9429 1. 9429 is a synthetic variety with 273 parent plants which were selected sequentially for multifoliolate leaf expression and for resistance to Phytophthora root rot and Aphanomyces root rot (race 1). Parent plants were selected from crosses between selections from three year old Wisconsin and Minnesota yield tests and various populations which 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, Verticillium wilt, Phytophthora root rot, Aphanomyces root rot (race 1), anthracnose (race 1), and Leptosphaerulina leafspot. Parentage of 9429 traces to the following germplasm sources: BigHorn, AlfaStar, Award, MultiQueen, and miscellaneous Cal/West Seeds breeding populations. Approximate germplasm, source contributions are as follows: M. falcata (8%), Ladak (6%), M. varia (25%), Turkistan (4%), Flemish (47%), and Chilean (10%). 2. 9429 is adapted to the north central and east central areas of the U.S. and is intended for use in the north central and east central areas of the U.S. 9429 has been tested in Wisconsin, Minnesota, Michigan, and Nebraska. 3. 9429 is a moderately dormant variety with fall dormancy similar to Saranac. Flower color observed in the syn2 generation is greater than 93% purple and 7% variegated, with a trace of cream, white, and yellow. 4. 9429 has high resistance to anthracnose (race 1), bacterial wilt, Fusarium wilt, Phytophthora root rot, Aphanomyces; root rot (race 1), and blue alfalfa aphid, with resistance to Verticillium, wilt, stem nematode, pea aphid, and spotted alfalfa aphid. Reaction to root knot nematode has not been adequately tested. 5. Seed increase of 9429 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 3), and certified (syn3 or 4) classes will be recognized. Production of syn3 foundation seed requires consent of the breeder. Breeder seed was produced under cage isolation near Woodland, California, in 1995. 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 three and six years, respectively. 6. Certified seed of 9429 will be available in 1998. 7. No decision has been made regarding Plant Variety Protection. 8. This information can be forwarded to the PVP office. 9. Variety name: 9429 Experimental designation: CW 5426 Date first accepted this variety: January 1998 Date previous amendments were accepted: January 1999 Date this amendment submitted: November 30, 1999
