DS9802
1. DS9802 is a 20 clone synthetic variety. One half of the parent plants were selected out offorage yield plots near Marshfield, Wisconsin, for resistance to Phytophthora root rot, bacterialwilt, Fusarium wilt, Aphanomyces root rot; crowns free of crown rot and expression of branchroots. The other half of the plants were selected out of forage yield trials near Clinton,Wisconsin. 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, andiracnose (race 1), Verticillium. wilt, Aphanomyces root rot (race 1),and spotted alfalfa aphid Germplasm sources are: 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 and east central region of theUnited States. The states where it has been tested are Minnesota, Indiana, and Wisconsin.
3. DS9802 is a dormant variety similar to the fall dormancy 3 check. Flower color in the syn2generation is 85% purple, 15% variegated with trace amounts of crean-4 white and yellow.
4. DS9802 has high resistance to bacterial wilt, Fusarium wilt, Phytophthora root rot andnorthern root-knot nematode; resistance to Aphanomyces root rot (race 1), pea aphid, stemnematode, Verticillium wilt and anthracnose (race 1). It has not been tested for spotted alfalfaaphid and blue alfalfa aphid.
5. Breeder seed (syn1) was produced from bulking seed of field isolated parent 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 are recognized. A maximum of three years each is permitted on standsproducing breeder and foundation seed with five years for certified seed. Sufficient breeder seedfor the Projected life of the variety will be maintained by Dairyland Research International.
6. Certified Seed was available fall of 1999.
7. Application for the Plant Variety Protection is undecided.
