86-142
(Experimental Desig.)

1.   86-142 is a synthetic variety resulting from an intercross between anthracnose resistant plants of two multiple pest-resistant experimental lines. Both lines were developed through recurrent phenotypic selection for resistance to bacterial wilt, Verticillium wilt, Phytophthora root rot, and spotted alfalfa aphid. Subsequent selection for anthracnose resistance resulted in 246 survivors (Line A=125, Line B=121) which were crossed in an isolation cage. Parental germplasm traces primarily to Vernal, Saranac, Ranger, and Vertus, with lesser contributions from Team and Grimm. Approximate germplasm source contributions are: M. falcata - 8%, Ladak - 9%, M. varia - 32%, Turkistan - 9%, Flemish - 38%, and Chilean - 4%.

2.   86-142 is a fall dormant variety adapted for use in the northern half of the U.S. for hay, haylage, and dehydration purposes. It has been tested for yield in NY, PA, WI, IL and WA.

3.  Flower color of 86-142 at full bloom is approximately 97% purple and 3% variegated with traces of cream and yellow. Fall dormancy of 86-142 is similar to that of Ranger.

4.   86-142 has high resistance to bacterial wilt, Fusarium wilt, anthracnose (Race 1), and Phytophthora root rot; resistance to Verticillium wilt, pea aphid, and spotted alfalfa aphid; and moderate resistance to stem nematode and northern root knot nematode. Reaction to blue alfalfa aphid has not been adequately tested.

5.   Breeder seed (Syn 1) was produced on 246 plants under cage isolation at Bakersfield, CA. Sufficient Foundation (Syn 2) seed is being produced near Warden, WA for the expected life of the variety. One generation of Breeder (Syn 1), and two generations each of Foundation (Syn 2 or 3) and Certified (Syn 3 or 4) seed are recognized. The maximum permitted length of stand for Foundation and Certified seed fields are 3 and 5 harvest years, respectively. Foundation seed must be produced above 40 degrees north latitude. Production of Syn 3 Foundation seed requires consent of the breeder.

6.   Certified seed will be marketed in 1989.

7.   It is undecided whether application will be made for Plant Variety Protection.

8.   The information in this application is available to the PVP office.
