Oneida Ultra

1. Oneida Ultra is a 34-clone synthetic originating from Oneida VR (75%) and multiple germplasm sources in the Cornell breeding program that were selected for multiple diseases resistances, followed by one cycle of phenotypic selection in the field for plant vigor, freedom of diseases, resistance to lodging, and lower forage neutral detergent fiber concentration. This variety is made up of about 46% Flemish, 43% M. varia, 8% M. falcata, 2% Ladak,, <1% Turkestan, and <1% Chilean germplasm sources. Seed of the Syn 1 generation was bulked in equal weight per clone. The Syn 2 generation (breeder seed) was produced in 1992.

2. Oneida Ultra is adapted to the East Central area and intended for use in the Northern USA and Southern Canada for hay, haylage, greenchop, and dehydration. It has been tested in New York, Pennsylvania, and in Ontario, Canada.

3. Oneida Ultra is a moderately dormant variety with fall dormancy similar to the FD 4 check. Flower color of the Syn 2 generation is 100% purple and trace cream, yellow, variegated, and white.

4. Oneida Ultra has high resistance to bacterial wilt, Fusarium wilt, and Verticillium wilt; resistance to anthracnose (Race 1) and Phytophthora root rot; and is susceptible to Aphanomyces root rot (Race 1).

5. In 1992, breeder seed (Syn 2) was produced under cage isolation in Caldwell, ID, in sufficient quantity to last the lifetime of the variety. This seed is maintained under controlled environmental conditions by the Department of Plant Breeding at Cornell University. Foundation seed (Syn 3) may be produced from breeder seed in northern USA on stands no more than 3 years old unless by consent of the breeder. Certified seed (Syn 3 or 4) may be produced from breeder or foundation seed on stands no more than 6 years old.

6. Certified seed was first marketed in 1999.

7. Application for Plant Variety Protection will not be made.
