89783

1. 89783 is a synthetic variety tracing to line crosses of four experimental lines that had phenotypic recurrent selection for anthracnose, Aphanomyces, bacterial wilt, Fusarium wilt, Phytophthora root rot, stem nematode, and Verticillium wilt. Parentage traces to Apollo II, Commandor, NC83-1, Drummor, Armor, NCMP1, NCMP10 and DK 135. Estimates of the major germplasm sources are M. falcata (7%), Ladak (4%), M. varia (16%), Turkistan (2%), Flemish (17%), Chilean (1%), and unknown (53%).

2. 89783 is intended for use in and adapted to the Northeast, North Central, Central, and Pacific Northwest U.S. and E. Canada for hay, haylage, and dehydration purposes. It has been tested in Wisconsin, Washington, Minnesota, and Ontario.

3. Flower color of 89783 at full bloom is 69% purple and 31% variegated with a trace cream, white and yellow. Its fall dormancy is similar to Ranger.

4. 89783 has high resistance to Verticillium wilt; resistance to anthracnose (Race 1), Phytophthora root rot, bacterial wilt, pea aphid, Fusarium wilt and to Aphanomyces (Race 1); and is susceptible to blue aphid.

5. Breeder seed (Syn 1) was produced in cage isolation near Woodland, CA in 1988. Seed increase is limited to one generation of breeder seed (Syn 1), two generations of foundation seed (Syn 2 or 3), and two generations of certified seed (Syn 3 or 4). Sufficient foundation seed for the life of the variety will be maintained by Northrup King Company. Production of Syn 3 foundation seed requires the consent of the breeder. Stands of foundation and certified seed fields are limited to 3 and 5 years, respectively.

6. Certified seed will be available in 1991.

7. A decision on Plant Variety Protection has not been made.
