CUF 101
1. CUF 101 was selected from cultivars growing in a 20-acre, over-irrigated hay production field which was 21/2 years old and had been severely infested with the blue alfalfa aphid for about six weeks. Parent plants were selected from the following cultivars: UC Cargo (50), UC Salton (I), UC 76 (20), 1972 breeding mixture (18), and Niagara N71 (2). All parent lines in CUF 101 except Niagara N71 are related to UC Cargo. Approximately 80% of the germplasm in CUF 101 can be traced to UC Cargo.
2. The area of adaptation is the low desert valley areas of Southern California where damage from the blue alfalfa aphid may be severe and winter production is desired. The primary use will be for hay, pasture, green chop, and dehydration.
3. Flower color is purple, growth habit is upright, and it is highly nondormant. CUF 101 has resistance to the blue alfalfa aphid, pea aphid, spotted alfalfa aphid, moderate resistance to root rot, and susceptible to bacterial wilt. Its reaction to anthracnose and stem nematode is not known.
4. Breeder seed is bulked seed from 91 parent plants grown in a cage near El Centro, California, during the summer of 1975. Breeder seed will be maintained by the University of California, Davis. Under certification, the classes of seed will be breeder, foundation, and certified. Areas of seed production and maximum eligibility of a stand to produce a given class of seed shall be determined by the certifying agency in the state where it is certified.
5. Certified seed will first be offered for sale during the fall of 1977.
6. No variety protection is contemplated.
