CW 56078
1 CW 56078 is a synthetic variety with 111 parent plants. Parent plants were selected for persistence and vigor following two years of close continuous grazing with both cattle and sheep at Woodland, California. Parentage of CW 56078 traces to the following germplasm sources: Express and SPS 6550. Approximate germplasm source contributions are asfollows: M. falcata (1%), Ladak (2%), M. varia (10%), Turkistan (13%), Flemish (34%), Chilean (12%), Peruvian (1%), Indian (7%), African (14%), and unknown (6%).
2. CW 56078 is adapted to the southwest and moderately winter hardy intermountain areas of the U.S. and is intended for use in the southwest area of the U.S., Argentina, South Africa, and Australia. CW 56078 has been tested in California.
3. CW 56078 is a moderately dormant variety with fall dormancy similar to FD class 6 check varieties. Flower color observed in the syn2 generation is approximately 99% purple, 1% variegated, with a trace of white, cream, and yellow. CW 56078 has tolerance to intensive grazing with high stocking rates similar to the tolerant check variety Alfagraze.
4. CW 56078 has high resistance to anthracaose (race 1), Fusarium wilt, Phytophthora root rot, pea aphid, spotted alfalfa aphid, and blue alfalfa aphid, with resistance to stem nematode. Reaction to bacterial wilt, Verticillium wilt, Aphanomyces root rot (race 1), and root knot nematode has not been adequately tested.
5. Seed increase of CW 56078 is on a limited generation basis with one generation of breeder and two generations of the foundation and certified seed classes. Breeder (syn1), foundation (syn2 or 3), and certified (syn3 or 4) classes will be recognized. Production of syn3 foundation seed requires consent of the breeder. Breeder seed was produced under open isolation near woodland, California, in 1995. 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 three and six years, respectively.
6. Certified seed of CW 56078 will be available in 2000.
7. No decision has been made regarding Plant Variety Protection.
