Platinum

 

 

  1. Platinum is a 220-plant synthetic variety resulting from phenotypic recurrent selection for high forage quality using near infrared reflectance spectroscopy. Parental germplasm traces to Multi-plier, ALPHA 2001, WL 252 HQ and WL 322 HQ. Approximate germplasm source contributions are M. facata – 15%; Ladak – 10%; M. varia – 25%; Turkistan – 21%; Flemish – 26%; and Chilean – 3%.

  1. Platinum is adapted for use in the North Central, East Central and moderately winterhardy intermountain regions of the United States. Platinum has been yield tested in Pennsylvania, Washington and Wisconsin.

  1. Flower color of Platinum at Syn 2 approximates 100% purple with a trace of variegated and cream. The fall dormancy of Platinum is similar to Legend (Class 4).

  1. Platinum has high resistance to anthracnose (Race 1), bacterial wilt, Fusarium wilt, Verticillium wilt, pea aphid, Aphanomyces root rot (Race 1) and Aphanomyces root rot (Race 2); and resistance to stem nematode. Reaction to spotted alfalfa aphid, blue alfalfa aphid, Phytophthora root rot and root knot nematode has not been adequately tested.

  1. Breeder seed (Syn 1) was produced in 1996 on 220 plants under cage isolation at Bakersfield, California. Sufficient foundation (Syn 2) seed will be produced 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 three and five years, respectively. Foundation seed must be produced above 40 degrees North latitude. Production of Syn 3 Foundation seed requires consent of the breeder.

  1. Certified seed will be marketed in 1999.

  1. It is undecided whether application will be made for Plant Variety Protection.

  1. The information in this application can be turned over to the PVP office.
