Interpretive Summary: The USDA-ARS Dry Edible Bean Germplasm Enhancement Project at Prosser, WA, released three kidney bean germplasm lines: USLK-2 light red kidney, USDK-4 dark red kidney, and USWK-6 white kidney, with complete genetic resistance to bean common mosaic virus and bean common mosaic necrosis virus. These seed borne viruses plague bean production worldwide, and are an extreme nuisance for seed producers in the Pacific Northwest. A single plant infected by one of these viruses in a seed production field is enough to reject the entire seed lot. These lines are immune to the virus and thus ensure virus free seed production and no yield loss from the disease saving growers time and money. These three lines will be most useful to plant breeders and seedsmen interested in incorporating extreme resistance to potyvirus in the kidney bean market class.

Technical Abstract: Three dry edible kidney bean (Phaseolus vulgaris L.) germplasm lines with complete resistance to bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) were developed by USDA ARS Prosser, WA. BCMV and BCMNV are seed-borne viruses that adversely effect production and distribution of bean seed worldwide. These lines possess the I and bc-3 gene combination that conditions an immune reaction to all strains (we tested US-1, US-7, NL-8, US-3, US-5, NY15, Russian, NL3, NL-5, US-6, and NL-4). Presence of the hyostatic I gene was confirmed by presence of the linked DNA marker SW13 (SCAR). All three lines exhibit upright determinant bush growth habits and good yield potential in both tropical and temperate environments.
