Interpretive Summary: The USDA-ARS Dry Edible Bean Project at Prosser, WA, released five new dry bean germplasm lines, four navy and one black, with improved resistance to common bacterial blight. Common bacterial blight is a seed borne vegetative disease that plagues bean production worldwide. It is a major disease in the midwestern United States (Michigan, North Dakota, Nebraska, and eastern nColorado), and is the primary reason why most bean seed production occurs in the west (California, western Colorado, Idaho, Oregon, and Washington). In addition to common bacterial blight resistance, the lines possess genes conditioning resistance to bean common mosaic virus and rust. These lines will be useful for improving resistance to common bacterial blight in navy and black dry edible bean market classes.

Technical Abstract: The USDA-ARS and the Agricultural Research Centers of Washington State University, North Dakota State University, and Michigan State University announce the release of four navy and one black dry edible common bean (Phaseolus vulgaris L.) germplasm lines USNA-CBB-1, USNA-CBB-2, USNA-CBB-3, USNA-CBB-4, and USBK-CBB-5 with moderate levels of resistance to common bacterial blight (CBB). Common blight is a seed borne vegetative disease that plagues bean production worldwide. It is a major disease in the midwest United States (Michigan, North Dakota, Nebraska, and eastern Colorado), and is the primary reason why most bean seed production occurs in the west (California, Colorado, Idaho, Oregon, and Washington). In addition to common bacterial blight resistance the lines possess resistance to rust (Uromyces appendiculatus) races prevalent in U.S. bean production areas and the I gene for resistance to bean common mosaic virus (BCMV). These germplasm lines will be useful for improving common bacterial blight resistance in navy and black dry edible bean market classes.
