1. Magnum III is a synthetic variety developed by Dairyland Research International, Clinton, WI. The percent of germplasm sources are M. falcata (5), Ladak (4), M. varia (27), Turkistan (31), Flemish (26), and Chilean (7). Parental clones trace back to Iroquois (9), MSB--CW5AN3 (8), Cherokee (2), Lahontan (2), PI206452 (2), Glory (1), Thor (1), Vernal (1), Everest (1), MNB1 (4), MNP--D1 (4), MNP42 (6), California Line (M. falcata, E. H. Stanford) (4), and Teweles Multi--strain (origin unknown) (8). Parental clones were selected based on progeny tests for one or more of the following traits: forage yield, stand persistence, winterhardiness, seed yield, and resistance to bacterial wilt, Phytophthora root rot, Fusarium wilt, anthracnose, and Verticillium wilt.
2. Magnum III has been tested in Wisconsin, Iowa, Minnesota, and South Dakota. It will be marketed in the Midwest states (WI, MI, MN, IA, IL, etc.). The primary purpose will be for hay, greenchop, and dehydration.
3. Flower color is 82% purple, 17% variegated and less than 1% yellow, cream, and white. Fall dormancy is moderately dormant similar to Saranac.
4. This variety has resistance to bacterial wilt, Phytophthora root rot, Fusarium wilt, and pea aphid. It has moderate resistance to anthracnose (Race 1), Verticillium wilt, stem nematode, blue alfalfa aphid, and spotted alfalfa aphid and low resistance to Aphanomyces root rot (Race 1).
5. Breeder seed has been produced from cuttings of the parental clones in a cage as Syn. 1. Breeder seed (Syn. 1) was grown for the expected life of the variety and will be kept separate from year to year. Foundation seed will be produced from Breeder seed and Certified seed either from Breeder or Foundation seed. One generation each of Breeder, Foundation, and Certified seed class is recognized. A maximum of three years each is permitted on stands producing Breeder and Foundation seed with five years for Certified seed.
6. Certified seed was available spring of 1988.
7. Application for the Plant Variety Protection is undecided.

protection, information included with this application may be provided
