90-124 1. 90-124 is a 140-plant synthetic variety resulting from phenotypic recurrent selection for high forage quality (high crude protein, low acid and neutral detergent fibers) using Near Infrared Reflectance Spectroscopy (NIRS). Source material traces to two elite experimental lines selected for resistance to Phytophthora root rot. Subsequent selection was performed for winter survival in a field nursery at Evansville, WI. Parental germplasm traces to Royalty, Arrow, Vernal, and Vertus. Approximate germplasm source contributions are: M. falcata -8%; Ladak -11%; M. varia -27%; Turkistan -7%; Flemish -42%; and Chilean -5%. 2. 90-124 is adapted to and intended for use in the northwest, north central, and northeastern U.S. 90-124 has been yield tested in New York, Wisconsin, and Washington. 3. Flower color at Syn 2 of 90-124 approximates 99% purple and 1% variegated with traces of cream, white, and yellow. Its fall dormancy is similar to that of Ranger. 90-124 appears to have high forage quality (high crude protein, low acid and neutral detergent fiber), similar to WL 322 HQ. 4. 90-124 has high resistance to anthracnose (Race 1), bacterial wilt, Fusarium wilt, and Phytophthora root rot; resistance to Verticillium wilt and pea aphid; moderate resistance to the spotted alfalfa aphid and stem nematode; and low resistance to Aphanomyces root rot (Race 1). Reaction to blue alfalfa aphid and root knot nematode has not been adequately tested. 5. Breeder seed (Syn 1) was produced in 1990 on 140 plants under cage isolation at Bakersfield, CA. Sufficient Foundation (Syn 2) seed was produced near Warden, WA for the expected life of the variety and will be maintained by W-L Research. One generation of Breeder (Syn 1) and two generations each of Foundation (Syn 2 or 3) and Certified (Syn 3 or 4) seed are recognized. The maximum permitted length of stand for Foundation and Certified seed fields are 3 and 5 years, respectively. Foundation seed must be produced above 40 degrees North latitude. Production of Syn 3 Foundation seed requires consent of the breeder. 6. Certified seed will be marketed in 1993. 7. It is undecided whether application will be made for Plant Variety Protection. 8. The information in this application is available to the PVP office.
