C 241 (Amended) 

 

1.  C 241 is a 200-plant synthetic variety resulting from phenotypic recurrent selection for resistance to Verticillium wilt. Source material traces to Valley +, WL 457, WL 414 and Archer. Approximate germplasm source contributions are Arabian (46%), Chilean (32%), Peruvian (12%), Indian (5%) and African (5%).

2.  C 241 is adapted to and intended for use in the Southwestern United States. C 241 has been yield tested in California.

3.  Flower color of C 241 at Syn. 2 approximates 100% purple with a trace of variegated and white. The fall dormancy of C 241 is similar to ABI 700 (Class 6).

4.  C 241 has high resistance to Fusarium wilt, Verticillium wilt and Phytophthora root rot; resistance to anthracnose, bacterial wilt, stem nematode, pea aphid, spotted alfalfa aphid, blue alfalfa aphid and northern root knot nematode; and moderate resistance to southern root-knot nematode (M. incognita). Reaction to Aphanomyces root rot (Race 1) has not been adequately tested. 

5.  Breeder seed (Syn. 1) was produced in 1995 on 200 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 WL Research. One generation of breeder (Syn. 1), two generations of foundation (Syn. 2 or 3), and three generations of certified (Syn. 2, 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.

6.  Certified seed will be marketed in 2002.

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

8.  Information in this application can be turned over to the PVP office.

9.  Variety Name:  C 241.

     Experimental designation:  C 241.
