1. Jewel is a synthetic variety
with 56 parent plants. Parent plants were selected for multifoliolate expression
and resistance to one or more of the following pests: bacterial wilt, Verticillium
wilt, anthracnose, Phytophthora root rot, Aphanomyces root rot,
Leptosphaerulina leaf spot and
spotted alfalfa aphid. The following germplasm sources were used in the
development of Jewel: Precedent, VS-775, Pro-Cut 2, DK122, and 2833. Approximate
germplasm source contributions are: M. falcata -4%, Ladak -6%, M.
varia -26%, Turkistan -3%, Flemish -55% and Chilean -6%.
2. Jewel is adapted to and intended for use in the northern U.S. for hay, haylage, greenchop or dehy production. It has been tested in Idaho, Wisconsin, Minnesota, Missouri, Pennsylvania, and New York.
3. Jewel is a moderately dormant variety. Fall dormancy is similar to Saranac. Flower color is 90% purple, 10% variegated and a trace of white, yellow and cream. At first flower in autumn approximately 85% of the plants show some multifoliolate expression.
4. Jewel has high resistance to bacterial wilt and Phytophthora root rot with resistance to spotted alfalfa aphid, pea aphid, Fusarium wilt, anthracnose (race 1), and Verticillium wilt. It has moderate resistance to Aphanomyces root rot (race 1). Reaction to stem nematode and blue alfalfa aphid have not been tested.
5. Seed increase is on a limited
generation basis with one generation of breeder and two generations of
foundation and certified seed classes. Breeder (Syn 1), foundation (Syn
2 or Syn 3), and certified (Syn 3 or Syn 4) classes will be recognized.
Production of Syn 3
foundation seed requires the
consent of the breeder. Breeder seed was produced under cage isolation
at Woodland, California. Sufficient foundation seed for the projected life
of the variety will be maintained by VISTA. Stands of foundation and certified
seed fields
are limited to 3 and 6 years,
respectively.
6. Certified seed will be marketed in 1992.
7. No decision has been made concerning Plant Variety Protection.
