1. GH 767 is a synthetic variety with 172 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 various populations that were developed by phenotypic recurrent selection for high relative feed value (using Near Infrared Reflectance Spectroscopy), for multifoliolate leaf expression, and for resistance to one or more of the following pests: bacterial wilt, Aphanomyces root rot (race 1), Phytophthora root rot, anthracnose (race 1), Verticillium wilt, Leptosphaerulina leafspot, and spotted alfalfa aphid. Parentage of GH 767 traces to the following germplasm sources: Class, DK 122, Multiplier, Alfaleaf, Chief, Crown II, VS-775, and WL 320. Approximate germplasm source contributions are as follows: M.falcata (8%), Ladak (6%), M.varia (25%), Turkistan (5%), Flemish (46%), and Chilean (10%).
2. GH 767 is adapted to the North Central and East Central U.S. and is intended for use in the northern and central U.S. GH 767 has been tested in Wisconsin, Minnesota, and Pennsylvania.
3. GH 767 is a dormant variety with fall dormancy similar to Vernal. Flower color observed in the Syn.2 generation is approximately 82% purple, 14% variegated, 4% cream, and a trace of white and yellow. GH 767 has greater multifoliolate expression than Multiking I.
4. GH 767 has high resistance to bacterial wilt, Fusarium wilt, anthracnose (race 1), Phytophthora root rot, and pea aphid, and resistance to Verticillium wilt, Aphanomyces root rot (race 1), stem nematode, and spotted alfalfa aphid. Reaction to root knot nematode and blue alfalfa aphid has not been adequately tested.
5. Seed increase of GH 767 is on a limited generation basis with one generation of breeder and two generations of the foundation and certified seed classes. Breeder (Syn.l), foundation (Syn.2 or Syn.3), and certified (Syn.3 or Syn.4) classes will be recognized. Production of Syn.3 foundation seed requires consent of the breeder. Breeder seed was produced under cage isolation at Woodland, California in 1991. 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 GH 767 will be available in 1995
7. No decision has been made regarding Plant Variety Protection.
