Interpretive Summary: Common bacterial blight is a major disease problem affecting white kidney bean production in the U.S. The best control measures involve planting disease-free seed and deploying genetic resistance. Chemical control is ineffective. Unfortunately white kidney beans do not possess genetic resistance for combating this devastating pathogen. We here at Prosser along with collaborators from the University of Idaho, developed a white kidney bean germplasm line USWK-CBB-17 with a high level of resistance to common bacterial blight. This line will be useful for developing white kidney beans with resistance to common bacterial blight, leading to enhanced yield and improved economic return for white kidney bean producers in the U.S.

Technical Abstract: White kidney bean germplasm line USWK-CBB-17 was developed by USDA-ARS in cooperation with the Idaho Agricultural Experiment Station and released in 2006. This line was bred with a high level of resistance to common bacterial blight caused by Xanthomonas axonopodis pv. phaseoli (Xap). Common bacterial blight is a major seed-borne disease endemic to the U.S. bean production regions east of the continental divide and problematic in Colorado, Michigan, Minnesota, Nebraska, New York, North Dakota, and Wisconsin. USDK-CBB-17 possesses two major QTL that confer a high level of resistance to Xap. Marker-assisted selection using the SAP6 sequenced characterized amplified region (SCAR) marker tightly linked with a QTL derived from great northern landrace cultivar Montana No.5 and SU91 SCAR marker with a QTL from breeding line XAN 159 (Pedraza et al., 1997) facilitated the development of USWK-CBB-17.
