DS491 1. DS491 is a 5 clone synthetic variety. Parent plants were selected from disease screening evaluations. These parent plants were progeny tested for one or more of the following traits: forage yield, persistence, seed yield, resistance to Phytophthora root rot, anthracnose (Race 1) and leaf disease. Parent plants trace back to Sapphire, Nitro, Volo, Falcon and Monarch. The percent of germplasm sources are: Flemish(10), Chilean(13), Peruvian(31), Indian(20), and African(26). 2. D5491 is adapted and intended for use in the Southwestern Region of the United States. Where it has been tested are California, Wisconsin, Buenos Aires, Santa Fe Argentina. The states 3. D5491 is a non-dormant variety similar to Moapa 69 in fall dormancy. Flower color in the Syn. 2 generation is 90% purple, 10% variegated with trace amounts of cream, white and yellow. 4. D5491 has high resistance to Fusarium wilt, spotted alfalfa aphid, blue alfalfa aphid, northern root-knot nematode; resistance to Phytophthora root rot, bacterial wilt; moderate resistance to Aphanomyces root rot (Race 1), anthracnose (Race 1). It has not been tested for Verticillium wilt, stem nematode and pea aphid. 5. Breeder Seed was produced from bulking seed of parent plants planted in isolation to produce Syn. 1 near Sloughhouse, CA in 1991-93. Foundation Seed(Syn. 2) was produced from Breeder Seed and Certified Seed(Syn. 3) from Foundation Seed. One generation each of Breeder, Foundation and Certified Seed are recognized. A maximum of three years each are permitted on stands producing Breeder and Foundation with five years for Certified Seed. Sufficient Breeder Seed for the projected life of the variety will be maintained by Dairyland Research. 6. Certified Seed was available spring of 1998. 7. Application for the Plant Variety Protection is undecided. 8. Information in the NAVRB application can be forwarded to the PVP office. 9. Variety name: Experimental designations. . DS491 Previous Page
