V5481
1. VS481 is a variety which was developed by strain crossing followed by phenotypic recurrent selection for resistance to anthracnose or spotted alfalfa aphid. Parentage traces to Florida 77, Jubilee, Cimarron, WL 318, and NCMP-1. Estimates of the major germplasm sources that constitute this variety are M. falcata (2%), M. varia (2%), Turkistan (4%), Flemish (47%), African (35%), and unknown (10%).
2. VS481 is intended for use in the Piedmont and Midsouth regions of the USA for hay, haylage, or dehy production. VS481 has been tested in Virginia, Georgia, and Alabama.
3. VS481 is a moderately dormant variety with fall dormancy similar to DuPuits. Flower color is approximately 85% purple, 12% variegated, 2% yellow, and 1% cream.
4. V5481 has high resistance to anthracnose, Fusarium wilt, and southern root-knot nematodes (Meloidogyne incognita races I and III); resistance to pea aphid and spotted alfalfa aphid; moderate resistance to Phytophthora root rot and bacterial wilt; and low resistance to Verticillium wilt. Reaction to stem nematode and blue alfalfa aphid are undetermined.
5. Seed increase is on a limited generation basis with one generation each of breeder, and up to two generations of foundation and certified seed classes. Breeder (Syn 1), foundation (Syn 2 or Syn 3), and certified (Syn 3 or Syn 4) classes will be recognized. Breeder seed (Syn 1) was produced in an isolated field near Woodland, CA in 1984. Sufficient foundation seed for the projected life of this variety will be maintained by Vista. Production of Syn 3 foundation seed requires consent of the breeder. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.
6. Certified seed will be available in 1990.
7. No decision has been made regarding Plant Variety Protection.
