RADIANT
1. Radiant is a synthetic variety with 250 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 two populations: crosses between selections fromthree year old Wisconsin nurseries which were derived from various populations which weredeveloped by phenotypic recurrent selection for high relative feed value (using Near InfraredReflectance Spectroscopy), and for resistance to one or more of the following pests: bacterialwilt, Verticillium wilt, Phytophthora root rot, Aphanomyces root rot (race 1), anthracnose (race1), and Leptosphaerulina leafspot; crosses betweenselections for crown rot resistance andpersistence from dime year old Wisconsin, Minnesota, and Iowa yield trials. Parentage ofRadiant traces to the following germplasm sources: 9236, WinterKing, Maximum 1, Hunter, andmiscellaneous Cal/West Seeds breeding populations. Approximate germplasin sourcecontributions are as follows: Mfialcata (8%), Ladak (6%), M. varia (25%), Turkistan (4%),Flemish (48%), and Chilean (9%).
2. Radiant is adapted to and intended for use in the north central, east central, and Great PI areasof the U.S. Radiant has been tested in Wisconsin, Minnesota, Iowa, Michigan, Pennsylvania, andNebraska.
3. Radiant is a moderately dormant variety with fall dormancy similar to FD class 4 checkvarieties. Flower color observed in the syn2 generation is approximately 991/o purple, 1%variegated, with a trace of white, cream, and yellow.
4. Radiant has high resistance to anthracnose (race 1), bacterial wilt, Fusarium. wilt, Verticilliumwilt, Phytophthora root rot, and Aphanomyces root rot (race 1), with resistance to spotted alfalfaaphid, pea aphid, and stem nematode. Reaction to blue alfalfa aphid and root knot nematode hasnot been adequately tested.
5. Seed increase of Radiant 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 (syn3 or 4) classes will be recognized. Production of syn3 foundation seedrequires consent of the breeder. Breeder seed was produced under cage isolation near Woodland,California, in 1996. 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 Radiant will be available in 1999.
7. No decision has been made regarding Plant Variety Protection.
