1. CW 99113 is a
synthetic variety with 77 parent plants which were selected for lygus
tolerance and seed yield from space planted nurseries in California.
Parent plants were selected from various populations which were
developed by selecting for aphid resistance, drought tolerance, frost
tolerance, persistence and agronomic characteristics from space planted
nurseries and yield trials in Argentina. Parentage of CW 99113 traces to
miscellaneous Cal/West Seeds breeding populations (100%). Approximate
germplasm source contributions are as follows: M. varia (4%), Turkistan
(10%), Flemish (4%), C1i1ean (9%), Peruvian (4%), Indian (23%), and
African (46%). 2. CW 99113 is adapted
to and intended for use in the Southwest area of the U.S., Mexico, and
Argentina. 3. CW 99113 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 99113 has high
resistance to anthracnose (race 1), Fusarium wilt, blue alfalfa aphid,
and stem nematode, with resistance to Phytophthora root rot and spotted
alfalfa aphid. Reaction to bacterial wilt, Verticillium wilt.
Aphanomyces root rot (race 1), pea aphid, and root knot nematode has not
been adequately tested. 5. Seed increase of CW
99113 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
open isolation near Tranquility, California in 1999. Sufficient
foundation seed for the projected life of the variety will be maintained
by Ca1/West Seeds. Stands of foundation and certified seed fields are
limited to 3 and 6 years, respectively. 6. Certified seed of CW
99113 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. Variety Name: _____________________
