ZC 9854A
1. ZC 9854A was selected for resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium wilt, Phytophthora root rot, anthracnose (race 1) and Aphanomyces root rot (races 1 and 2). Phenotypic recurrent selection was used. Final selections were made from 2-3 year old space plant selection nurseries near Larned, Kansas, Napier, Iowa and Livingston, Wisconsin based on yield, winter survival, fall dormancy, leafhopper yellowing and leaf disease. Breeder seed (syn 1) was produced in 1998 near Nampa, Idaho on approximately 25 cuttings of each clone transplanted at random and harvested in bulk.
2. ZC 9854A is adapted to the North Central and East Central Regions of the U.S. It is intended for use in the North Central and East Central Regions of the U.S. It has been tested in Iowa, Wisconsin, and Illinois.
3. ZC 9854A is moderately dormant, similar to the FD 5 check. Flower color of syn 2 generation is approximately 74% purple and 26% variegated with a trace of white, cream and yellow.
4. ZC 9854A has high resistance to bacterial wilt, Fusarium wilt, Verticillium wilt, anthracnose (race 1), Phytophthora root rot and Aphanomyces root rot (race 1), moderate resistance to Aphanomyces root rot (race 2), pea aphid, blue alfalfa aphid and spotted alfalfa aphid and low resistance to stem nematode. It has not been evaluated for resistance to root knot nematode.
5. Seed increase is limited to one generation each of breeder (syn 1), foundation (syn 2) and certified (syn 3) seed classes. Certified seed may be produced from either breeder or foundation classes. A 1, 3 and 6 year stand life is permitted on fields producing breeder, foundation and certified seed classes respectively. Foundation seed production is limited to the Pacific Northwest. Breeder seed was produced in 1998. ABI will maintain sufficient seed stocks for the life of the variety.
6. Certified seed will be available in 2002.
7. Plant Variety Protection will not be applied for.
