1. CW 89132 is a
synthetic variety with 320 parent plants which were selected for aphid
resistance, drought tolerance, frost tolerance, persistence and
agronomic characteristics from space planted nurseries and yield trials
in Argentina. Parent plants were selected from various populations which
were developed by a combination of phenotypic recurrent selection and
strain crossing with selection for resistance to one or more of the
following pests: Fusarium wilt, Verticillium wilt, Phytophthora root
rot, anthracnose (race 1), spotted alfalfa aphid, blue alfalfa aphid,
and stem nematode. Parentage of CW 89132 traces to DK 191, Super
Supreme, F969, 5929, ACA 900, Grasis II, Beacon, and miscellaneous
Ca1/West Seeds breeding
populations. Approximate germplasm source contributions are as follows:
M. varia (5%), Turkistan (15%), Flemish (5%), Chilean (9%), Peruvian
(4%), Indian (25%), and African (37%). 2. CW 89132 is adapted
to and intended for use in the Southwest area of the U.S. and Argentina.
CW 89132 has been tested in California and Argentina. 3. CW 89132 is a very
nondormant variety with fall dormancy
similar to FD class 9 check varieties. Flower color observed in the Syn.
2 generation is greater than 99% purple with a trace of variegated,
white, cream, and yellow. 4. CW 89132 has high
resistance to anthracnose (race 1), Fusarium wilt, Phytophthora root
rot, pea aphid, spotted alfalfa aphid, blue alfalfa aphid, stem
nematode, and southern root knot nematode (Meloidogyne incognita),
with 5. Seed increase of CW
89132 is on a limited generation basis with one generation of breeder
and two generations of the foundation and certified seed classes.
Breeder (Syn. l), 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 Mendoza, Argentina in 1998. 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
89132 will be available in 2003. 7.
No decision bas been made regarding Plant Variety Protection. 8. This information can
