Comet
1. Comet is a synthetic variety with 464 parent clones. Parent clones trace to 22 populations screened for resistance to Phytophthora root rot, anthracnose, bacterial wilt, Fusarium wilt and Verticillium wilt using phenotypic recurrent selection. Parentage traces predominately in order of contribution to Endure, Apollo II, Apollo, Anchor, Trident, Saranac AR, Olympic and Atlas. Approximate germplasm source contributions are: M. falcata (10%), Ladak (8%), M. varia (22%), Turkistan (14%), Flemish (40%), Chilean (3%), and Peruvian (3%).
2. Comet is intended for use in the North Central U.S. for hay, haylage, greenchop or dehy production. It has been tested in Iowa, Idaho, Wisconsin and Pennsylvania.
3. Fall dormancy is similar to Ranger. Flower color is approximately 72% purple and 28% variegated with a trace of white, yellow and cream.
4. Comet has high resistance to bacterial wilt, resistance to Fusarium wilt, Phytophthora root rot and Verticillium wilt, and moderate resistance to anthracnose. Reaction to stem nematode, pea aphid, blue alfalfa aphid and spotted alfalfa aphid is not adequately tested.
5. Seed increase is limited to one generation each of breeder, foundation, and certified classes. Certified seed may be produced from either breeder or foundation class. A 2, 3 and 6 year stand life is permitted on fields producing breeder, foundation and certified classes respectively. Foundation seed production is limited to the Pacific Northwest.
6. Certified seed will be available in 1989.
7. Plant Variety Protection will not be applied for.
