DS9802
1. DS9802 is a 20 clone synthetic variety. One half of the parent plantswere selected out offorage yield plots near Marshfield, Wisconsin, for resistanceto Phytophthora root rot, bacterialwilt, Fusarium wilt, Aphanomyces rootrot; crowns free of crown rot and expression of branchroots. The other halfof the plants were selected out of forage yield trials near Clinton,Wisconsin.These parent plants were progeny tested for one or more of the followingtraits:forage yield, stand persistence, forage quality, resistance to bacterialwilt, Fusarium wilt, Phytophthora root rot, andiracnose (race 1), Verticillium.wilt, Aphanomyces root rot (race 1),and spotted alfalfa aphid Germplasm sourcesare: Ladak (9%), M. varia (28%), Turkistan (18%),Flemish (28%), and unknown(17%).
2. DS9802 is adapted to and intended for use in the north central andeast central region of theUnited States. The states where it has been testedare Minnesota, Indiana, and Wisconsin.
3. DS9802 is a dormant variety similar to the fall dormancy 3 check. Flowercolor in the syn2generation is 85% purple, 15% variegated with trace amountsof crean-4 white and yellow.
4. DS9802 has high resistance to bacterial wilt, Fusarium wilt, Phytophthoraroot rot andnorthern root-knot nematode; resistance to Aphanomyces root rot(race 1), pea aphid, stemnematode, Verticillium wilt and anthracnose (race1). It has not been tested for spotted alfalfaaphid and blue alfalfa aphid.
5. Breeder seed (syn1) was produced from bulking seed of field isolatedparent plants near Sloughhouse, California, in 1993. Foundation seed (syn2)was produced from breeder seed andcertified seed (syn3) from foundation seed.One generation each of breeder,. foundation andcertified seed classes arerecognized. A maximum of three years each is permitted on standsproducingbreeder and foundation seed with five years for certified seed. Sufficientbreeder seedfor the Projected life of the variety will be maintained by DairylandResearch International.
6. Certified Seed was available fall of 1999.
