expected which will make rangelands more productive. Furthermore, when grown in mixtures with grasses, Don will not dominate; rather it has a low growth habit and stays well below the canopy of most cool season grasses.

Pedigree
Description:
Don was derived from the original PI20725. It under went three cycles of recurrent selection for uniform flower color, upright plants with increased size, persistence, and seed production. Selection cycles were completed in 1976 at Brookings, SD; 1978 at Utah State Univ. Bluecreek farm; 1984 and 1999 at Utah State Univ. Evans Farm.
