GoldPlus
1. Gold Plus is a synthetic variety with 165 parent plants which were selected sequentially for multifoliolate leaf expression and for resistance to Phytophthora root rot and Aphanomyces root rot (race 1). Parent plants were selected from a polycross among selections from three year old Wisconsin yield trials. Parentage of Gold Plus traces to the following germplasm sources: MultiQueen, VS-9034, AlfaStar, and DK 122. Approximate germplasm source contributions are as follows: M. falcata (8%), Ladak (6%), M. varia (25%), Turkistan (4%), Flemish (47%), and Chilean (10%).
2. Gold Plus is adapted to the North Central U. S. and is intended for use in the northern and central U. S. . Gold Plus has been tested in Wisconsin, Minnesota, and Iowa.
3. Gold Plus is a moderately dormant variety with fall dormancy similar to Saranac. Flower color observed in the Syn. 2 generation is approximately 99% purple, 1% variegated, and a trace of cream, white and yellow. Forage quality of Gold Plus is similar to WL322HQ. Gold Plus has greater multifoliolate leaf expression than MultiKing I.
4. Gold Plus has high resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot, anthracnose (race 1), pea aphid, spotted alfalfa aphid, and stem nematode, with resistance to Verticillium wilt and Aphanomyces root rot (race 1). Reaction to root knot nematode and blue alfalfa aphid has not been adequately tested.
5. Seed increase of Gold Plus is on a limited generation basis with two generations of the breeder, foundation and certified seed classes. Breeder (Syn. I or Syn. 2), foundation (Syn. 2 or Syn. 3), and certified (Syn3 or Syn. 4) classes will be recognized. Production of Syn. 2 breeder or Syn 3 foundation seed requires the 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 be maintained by Cal/West Seeds. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.
6. Certified seed of Gold Plus will be available in 1996.
7. No decision has been made regarding Plant Variety Protection.
