GoldLeaf
1. GoldLeaf is a 10 clone synthetic variety. Parent clones were selected out of forage yield plots and/or disease nurseries. These parent plants were progeny tested for one or more of the following traits: forage yield, stand persistence, forage quality, resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot, anthracnose (Race l), Verticillium wilt, Aphanomyces root rot (Race l), and spotted alfalfa aphid. The percent of germplasm sources are: Ladak (15), M. varia (l2), Turkistan (l5), Flemish (35), Chilean (8), and Unknown (15).
2. GoldLeaf is adapted to and intended for use in the North Central, Great Plains and East Central Region of the United States. The states where it has been tested are Minnesota, Iowa, Nebraska and Wisconsin.
3. GoldLeaf is a dormant variety similar to the fall dormancy 3 check. Flower color in the Syn. 2 generation is 90% purple, 10% variegated with trace amounts of cream, white and yellow.
4. GoldLeaf has high resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot and northern root-knot nematode (M. hapla); resistance to Aphanomyces root rot (Race l), pea aphid, stem nematode, Verticillium wilt and anthracnose (Race 1). It has not been tested for spotted alfalfa aphid and blue alfalfa aphid.
5. Breeder seed(Syn. 1) was produced from bulking seed of parent plants which were grown in field isolation near Sloughhouse, CA in 1993-94. Seed from parental clones were equally bulked and seed lots were kept separate. Foundation seed (Syn.2) was produced from Breeder seed and Certified seed (Syn. 2Or3) from either Breeder or Foundation seed. One generation each of Breeder, Foundation and two generations of Certified seed classes are recognized. A maximum of three harvest years each is permitted on stands producing Breeder and Foundation seed with five years for Certified seed. Sufficient Breeder seed for the projected life of the variety will be maintained by Dairyland Research International.
6. Certified Seed will be available fall of 2000.
7. Application for the Plant Variety Protection is undecided.
