Stampede
1. Stampede is a synthetic variety with 228 parent clones. One hundred twelve parents were selected out of three year old forage yield plots for the deep set crown trait. This source material traces back to Answer, Apollo, and Dairyland experimentals. Dairyland experimentals trace back to Ranger and Vernal. One hundred sixteen parents were selected out of disease nurseries in Clinton and Marshfield, Wisconsin. This source material traces back to RamRod, ProCut II, Aggressor, Legacy, Precedent, Blazer XL, Starmaster, Zenith, DK122, Answer, MNP-D1, and Webfoot. Parent plants of the two germplasrns were interplanted in cage isolation to produce Breeder seed. The percent of germplasm sources are Ladak(25), M.varia(15), Turkistan(25), and Flemish(40).
2. Stampede is adapted to the North Central, East Central, and Great Plains regions of the United States. It is intended for use in the Central and Northern half of the United States. The states in which it has been tested are: Wisconsin, Kansas, New York, and Pennsylvania.
3. Stampede similar to Ranger in fall dormancy. Flower color in the Syn.2 generation is 88% purple, 12% variegated, and trace amounts of cream, white, and yellow. Stampede has a deeper set crown than Magnum III, Alfagraze, and Vernal.
4. Stampede has high resistance to Phytophthora root rot, bacterial wilt, spotted alfalfa aphid, resistance to Fusarium wilt, Verticillium wilt, anthracnose (Race 1), pea aphid, Aphanomyces root rot (Race 1) and stem nematode. Its reaction to northern root-knot nematode and blue alfalfa aphid have not been tested.
5. Breeder seed was produced from bulking seed of parent plants planted in cage isolation to produce Syn.1 at Sloughouse, CA in 1991. Foundation seed (Syn.2) was produced from Breeder seed and Certified seed (2 or 3) from either Breeder or Foundation seed. One generation each of Breeder and Foundation, and two generations of Certified seed (Syn.2 or 3) classes are recognized. A maximum of three years each is permitted on stands producing Breeder and Foundation seed with five years for Certified seed. Sufficient Breeder seed for the projected life of the variety will be maintained by Dairyland Research.
6. Certified seed will be available spring of 1995.
7. Application for Plant Variety Protection is undecided.
