1. LM 459 was developed by two cycles of phenotypic recurrent selection from a population created by intercrossing selected plants from Deseret, GT58, Resis, and FSRC expenmental lines F429, H-131, F-133, 11-134, F-146, H-154 and H-156. Selection criterion were resistance to bacterial wilt, Fusazium wilt, Phytophthora root rot, and stem nematode. Approximately 2000 second cycle selections were intererossed to produce the Syn. 1 generation. Estimated germplasm sources are M. falcata (1%), Ladak (2%), M. varia (16%), Turkistan (18%), Flemish (37%), Chilean (10%), Peruvian (2%) and unknown (14%).
2. LM 459 is adapted to and intended for use in the western region of the US where moderately dormant varieties are grown. It has been tested in CA, IN and NM.
3. LM 459 is a moderately dormant variety with fail dormancy similar to DuPuits. Rower color of the Syn.2 generation is approximately 92% purple, 6% variegated, and 2% white with a trace of cream and yellow.
4. LM 459 has high resistance to Fusarium wilt, and pea aphid; resistance to bacterial wilt, Verticillium wilt, stem nematode, spotted alfalfa aphid, Phytophthora root rot and southern root knot nematode (M. incognita); moderate resistance to blue alfalfa aphid; low resistance to anthracnose (Race 1) and northern root knot neinatode (M. hapla); and is susceptible to Aphanomyces root rot (Race 1).
5. Breeder seed (Syn. 1) was produced in 1985 and 1986 in an open isolation and bulked with a sufficient quantity held in storage for the expected life of the variety. Seed increase is on a three generation basis with a 2, 3 and 6 year stand life permitted for breeder seed (Syn. 1), foundation (Syn. 2) and certified (Syn 3) seed classes, respectively. Breeder seed production is limited to CA, with foundation and certified seed production limited to CA, WA, OR or ID. Breeder seed will be maintained by FSRC and Lobse Mill Inc.
6. Certified seed will be available in 1994.
7. No application will be made for Plant Variety protection.
