1. WL 535HQ is a 163-plant synthetic variety resulting from a cross between two elite experimental
lines. Source material traces to WL 320, WL 457, WL 512, WL 450, and WL 451. Approximate
germplasm source contributions are Arabian (24%), African (30%), Indian (10%), Chilean (16%),
Turkistan (8%), Flemish (6%), Ladak (30/6), and M. varia (3%).
2. WL 535HQ is adapted to and intended for use in the southwestern United States. W320 has been
tested in California.
3. Flower color of WL 535HQ at syn2 approximates 100% purple with a trace of variegated. The
fall dormancy of WL 535HQ is similar to Pierce (Class 8)
4. WL 535HQ has high resistance to Fusarium. wilt, Verticillium wilt, Phytophthora root rot, and
spotted alfalfa aphid; and resistance to stem nematode and southern root knot nematode. Reaction to
anthracnose (race 1), bacterial wilt, blue alfalfa aphid, pea aphid, northern root knot nematode, and
Aphanomyces root rot (race 1) has not been adequately tested.
5. Breeder seed (syn1) was produced in 1996 on 163 plants under cage isolation at Warden,
Washington. Sufficient foundation (syn2) seed will be produced for the expected life of the variety and
will be maintained by W-L Research. One generation of breeder (syn1), two generations of foundation
(syn2 or 3) and three generations of certified (syn2, 3 or 4) seed are recognized. The maximum permitted
length of stand for foundation and certified seed fields are three and five years, respectively. Production
of syn3 foundation seed requires consent of the breeder.
6. Certified seed will be marketed in 2000.
7. It is undecided whether application will be made for Plant Variety Protection.
8. The information in this application can be turned over to the PVP office.
