5333

1. 5333 in a synthetic variety comprised from 145 plants originating from experimental lines tracing to 5432, 532, 120, 524, NCMP10, MSACW3AN4, Vernal, Armor, Magnum, Mercury, 5444, Apollo, 521, Agate, Endure, Futura, 526, 5364, 555, B7AC3AN1, Honeoye, Europe, Vertus, Daer Feldt, Culver, MSA--C4, MSB--C4, 520, Iroquois, Narragansett, Team, Cherokee, Arnim, Saranac AR, Dawson, Anchor, DuPuits, 530, 531, and others with minor contributions. Parent plants were selected through phenotypic recurrent selection from various experimental lines for one or more of the following: Bacterial wilt, Fusarium wilt, anthracnose, Verticillium wilt, Phytophthora root rot and expression of multifoliolate leaves. Germplasm sources are: M.falcata (6%), Ladak (10%), M. varia (27%), Turkistan (6%), Flemish (27%), Chilean (6%), with (18%) unknown.

2. 5333 is adapted to and intended for use in the central and northern region of the United States for hay, haylage, greenchop and dehydration. The states in which 5333 have been tested are: Iowa, Illinois, Maryland, Minnesota, New York, Pennsylvania, Wisconsin, Oregon and Washington.

3. 5333 is a moderately dormant cultivar with fall dormancy similar to Saranac. Flower color in the Syn 2 generation is approximately 88% purple, 12% variegated and a trace of yellow, white and cream. Growth habit is erect in midsummer and semi--erect in the fall. Approximately 50% of the plants and/or stems express multifoliolate leaves in the field at full bloom.

4. 5333 has high resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, and pea aphids; resistance to anthracnose (race 2), Phytophthora root rot and spotted alfalfa aphid; moderate resistance to Verticillium wilt; low resistance to stem nematode. 5333 has not been tested for blue alfalfa aphid.

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. Limitations on ages of stand will be three and five years, respectively, for foundation and certified seed. 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 spring of 1991.

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 the Application for Review of Alfalfa variety for Certification may be provided to the PVP office.
