XGrazer


  1. XGrazer has 358 parent plants all tracing to the experimental variety ABI 9022. ABI 9022 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 358 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.  The % of the germplasm sources listed below contribute to the major genetic constitution of this variety.

2. XGrazer 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 XGrazer is similar to Vernal. Flower color is approximately 67% purple and 32% variegated with a trace of cream, white and yellow. Tolerance to intensive grazing is similar to Alfagraze.

4. XGrazer has high resistance to bacterial wilt, fusarium wilt, verticillium wilt, anthracnose (race 1) and phytophthora root rot, resistance to aphanomyces root rot (race 1), moderate resistance to stem nematode, and low 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 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 projected life of the variety

6. Certified seed will be available in 1997

7. Plant Variety Protection will not be applied for.
