1. ZG 9533 has 166 parent plants tracing to the variety Imperial. Imperial was seeded into replicated plots at Eatonton, GA in October 1990. Plots were grazed continuously for 152 days n 1991. Plots were dug n Nov. 1991 with the healthiest plants with large symmetrical crowns saved and pollinated. In October 1992 replicated plots were planted with the cycle seed at Fatonton, GA and grazed continuously for approximately 150 days n 1993 and 1994. In November of 1994 plots were dug and plants saved on the same basis as in 1991. Breeder seed (Syn 1) was produced in the greenhouse on the orginal 166 plants and harvested in bulk in the spring of 1995. Addtional breeder seed was produced in the field near Nampa, ID in 1995 from approximately 25 cuttings of each clone transplanted at random and harvested in bulk.

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 ether breeder or foundation . A 2,3 and 6 year stand life s permitted on fields producing breeder. Foundation and certified seed class respectively. Foundation seed production is limited to the Pacific Northwest Breeder seed was produced n 1995. ABI will maintain sufficient seed stocks for the life of the variety.
