LASER
1. Laser is a 17 clone synthetic variety. Parent plants were selected out of forage yield plots and/or disease nurseries. These parent plants were progeny tested for one or more of the following traits: forage yield, stand persistence, forage quality, resistance to bacterial wilt, Fusarium wilt, Phytophthora, root rot, anthracnose (race 1), Verticillium wilt, Aphanomyces root rot (race 1), and spotted alfalfa aphid. Parent plants trace back to Tempo (1), Thor (1), Answer (1), Apollo (1), MNP-D1 (1), MNP-B1 (syn2) (1), NCMP-2 (1), Teweles Multistrain (5), and Dairyland experimentals (5) which trace back to Vernal, Ranger, and Iroquois. Germplasm sources trace back to Turkistan (30%), Flemish (60%), and Chilean (10%).
2. Laser is adapted to the north central and Great Plains regions of the United States. It is intended for use in the central and northern United States. The states in which it has been tested are: Wisconsin, Iowa, Kansas, and Minnesota.
3. Laser is similar to Saranac in fall dormancy. Flower color in the syn2 generation is 85% purple, 15% variegated, with trace amounts of cream, white and yellow.
4. Laser has high resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot, resistance to anthracnose, Verticillium wilt moderate resistance to Aphanomyces root rot (race 1), spotted alfalfa aphid, blue alfalfa aphid, stem nematode, pea aphid and northern root-knot nematode.
5. Breeder seed was produced from cuttings of the parental plants in an isolation block as syn1 in Sloughhouse, California, in 1990-1992. Seed was bulked in equal proportions each year, and lots were kept separate. Foundation seed (syn2) was produced from breeder seed and certified seed (syn2 or 3) from either breeder or foundation seed. One generation each pf breeder and foundation, and two generations of certified seed (syn2 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 International.
6. Certified seed will be available spring of 1995.
