to Apollo (11%),
NAPB 35 (11%), Apollo Supreme
(9%), Krasnodarskaja Ranniaja (6%), Duke, Raidor and NCW-21 (4% each),
Dart, Anchor, WL 318, WL 220, Sabilt, Europe, NCCR-1, MSEFP6Sn3W3P3, Apollo
II, Atlas, Mercury, Advantage and Trident (2% each), with 25% from numerous
other sources. Approximate germplasm source contribution are: M.
falcata (7%), Ladak (6%), M. varia (21%), Turkistan (16%), Flemish
(30%), Chilean (11%), Peruvian (3%) and 6% unknown.
2. Cutter is intended for use in the North Central and Northeastern U.S. for hay, haylage, greenchop or dehy production. It has been tested in Iowa, Idaho and Wisconsin.
3. Fall dormancy is similar to Saranac. Flower color is approximately 73% purple and 27% variegated, with a trace of white, yellow and cream.
4. Cutter has high resistance to Phytophthora root rot and Fusarium wilt; resistance to Verticillium wilt, bacterial wilt, anthracnose, spotted alfalfa aphid and pea aphid; and moderate resistance to Aphanomyces and stem nematode. Reaction to blue alfalfa aphid has not been determined.
5. Seed increase is limited to one generation each of breeder, foundation and certified 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.
6. Certified seed will be available in 1990.
