1. DS013 is a strain crossed synthetic variety. Parent clones were selected out of forage yield plots and/or disease nurseries. These parent plants were progeny tested for one or more of the following traits: forage yield, stand persistence, forage quality, resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot, anthracnose (Race l), Verticillium wilt, Aphanomyces root rot (Race l), and stem nematode. 2. DS013 is adapted and intended for use in the North Central, East Central, Moderately Winterhardy Intermountain and Great Plain regions of the United States. The states in which it has been tested are: Iowa, Minnesota, Nebraska, Pennsylvania, Washington and Wisconsin. 3. DS013 is moderately dormant, fall dormancy 4 variety similar to the fall dormancy checks. Flower color in the Syn.2 generation is 90% purple,7% variegated 1% cream,1% white, and 1% yellow. 4. DS013 has high resistance to Phytophthora root rot, bacterial wilt, Fusarium wilt, anthracnose (Race l), northern root-knot nematode; resistance to Aphanomyces root rot (Race l), Verticillium wilt, pea aphid, blue alfalfa aphid, spotted alfalfa aphid and stem nematode. 5. Breeder seed (Syn. 1) was produced from cuttings of the parent plants that were grown in isolation at Sloughhouse, CA in 1996-97. Seed was bulked in equal proportions each year and lots were kept separate. 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 classes are recognized. A maximum of three years each is permitted on stands producing Breeder and Foundation seed with five years for Certified seed. Dairyland will maintain sufficient Breeder seed for the projected life of the variety 6. Certified seed was available spring of 2003. 7. Application for Plant Variety Protection is anticipated. 8. Information in the NAVRB application can be forwarded to the PVP office. 9. Variety name: Experimental designations: DS013 Date submitted: November 27, 2002 |
