1. VS-9030 is a synthetic variety with 43 parent plants. Parents were selected for multifolilate expression and resistance to one or more of the following pests: bacterial wilt, Verticillium wilt, anthracnose, Phytophthora root rot, Aphanomyces root rot, Leptosphaerulina leaf spot and spotted alfalfa aphid. Phenotypic recurrent selection was used. The following germplasm sources were used in the development of this variety: Achieva (28%), Encore (25%), Alfaleaf (22%), Prism (12%), 2833 (8%) and DK122 (5%). Approximate germplasm source contributions are: M. falcata -6%, Ladak -6%, M. varia -26%, Turkistan -3%, Flemish -54% and Chilean -5%.
2. VS-9030 is adapted to the northeastern and northcentral U.S. and intended for use in the northern and central U.S. It has been tested in Wisconsin, Minnesota, Iowa and New York.
3. VS-9030 is a dormant variety. Fall dormancy is similar to Ranger. Flower color in the Syn. 1 is 78% purple, 22% variegated and a trace of white, yellow and cream. At first flower in autumn approximately 98% of the plants show multifoliolate expression.
4. VS-9030 has high resistance to bacterial wilt, anthracnose (race 1), Aphanomyces root rot (race 1), pea aphid and Phytophthora root rot with resistance to Fusarium wilt, Verticillium wilt, and spotted alfalfa aphid. Reaction to stem nematode, root knot nematode and blue alfalfa aphid have 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 (Syn 1), foundation (Syn
2 or Syn 3), and certified (Syn 3 or Syn 4) classes will be recognized.
Production of Syn 3
foundation seed requires the
consent of the breeder. Breeder seed was produced under cage isolation
at Woodland, California in 1990. Sufficient foundation seed for the
projected life of the variety will be maintained by VISTA. Stands of foundation
and certified seed fields are limited to 3 and 6 years, respectively.
6. Certified seed will be marketed in 1994.
7. No decision has been made concerning Plant Variety Protection.
