                                    Citation: Riday, H., Albrecht, K.A. 2010. Registration of Kura1 a Trifolium ambiguum (M. Bieb)germplasm. Journal of Plant Registrations. 4:80-85.Interpretive Summary: Little improved kura clover exists in the US.  Improving kura clover through plant breeding is a means to rectify this situation.  This study gives the breeding background and field test data for a new kura clover germplasm 'Kura1' developed in Wisconsin that has good yield and is available for further development and breeding.  Breeders and seed producers can utilize this new germplasm and field testing information to produce varities and seed for farmers.
                                Technical Abstract: Kura1 is a broad-based autohexaploid (2n=6x=48) Trifolium ambiguum (M. Bieb) germplasm selected for aggressive rhizomatous spreading ability and plant vigor in a Southern Wisconsin environment.  Kura1 was developed jointly by the University of Wisconsin-Madison and the U.S. Dairy Forage Research Center (USDA-ARS), Madison, WI and released jointly by the USDA-ARS and the University of Wisconsin Agricultural Experiment Station in December 2006.  Few improved kura clover breeding populations exist in North America with even fewer named varieties.  Kura1 germplasm is a very competitive addition to the improved germplasm base available to breeders.  Kura1 was developed by selecting 69 parents for persistence, vigor, and spreading ability out of a common space plant nursery of 35 kura clover plant introductions, breeding populations, germplasms, or varieties.  Syn1 seed was produced in Wisconsin in 2004 and Syn2 seed was produced in Wisconsin in 2008.  Kura1 has superior yield to ‘Cossack’ and ‘Rhizo’ in Southern Wisconsin.  Kura1 also has extensive additive variance for important traits of seedling establishment and vigor, general plant vigor, rhizomatous spreading ability, and seed yield.
