1. K93 is a synthetic variety
with about 100 parent plants. Parent plants were selected from vigorous
progeny rows and resistance to one or more of the following pests: Verticillium
wilt, Phytophthora root rot and Aphanomyces. The following germplasm sources
were used in the development of GG93: Wrangler, Impact, and Renegade. Approximate
germplasm source contributions
are: M. falcata -6%, Ladak -6%, M.varia -21%, Turkistan
-39%, Flemish -20%, Chilean -5%, Peruvian -1%, and Unknown -2%.
2. K93 is a dormant variety adapted to the northern region of the U.S. It has been tested in Minnesota, Wisconsin, Nebraska, Michigan and Illinois. It will be marketed primarily in these states.
3. Approximately 70% of the flowers (Syn. 2) are purple, 30% variegated, with a trace of yellow or cream. Fall dormancy is similar to Ranger.
4. K93 has resistance to bacterial
wilt, Phytophthora root rot, Fusarium wilt, pea aphid, and Verticillium
wilt. It has moderate resistance to stem nematode. It has low resistance
to Aphanomyces (race 1). It has not been adequately tested to determine
its reaction
to anthracnose and root knot
nematode.
5. Sufficient breeder seed was
produced and will be maintained by Green Genes, Inc. near Adrian, OR under
controlled environmental conditions to last the life of the variety. One
generation each of breeder (Syn 2), foundation (Syn 3), and certified (Syn
3 or 4) is
recognized. Up to 2 harvest
years are permitted on stands producing foundation seed with 6 years allowed
on certified production. Foundation seed production will be permitted
in Nevada, Oregon, or Idaho. There are no restrictions on area of production
of certified seed.
6. Certified seed will be marketed in the fall of 1993.
7. Application for Plant Variety Protection is not anticipated.
