1. C/W 2995 is a synthetic variety with 636 parent plants which were selected from populations that were developed by phenotypic recurrent selection and strain crossing. Parent plants were selected for resistance to one or more of the following pests: anthracnose, Phytophthora root rot, and Stagnospora root and crown rot. The following germplasm sources were used in the development of C/W 2995: Mecca and VS-446. Approximate germplasm source contributions are as follows: Ladak (1%), M.varia (2%), Turkistan (11%), Flemish (1%), Chilean (10%), Peruvian (2%), Indian (19%), African (45%), and Unknown (9%).
2. C/W 2995 is adapted to the Sacramento Valley and San Joaquin Valley of California and is intended for use in the San Joaquin and Imperial Valleys of California and similar low desert valleys in California and Arizona. C/W 2995 has been tested in California.
3. C/W 2995 is a very nondormant
variety with fall dormancy similar to CUF-101. Flower color observed in
the Syn.1 generation is approximately 99% purple and 1% variegated.
4. C/W 2995 has high resistance
to spotted alfalfa aphid with resistance to Fusarium wilt, pea aphid, and
blue alfalfa aphid. It has moderate resistance to Verticillium wilt and
Phytophthora root rot. C/W 2995 is susceptible to anthracnose (race
1). Reaction to bacterial wilt, stem nematode, root knot nematode, and
Aphanomyces root rot has not been adequately tested.
5. Seed increase is on a limited
generation basis with one generation of breeder and two generations of
the foundation and certified seed classes. Breeder (Syn.1), foundation
(Syn.2 or Syn.3), and certified (Syn.3 or Syn.4) classes will be recognized.
Production
of Syn.3 foundation seed requires
the consent of the breeder. Breeder seed was produced under cage
isolation at Woodland, CA in 1988. 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 3 and 6 years, respectively.
6. Certified seed of C/W 2995 will be available in 1993.
7. No decision has been made concerning Plant Variety Protection.
