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--CW5 AN3 (8), Cherokee (2), Lahontan (2), PI206452
(2), Glory (1), Thor (1), Vernal (1), Everest (1), MNBI1(4), MNP--01 (4),
MNP42 (6), California Line (M. sativa, E. H. Stanfrod) (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, winter hardiness, 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 Midwest states (WI, MI, MN, IA, IL, etc.). The primary purpose will be for hay, green chop 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, and Fusarium wilt. It has moderate resistance to anthracnose, Verticillium wilt, stem nematode and spotted alfalfa aphid and low resistance to Aphanomyces (Race 1). Not tested for blue alfalfa aphid or pea aphid.
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 will be available spring of 1988.
7. Application for the Plant Variety Protection is undecided.
