Technical Abstract: K-42, K-59, and K-407 breeding lines of red kidney bean (Phaseolus vulgaris L.) (PI 578272 to PI 578274) were jointly released in October 1986 by the USDA-ARS and Washington State University. These breeding lines of diverse genotypes are all resistant to curly top virus (CTV) and have the dominant I gene resistance to bean common mosaic virus (BCMV). All have strong upright, determinate, red kidney bush growth habits. They range in maturity from 85 to 100 days in Washington and Idaho. All are competitive in yielding ability and similar in seed characteristics to present commercial cultivars. Cooking quality was comparable to that of commercial cultivars (unpublished test results). K-42, one of the earliest-maturing of the group, is a light red kidney (LRK) F6 selection from the parentage 'Mecosta'/6/'Manitou'/5/'Jacob's Cattle'/4/'Tenderlong 15'/3/710-5/1831/2/ stiff bush breeding line/'California Dark Red Kidney'(DRK). K-42 showed halo blight resistance in 1985 Colorado field trials. Its pods tend to shatter when dry. K-59 is an LRK F6 selection from the parentage Mecosta/ 2/'Royal Red'/'Redkote'. Inoculation tests have shown K-59 stems, leaves, and pods resistant to Race 2 of the halo blight bacterium. K-407 is a DRK F7 selection from the parentage Royal Red/2/27R/Royal Red. It has shown no known resistance to the bacterial or fungal diseases referred to above. Small amounts of seed of these selections can be obtained from P. N. Miklas, Prosser, WA.
