FG6B175
1. FG 6B 175 is a synthetic variety with 140 parent plants. Parent plants were selected for seed yield, multifoliolate expression and resistance to one or more of the following pests: anthracnose, Fusarium wilt, Verticillium wilt and Phytophthora root rot. Germplasm sources used in developing FG 6B175 were DKl66 (70%) and Tahoe (30%). Breeder seed (Syn I) was produced near Nampa, Idaho in 1992. Seed was harvested in total on all parents and bulked to form breeder seed. Approximate germplasm source contributions are: M. falcata (1%), Ladak (1 0%), M. varia (6%), Turkistan (20%), Flemish (11%), Chilean (14%), Peruvian (1%), Indian (17%), African (1 7%) and unknown (3%).

2. This variety is adapted to Moderately Winterhardy Intermountain and Winterhardy Mountain areas of the U. S. This variety has been tested in Idaho and California. It will be used in moderate winterhardy regions of the Intermountain Western U. S.

3. This variety has fall dormancy similar to FD6 checks. Flower color (Syn2) is 100% purple.

4. This variety has high resistance to Fusarium wilt, anthracnose (Race I), Phytophthora root rot, pea aphid, spotted alfalfa aphid; and resistance to Verticillium wilt, blue alfalfa aphid and root knot nematode . hapla); and moderate resistance to bacterial wilt and stem nematode. Reaction to Aphanomyces root rot has not been tested.

5. Seed increase is on a limited generation basis with one generation of breeder and two generations of foundation and certified seed classes. Breeder (Syn I), 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 near Nampa, Idaho in 1992. Sufficient foundation seed for the projected life of the variety will be maintained by Forage Genetics. Stands of foundation and certified seed fields are limited to 3 and 6 years, respectively.

6. Certified seed will be marketed in 1998.

7. No decision has been made concerning Plant Variety Protection.
