1. DK127 is a synthetic variety with 161 parent plants. Parents were selected from a cross between two FG breeding lines for multifoliolate leaf expression and combined resistance to Aphanomyces root rot (race 1) and Phytophthora root rot . One line traces to selections from a four year old Minnesota yield trial and the other to a winterhardy multifoliolate population selected for vigor, persistence, forage quality and resistance to one or more of the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, anthracnose (race 1), Phytophthora root rot, and Aphanomyces root rot (race 1). Phenotyic recurrent selection was used. Parentage traces to the following cultivars: Pacesetter (35%), LegenDairy (20%), Encore (20%), Alfaleaf (15%), Prism (5%), and DK133 (5%). Approximate germplasm source contributions are: M.falcata-6%, Ladak-6%, M.varia-30%, Turkistan-3%, Flemish-52%, and Chilean-3%.
2. DK127 is adapted to the North Central and East Central regions of the U.S. and intended for use in the northern and central U.S. It has been tested in Wisconsin, Minnesota, Iowa and Pennsylvania.
3. Fall dormancy of DK127 is similar to Ranger and winter survival of this variety is similar to Vernal. Flower color in the Syn2 is 79% purple, 21% variegated, and a trace of white, cream and yellow. DK127 has greater multifoliolate leaf expression than Multiking I.
4. DK127 has high resistance to bacterial wilt, anthracnose (race 1), Phytophthora root rot, Aphanomyces root rot (race 1), spotted alfalfa aphid and pea aphid; resistance to Verticillium wilt, Fusarium wilt, northern root knot nematode and stem nematode; and moderate resistance to blue alfalfa aphid.
5. Seed increase is on a limited generation basis with one generation of breeder and two generations of foundation and certified seed classes. Breeder (Syn1), foundation (Syn2 or Syn3), and certified (Syn3 or Syn4) classes will be recognized. Production of Syn3 foundation seed requires the consent of the breeder. Breeder seed was produced at Caldwell, Idaho in 1992. Sufficient foundation seed for the projected life of the variety will be maintained by Forage Genetics. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.
6. Certified seed will be marketed in 1995.
7. No decision has been made concerning Plant Variety Protection .
