1. LM 456 (experimental designation IH-171) is a broad based population originating from 2420 plants phenotypically selected from a disease-stem nematode nursery near Hollister, California. Parentage Traces to IH 101R (19), Trumpetor (172), Pike (42), WL 318 (79), WL 316 (131), AS 49R (168), LM 455 (65) and 10 PSRC experimental lines (1648). Selected plants were intercrossed in an open isolation near Hollister, California in 1985 and 1986 with Syn. 1 generation designated as breeder seed.
2. LM 456 is adapted to and intended for use in the western region of the United States where moderately dormant varieties are grown. It has been tested in the Sacramento and San Joaquin valleys of California; eastern counties of Oregon; Nevada and New Mexico.
3. LM 456 is a moderately dormant variety with fall dormancy similar to Deputies. Flower color observed in the Syn. 2 generation is approximately 90% purple, 1% yellow, 2% white, 7% variegated.
4. LM 456 has high resistance to blue alfalfa aphid, with resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, Phytophthora root rot, stem nematode and southern root knot nematode (M. incognita), with moderate resistance to Verticillium wilt, pea aphid, and spotted alfalfa aphid. LM 456 has not been tested for resistance to Aphanomyces root rot (race 1).
5. Seed increase of LM 456 is on a limited generation basis with two generations of breeder, foundation, and certified seed classes. Breeder (Syn. 1), foundation (Syn. 2 or Syn. 3), and certified classes (Syn. 3 or Syn. 4) classes will be recognized. Breeder seed was produced under open isolation at Hollister, California in 1985 and 1986. Sufficient foundation seed for the projected life of the variety will be maintained by Lohse Mill, Inc. Stands of foundation and certified seed fields are limited- to 3 and 6 years, respectively. Areas for seed production are limited to California, Oregon, Washington and Idaho.
6. Certified seed of LM 456 will be available in 1997.
7. No decision has been made regarding Plant Variety Protection.
