UC Cibola
1. The parent plants of UC Cibola were selected from a 3 year alfalfa stand growing in a sandy soil infested with four genera of root nematodes. The field had also been infested with blue alfalfa aphids prior to selection. Parents are 46, 26, 28 plants, respectively, from UC Salton, UC 76, and UCPX 1971.
2. The probable area of adaptation will be areas in the Palo Verde Valley of California (Blythe) infested with root nematodes. It has been tested in the low desert valleys and San Joaquin Valley of California. The primary use will be for hay production.
3. It is nondormant, purple-flowered, and erect in growth habit.
4. It is susceptible to bacterial wilt and has low resistance to the blue alfalfa aphid, moderate resistance to Phytophthora root rot, resistance to the pea aphid and the root-knot nematode Meloidogyne hapla, high resistance to Fusarium wilt and the spotted alfalfa aphid, and survives well in fields infested with four or more genera of root nematodes where it is adapted in the Palo Verde Valley of California.
5. Seed classes will be breeders (produced in a cage in 1977 and 1978), foundation and certified. Breeder and foundation seed will be maintained by the University of California Foundation Seed Project, Davis. Areas of seed production and maximum eligibility of stand to produce a given class of seed shall be determined by the certifying agency in the state where it is certified.
6. Certified seed will be available in 1984.
7. No plant variety protection is contemplated.
