Interpretive Summary:

Technical Abstract: The Agricultural Research Service, U.S. Department of Agriculture, and the Idaho Agricultural Experiment Station announce the release of USWK-CBB-17 white kidney (Phaseolus vulgaris L.) germplasm line 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 of dry and snap beans worldwide. The disease is 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. Genetic resistance in the host provides the most effective control of this disease, and planting certified disease-free seed is critical. USDK-CBB-17 possesses two major QTL and perhaps other minor genes that confer a high level of resistance to Xap. Marker-assisted selection using the SAP6 and SU91 markers tightly linked with QTL derived from great northern landrace cultivar Montana No.5 and breeding line XAN 159, respectively, enabled us to expedite development of USWK-CBB-17 for combating this entrenched disease problem in the U.S.
