Salado (Amended)
November 20,2000
1. Salado is a synthetic variety with 200 parent clones. Parent clones trace to two populations selected for increased germination and forage yield under saline (NaCI) stress. The basis of selection was a modification of the procedures outlined in the development of AZ Germ Salt II (Crop Science vol. 29:0493 (1989)) and AZ90NDC ST (Crop science vol. 31, p 1098 (1991)). The modification being that the two procedures were used in tandem, with increasing levels of salinity for each successive generation.
Phenotypic recurrent selection was used Final selections were made from greenhouse plants subjected to germination and post-germination salt stress.
Parentage traces to Mesa Sirsa (506/) and other non dormant experimental cu1tivars (50%).
Approximate germplasm source contributions are:
M. falcata (0%), Ladak (0%), M. varia (0%), Turkistan (0%), Flemish (0%), Chilean (0%), Peruvian (0%), Indian (50%), African (0%), Arabian (0%) and unknown (50%). Breeder seed (Syn 1) was produced under field isolation near Kingsburg, CA in 1994.
2. Area of intended use is Central and Southern California, and the lower elevations of Arizona and New Mexico. Area of adaptation is southwest regions of U.S.
3. Fall dormancy is similar to Cuf 101. Flower color is approximately 98% purple and 1% variegated with less than 1% yellow, 0% cream and white.
4. Salado has high resistance to Fusarium wilt, blue alfalfa aphid, and southern root knot nematode; resistance to spotted alfalfa; moderate resistance to pea aphid, stem nematode and lepto leaf spot; low resistance to anthracnose (race 1) and Phytophthora root rot, tolerant to salt (NaCl) at germination; and tolerant for forage production under salt (NaCl) dress; and susceptible to Verticillium wilt. Salado has not been tested for resistance to bacterial wilt, aphanomyces and other species of root knot nematode.
5. Seed increase is limited to one generation each of breeder (Syn 1), foundation (Syn 2) and certified (Syn 3) seed classes. Certified may be produced from cither breeder or foundation classes. A 1, 3 and 5 year stand life is permitted on fields producing breeder, foundation and certified classes, respectively. Foundation seed production, outside the area of adaptation is limited to single-season production (non-overwintering). Second year of production may be allowed with inspection and approval by breeder prior to second year production. Breeder seed was produced in 1993. ABI will maintain sufficient stocks for the projected life of the variety.
6. Certified seed will be available in 1998
7, Plant variety protection has been applied for.
