5715

1.. 5715 is a 102 plant synthetic cultivar with parents selected through phenotypic recurrent selection originating from several experimental lines tracing to BAA 17, BAA 20, CUF 101, Moapa 69, Lahontan, N71 Brand, UC Cargo, UCPX, UC Salton and others with minor contributions. Parent plants were selected for one or more of the following: anthracnose, blue alfalfa aphid, and Phytophthora root rot. Germplasm sources are: M.varia (1%), Turkistan (10%), Flemish, Chilean (9%), Indian (9%), African (33%), with (36%) unknown.

2. 5715 is intended for use in the San Joaquin and Imperial valleys of California and the low desert areas of Arizona, California, New Mexico and Texas for hay, haylage, greenchop and dehydration. It is expected to be adapted where other nondormant alfalfas are grown. 5715 has been tested in California using the following experimental designation: XAIB1, YAIB1 and 86PN741.

3. 5715 is a nondormant variety with fall dormancy similar to Moapa 69. Flower color of the Syn 2 generation is approximately 93% purple and 7% variegated. Growth habit is erect in mid-summer and erect in fall.

4. 5715 has high resistance to anthracnose, Fusarium wilt, blue alfalfa aphid and spotted alfalfa aphid; resistance to Phytophthora root rot and pea aphid; low resistance to bacterial wilt and Verticillium wilt. It has not been adequately tested for stem nematode.

5. Breeder seed (Syn 1) was produced over a two year period on parent plants in "cage isolation" and bulked. Seed classes will be breeder, foundation (Syn 2 or Syn 3), and certified (Syn 2, Syn 3 or Syn 4). Foundation seed may be produced from breeder or foundation. The second generation foundation may be produced at the discretion of Pioneer Hi--Bred International, Inc. Limitation on ages of stand will be three and five years for foundation and certified seed, respectively. Sufficient breeder and foundation seed for the projected life of the variety will be maintained by Pioneer Hi--Bred International, Inc.

6. Seed will be marketed in the fall of 1990.

7. Application for Plant Variety Protection will be made and the certification option will not be requested.

8. As a means of added varietal protection, information included with Application for Review of Alfalfa Variety for Certification may be provided to the PVP office.
