Cimarron VR
1. Cimarron VR is a synthetic alfalfa-variety selected from the Cimarron variety by phenotypic recurrent selection for resistance to Verticillium wilt. The germplasm sources of Cimarron VR are considered to be largely from Chilean and Flemish origins with estimates as follows: M. falcata 2%, Ladak 2%, M. varia 20%, Turkistan 10%, Flemish 26% and Chilean 40%.
2. Cimarron VR is intended for use as hay, haylage, greenchop, dehydration products in the Southern and Central Great Plains, the Central Cornbelt, the Middle Atlantic States and the South and Southeastern United States. It has been tested in North Carolina, Georgia, Pennsylvania, and Oklahoma.
3. Fall dormancy (fall growth) is similar to Dupuits. Flower color is 81% purple and 19% variegated, with a trace of cream.
4. Cimarron VR has high resistance to anthracnose, bacterial wilt, Fusarium wilt, the pea aphid, and the spotted alfalfa aphid; resistance to Verticillium wilt and moderate resistance to Phytophthora and to Aphanomyces root rot. Reaction to the blue alfalfa aphid and the stem nematode has not been tested.
5. Seed increase is on a limited generation basis with one generation each of breeder, foundation, and certified seed classes; i.e., breeder (Syn 1), foundation (Syn 2), certified (Syn 3). Breeder seed was produced under isolation in Apex, NC. Foundation and certified classes are produced by Great Plains Research Company, Inc. under contract with seed growers. Age of stand for seed production for breeder, foundation, and certified seed is 1, 2, and 6 years, respectively. Breeder and foundation seed stocks are maintained by Great Plains Research Company, Inc.
6. Certified seed will be marketed in 1990.
7. Application will be made for Plant Variety Protection under the Act. The certification option will not be requested.
