DSS5106
1. DSS5106 is a 16 clone synthetic variety. Parent clones were selectedout of forage yield plotsand/or disease nurseries. These parent plants wereprogeny tested for one or more of thefollowing traits: forage yield, standpersistence, forage quality, maturity, resistance to bacterialwilt, Fusariurnwilt, Phytophthora root rot, anthracnose (race 1), Verticillium wilt, Aphanomycesroot rot (race 1), and spotted alfalfa aphid. Parent plants trace back toTempo, Apollo Supreme,Thor, WL312, Answer, Teweles Multistrain, and DairylandExperimentals which trace back toRanger and Iroquois. Germplasm. sourcesare:Turkistan (32%), Flemish (40%) and Chilean(28%).
2. DSS5106 is adapted in the north central and Great Plains regions ofthe United States. It isintended for use in the north and central regionofthe United States. The states in which it hasbeen tested are: Wisconsin,Nebraska,Kansas, and Oklahoma.
3. DSS5106 is moderately dormant, fall dormancy 4 variety. Flower colorin the syn2 generationis 90% purple, 10% variegated, and trace amounts ofcream, white, and yellow.
4. DSS5106 has high resistance to Phytophthora root rot, bacterial wilt,Fusarium wilt, northernroot-knot nematode (M. hapla); resistance to Verticilliumwilt, pea aphid, anthracnose (race 1);moderate resistance to stem nematodeand Aphanomyces root rot (race 1). Its reaction to spottedalfalfa aphid andblue alfalfa aphid have not been tested.
5. Breeder seed was produced from cuttings of the parent plants plantedin cage isolation toproduce syn1 seed at Sloughhouse, California, in 1988-90.Seed was bulkedin equalproportions each year and lots were kept separate.Foundation seed (syn2)was produced from breeder seed and certified seed (syn2or 3) from either breeder or foundationseed. One generation each of breederand foundation, and two generations of certifiedseed classes arerecognized.A maximum of three harvest years each is permitted on standsproducingbreederand foundation seed with five years for certified seed. Sufficientbreederseed for the projected life of the variety will be maintained by DairylandResearchInternational.
6. Certified seed will be available spring of 1999.
7. Application for Plant Variety Protection is anticipated.
