1. Achieva is a synthetic variety with 200 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. Achieva traces to a cross between a population derived from Jewel and 3 year old Wisconsin nursery selections tracing to the varieties DK122, Crown II, and Multiplier. Approximate germplasm source contributions are: M. falcata -5%, Ladak -6%, M. varia -28%, Turkistan -3%, Flemish -52% and Chilean -6%.
2. Achieva is adapted to and intended for use in the northern and central U.S. for hay, haylage, greenchop or dehy production. It has been tested in Idaho, Wisconsin, Minnesota, Missouri, Pennsylvania and New York.
3. Achieva is a dormant variety. Fall dormancy is similar to Ranger. Flower color is 85% purple, 15% variegated and a trace of white, yellow and cream. At first flower in autumn approximately 86% of the plants show multifoliolate expression.
4. Achieva has high resistance
to anthracnose (race 1), Fusarium wilt, and Phytophthora root rot with
resistance to spotted alfalfa aphid, pea aphid, bacterial wilt, Aphanomyces
root rot (race 1) and Verticillium wilt. It has moderate resistance to
stem nematode.
Reaction to blue alfalfa aphid
has 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.
