NEMIESIS
1. Nemesis is a synthetic variety with 157 parent plants which were selected sequentially formultifoliolate leaf expression and for resistance to Phytophthora root rot and Aphanomyces rootrot (race 1). Parent plants were selected from crosses between selections from three year oldWisconsin nurseries that were derived from various populations which were developed byphenotypic recurrent selection for high relative feed value (using Near Infrared ReflectanceSpectroscopy), and for resistance to one or more of the following pests: bacterial wilt, verticillium wilt, Phytophthora root rot, Aphanomyces root rot (race 1), anthracnose (race 1),and Leptosphaerulina. leafspot. Parentage of Nemesis traces to the following germplasmsources: Ultraleaf87, Tartan, GH 787, MultiQueen, and miscellaneous Cal/West Seeds breedingpopulations. Approximate germplasm. source contributions are as follows: M. falcata (8%),Ladak (6%), M. varia (25%), Turkistan (4%), Flemish (47%), and Chilean (10%).
2. Nemesis is adapted to the north central areas of the U.S. and is intended for use in the northcentral and east central areas of the U.S ~ Nemesis has been tested in Wisconsin, Minnesota, andIowa.
3. Nemesis is a moderately dormant variety with fall dormancy similar to Ranger. Flower colorobserved in the syn2 generation is greater than 85% purple and 13% variegated, and 2% yellow,with a trace of white and cream.
4. Nemesis has high resistance to anthracnose (race 1), bacterial wilt, Fusarium. wiltVerticillium wilt, Phytophthora root rot, Aphanomyces root rot (race 1), and pea aphid, withresistance to stem nematode and spotted alfalfa aphid. Reaction to blue alfalfa aphid and rootknot nematode has not been adequately tested.
5. Seed increase of Nemesis is on a limited generation basis with one generation of breeder andtwo generations of the foundation and certified seed classes. Breeder (syn1), foundation (syn 2or 3), and certified (syn.3 or 4) classes will be recognized. Production of syn3 foundation seedrequires consent of the breeder. Breeder seed was produced under cage isolation at Woodland,California, in 1993. Sufficient foundation seed for the projected life of the variety will bemaintained by Cal/West Seeds. Stands of foundation and certified seed fields are limited to threeand six years, respectively.
6. Certified seed of Nemesis will be available in 1998.
7. No decision has been made regarding Plant Variety Protection.
