1. Resistar is a 400-clone synthetic variety. Parent clones were selected for resistance to one or more of the following diseases: anthracnose (race 1), Phytophthora root rot, and Verticillium wilt. Parent clones trace to the varieties Arrow, Centurion, Dart, Sparta, and Verta +. Estimates of germplasm sources are: M. falcata (5%), Ladak (5%), M. varia (21%), Turkistan (12%), Flemish (46%), Chilean (7%), Peruvian (2%), unknown (2%).
2. Resistar is adapted to and intended for use as hay, haylage, greenchop, and dehydration from the upper midwest through the mid-south production areas. It has been tested in Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Pennsylvania, Ohio and Wisconsin.
3. Resistar is a moderately dormant variety, similar to Saranac. Flower color is approximately 86% purple, 14% variegated, and a trace of cream, yellow, and white.
4. Resistar is highly resistant to Fusarium wilt, Verticillium wilt, and Phytophthora root rot; resistant to anthracnose (Race 1), stem nematode, and bacterial wilt; and moderately resistant to spotted alfalfa aphid. It has not been tested for reaction to pea aphid or blue alfalfa aphid.
5. Seed increase is limited to
one generation of breeder (syn 1), and two generations each of foundation
(syn 2 or 3) and certified (syn 3 or 4) classes. Breeder seed was produced
in isolation in Washington sufficient for the life of the variety, and
will be maintained in cold storage in separate lots by FFR Cooperative.
Length of stand for
breeder seed is two years, three
years for foundation seed production, and six years for certified production.
Breeder and foundation seed production are limited to the northwestern
United States.
6. Certified seed will be available in 1991.
7. Application will not be made for Plant Variety Protection.
8. Information in this application may be turned over to the PVP office.
