1. DS681FQ is a 120 clone synthetic variety. One half of the parent plants were selected out of forage yield plots and/or disease nurseries. These parent plants were evaluated for Fusarium wilt, stem nematode, root-knot nematode, spotted alfalfa aphid resistance; crown health, fall dormancy and seed production. The other half of the parent plants were selected for visual forage quality characteristics, plant vigor and seed production. The percent of germplasm sources are: M. varia (2), Turkistan (5), Flemish (4), Chilean (12), Peruvian (10), Indian (20), African (15) and Unknown (32).
2. DS681FQ is adapted and intended for use in the Southwestern Region of the United States. The states where it has been tested are California and New Mexico.
3. DS681FQ is a non-dormant variety similar to the fall dormancy 8 check. Flower color in the Syn. 2 generation is 85% purple, 15% variegated with trace amounts of cream, white and yellow.
4. DS681FQ has high resistance to Fusarium wilt, northern root-knot nematode (M. hapla), southern root-knot nematode (M. incognita); resistance to bacterial wilt, stem nematode, pea aphid and moderate resistance to anthracnose (Race 1) and Verticillium wilt. DS681FQ has not been tested against spotted alfalfa aphid, blue alfalfa aphid, Phytophthora root rot and Aphanomyces root rot (Race l).
5. Breeder seed (Syn. 1) was produced by bulking seed of parent plants which were grown in field isolation near Sloughhouse, CA in 1995. Seed from parental clones were equally bulked. Foundation seed (Syn.2) was produced from Breeder seed and Certified seed (Syn. 2Or3) from either Breeder or Foundation seed. One generation each of Breeder, Foundation and two generations of Certified seed classes are recognized. A maximum of three harvest years each is permitted on stands producing Breeder and Foundation seed with five years for Certified seed. Dairyland Research International will maintain sufficient Breeder seed for the projected life of the variety.
6. Certified Seed will be available fall of 2000.
7. Application for the Plant Variety Protection is undecided.
