Deseret
1. Kayseri alfalfa was developed by two generations of phenotypic recurrent selection for stem nematode resistance in an introduction from Turkey (P.I. 279958). Approximately 150 resistant plants were selected each generation and interpollinated by leaf cutter bees in a cage.
2. The variety was developed for the irrigated valleys of Utah and similar areas where stem nematodes and bacterial wilt are problems. It is expected to replace Lahontan in Central and Northern Utah.
3. Flower color is purple with a large range in color intensity from nearly white to dark purple. Other characteristics include resistance to bacterial wilt, stem nematodes, and lodging. Deseret alfalfa is tall and erect with a growth habit and yield similar to DuPuits, but with less saponin.
4. Seed increase shall be limited to the Breeder, Foundation, Registered and Certified classes. The production of Foundation and Registered seed shall be restricted to Idaho, Oregon, and Washington, and the Northern one-half of Utah and Nevada.
5. Certified seed will be available in 1976 probably.
6. Protection under the Plant Variety Protection Act is being considered.
