1. ZG 9415 has 368 parent plants all tracing to the variety A-295.
A-295 was seeded into replicated grazing trials near Warrensburg, MO in
March of 1991. Plots were grazed continuously for 70 days in 1991 and 155
days each in 1992 and 1993. In October of 1993 when stands had declined
to about 10% plots were dug with the healthiest plants having large symmetrical
crowns saved. Breeder seed (syn 1) was produced in the greenhouse on the
original 368 plants and harvested in bulk in the spring of 1994. Additional
breeder seed was produced in the field near Nampa, ID in 1994 from the
original parent plants and approximately 15 cuttings of each clone transplanted
at random and harvested in bulk.

2. ZG 9415 appears to be adapted to and is intended for use in the North Central Region of the U.S. It is intended for use as a grazing crop as well as for making stored feed.
3. Fall dormancy of ZG 9415 is similar to Vernal. Flower color is approximately 65% purple and 34% variegated with a trace of cream, white and yellow. Tolerance to intensive grazing is similar to Alfagraze.
4. ZG 9415 has high resistance to bacterial wilt, fusarium wilt, anthracnose (race 1) and phytophthora root rot and resistance to verticillium wilt, stem nematode and aphanomyces root rot (race 1) and moderate resistance to pea aphid. It has not been tested for reaction to spotted alfalfa aphid, blue alfalfa aphid and 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 seed may be produced from either breeder or foundation classes. A 1, 3 and 6 year stand life is permitted on fields producing breeder, foundation and certified seed classes respectively. Foundation seed production is limited to the Pacific Northwest. Breeder seed was produced in 1994. ABI will maintain sufficient seed stocks for the life of the variety.
6. Certified seed will be available in 1997.
7. Plant variety protection will not be applied for.
