1. Genesis is a synthetic variety
with 201 parent clones. Parent plants trace to 9 populations selected for
resistance to the following pests: bacterial wilt, Fusarium wilt, Verticillium
wilt, Phytophthora root rot, anthracnose and Aphanomyces. Phenotypic recurrent
selection was used. Final selections were made from an Aphanomyces/Phytophthora
root rot evaluation nursery
near Marshfield, Wisconsin based on winter injury, vigor and root development.
Parentage traces to Experimental AP 8635 (39%), Nordic (34%) and Trident
II (27%). Approximate germplasm source contributions are: M. falcata
(8%), Ladak (8%), M. varia (22%), Turkistan (21%), Flemish (32%),
Chilean (5%) and Peruvian (4%).
2. Genesis appears to be adapted to and is intended for use in the North Central U.S. It has been tested in Wisconsin and Iowa.
3. Fall dormancy of Genesis is similar to Ranger. Flower color of Syn 2 generation is approximately 75% purple and 25% variegated with a trace of cream, white and yellow.
4. Genesis has high resistance to anthracnose (race 1), Fusarium wilt, Phytophthora root rot and pea aphid; resistance to Verticillium wilt; and moderate resistance to Aphanomyces (race 1). Reaction to stem nematode, spotted alfalfa aphid, blue alfalfa aphid, bacterial wilt and root knot nematode has not been determined.
5. Seed increase is limited to one generation each of breeder, foundation and certified 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 classes respectively. Foundation seed production is limited to the Pacific Northwest. Breeder seed was produced in 1988. ABI will maintain sufficient seed stocks for the projected life of the variety.
6. Certified seed will be available in 1993.
7. Plant Variety Protection will not be applied for.
