1. DK124 is a synthetic variety with 18 parent clones. Parents were selected based on clonal and/or polycross progeny tests for forage yield, forage quality, fall dormancy reaction, persistence, pest resistance and multifoliolate leaf expression from several breeding populations previously selected for resistance to one or more of the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, anthracnose (Race 1) and spotted alfalfa aphid. A combination of genotypic and phenotypic recurrent selection was used in the development of this variety. The parental populations from which all clones were derived trace to the gerfollowing cultivars: DK127 (25%), Lightning (20%), LegenDairy 2.0 (15%), Rushmore (10%), Excalibur II (10%), 5262 (10%), Magnum III (5%) and G2852 (5%). Syn1 was produced near Nampa, ID in 1995, harvested in total and bulked to form breeder seed. Approximate implasm source contributions are: M. falcata (6%), Ladak (4%), M. varia (32%), Turkistan (3%), Flemish (52%), and Chilean (3%).
2. This variety is adapted to the North Central United States and intended for use in the North Central, East Central, Winterhardy Intermountain of the United States. and Eastern Canada. This variety has been tested in Wisconsin, Minnesota and Iowa.
3. This variety has fall dormancy similar to FD3 checks and winter survival similar to WS1 checks. Flower color (Syn2) is 87% purple, 9% variegated, 3% yellow and 1% white, with a trace of cream. DK124 has high multifoliate leaf expression.
4. This variety has high resistance to bacterial wilt, Fusarium wilt, anthracnose (Race 1), Phytophthora root rot, Verticillium wilt and Aphanomyces root rot (Race 1); resistance to pea aphid and blue aphid; and moderate resistance to northern root knot nematode and stem nematode. Reaction to spotted alfalfa aphid has not been tested.
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 consent of the breeder. Breeder seed was produced near Nampa, Idaho in 1995. 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 5 years, respectively.
6. Certified seed will be marketed in 1999.
