1. CW 95026 is a
synthetic variety with 225 parent plants that were selected sequentially
for multifoliolate leaf expression and for resistance to Phytophthora
root rot and anthracnose (race 1). Parent plants were selected from
crosses between selections from three-year old Minnesota and Wisconsin
yield trials and three-year old nursery selections, and from crosses
between the selections from three-year old Wisconsin nurseries. Both
yield trial and nursery source varieties were derived from various
populations that were developed by phenotypic recurrent selection for
high relative feed value (using Near Infrared Reflectance Spectroscopy),
and for resistance to one or more of the following pests: bacterial
wilt, Fusarium Wilt, Verticillium wilt, Phytophthora root rot,
Aphanomyces root rot (race 1), anthracnose (race 1), and
Leptosphaerulina leafspot. Parentage of CW 95026 traces to the following
germplasm sources: 512, Gold Plus, and miscellaneous Ca1/West Seeds
breeding populations. Approximate germplasm source contributions are as
follows: M. falcata (8%), Ladak (5%), M. varia (24%), Turkistan (3%),
Flemish (51%), and Chilean (9%). 2. CW 95026 is adapted
to and intended for use in the North Central, East Central, and Great
Plains areas of the U.S. CW 95026 has been tested in Wisconsin,
Minnesota, Iowa, Pennsylvania, and Nebraska, 3. CW 95026 is a
dormant variety with fall dormancy similar to FD class 5 check
varieties. Flower color observed in the Syn. 2 generation is
approximately 100% purple, with a trace of variegated, cream, white, and
yellow. 4. CW 95026 has high resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, Phytophthora root rot, Aphanomyces root rot (race 1), and stem nematode with resistance to Verticillium wilt, pea aphid, spotted alfalfa aphid, and northern root knot nematode (Meloidogyne hapla. Reaction to blue alfalfa aphid has not been adequately tested. 5.
Seed increase of CW 95026 is on a limited generation basis with one
generation of breeder and two generations of the foundation and
certified seed classes. Breeder (Syn. 1), foundation (Syn. 2 or Syn. 3),
and certified (Syn. 3 or Syn. 4) classes will be recognized. Production
of Syn. 3 foundation seed requires consent of the breeder. Breeder seed
was produced under cage isolation near Woodland, California in 1999.
Sufficient foundation seed for the projected life of the variety will be
maintained by Cal/West Seeds. Stands of foundation and certified seed
fields are limited to 3 and 6 years, respectively. 6. Certified seed of CW
95026 will be available in 2003. 7. No decision has been
made regarding Plant Variety Protection. 8. This information can
be forwarded to the PVP office. 9.
