1. DS9475 is a 25 clone synthetic variety. One half of the parents were selected out of saturated soils near Marshfield, WI. Plants were selected for the branch rooted trait and excellent herbage growth. Source material trace back to 5373, 5472, Nordic, Zenith, Quest, 645, Precedent, Legacy, BlazerXL, Magnum ifi-Wet and Dairyland experimentals. The other half of the parents were selected out of disease evaluation and were progeny tested for one or more of the following traits: forage yield, persistence, forage quality, seed yield, resistance to Phytophthora root rot, anthracnose (Race 1), Verticillium wilt, Aphanomyces root rot (Race 1) and spotted alfalfa aphid. Percentage of this source material trace back to MNB-Pl, Answer, RamRod and Dairyland experimentals. The percent of germplasm sources are: Ladak(1O), M. varia(5), Turkistan(15), Flemish(40) and unknown(27).
2. DS9475 is adapted to the North Central and East Central Region of the United States and intended for use in the upper half of the United States. The state where DS9475 has been tested is: Wisconsin.
3. DS9475 is a dormant variety similar to Ranger in fall dormancy. Flower color in the Syn. 2 generation is 90% purple, 10% variegated with trace amount of cream, white and yellow. In poorly drained soils, DS9475 expresses branch rooted tendencies.
4. D59475 has high resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot; resistant to Verticillium wilt, pea aphid, Aphanomyces root rot (Race 1), and anthracnose (Race 1) and moderate resistance to blue alfalfa aphid. Its reaction to spotted alfalfa aphid, stem nematode and northern root-knot nematode has not been tested.
5. Breeder Seed was produced from bulking seed of parent plants planted in cage isolation to produce Syn. 1 near Sloughhouse, CA in 1993. 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.
