DK 194
1. DK 194 is a synthetic variety with 128 parent plants which were selected for aphid resistance, drought tolerance, frost tolerance, persistence and agronomic characteristics from space planted nurseries and yield trials in Argentina. Parent plants were selected from various populations which were developed by a combination of phenotypic recurrent selection and strain crossing with selection for resistance to one or more of the following pests: Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1), spotted alfalfa aphid, blue alfalfa aphid, and stem nematode. Parentage of DK 194 traces to Topacio, DK 192, Grasis, ACA 900, Super Supreme, Mecca, F969, DK 191, and miscellaneous Cal/West Seeds breeding populations. Approximate germplasm source contributions are as follows: M. varia (2%), Turkistan (11%), Flemish (3%), Chilean (8%), Peruvian (3%), Indian (23%), African (45%), and Unknown (5%).
2. DK 194 is adapted to the Southwestern area of the U.S. and Argentina and is intended for use in the Southwestern U.S. and Argentina. DK 194 has been tested in California and Argentina.
3. DK 194 is a very nondormant variety with fall dormancy similar to FD9 checks. Flower color observed in the Syn.2 generation is greater than 99% purple, with a trace of variegated, cream, white, and yellow.
4. DK 194 has high resistance to anthracnose (race 1), Fusarium wilt, spotted alfalfa aphid, and blue alfalfa aphid, with resistance to Phytophthora root rot, stem nematode, pea aphid, and northern root knot nematode. Reaction to bacterial wilt, Verticillium wilt, and Aphanomyces root rot (race 1) has not been adequately tested
5. Seed increase of DK 194 is on a limited generation basis with one generation of breeder and two generations of the foundation and certified seed classes. Breeder (Syn D, foundation (Syn.2 or Syn.3), and certified (Syn.3 or Syn.4) classes will be recognized. Production of Syn.3 foundation seed requires consent of the breeder. Breeder seed was produced under cage isolation near Mendoza, Argentina in 1997. Sufficient foundation seed for the projected life of the variety will be maintained by Cal/West Seeds. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.
6. Certified seed of DK 194 will be available in 2000.
7. No decision has been made regarding Plant Variety Protection.
