Technical Abstract: The best putative sources of resistance to Sclerotinia sclerotiorum (white mold) in 11 bean lines and a control were tested in seven locations. The evaluations included laboratory, greenhouse and field tests conducted in Brazil, Michigan, Nebraska, North Dakota, Oregon, Washington, and Wisconsin. Field tests consisted of two rows of each entry and a common susceptible line or variety resulting in a three-row plot 15 feet long replicated three times in a randomized complete block design. The laboratory and greenhouse tests were detached leaf, straw test, oxalate, and modified limited term inoculation. Because of the differences in data sets, e.g., field disease severity, lesion size, length of stem or number of nodes affected, the entries were ranked from most resistant (1) to most susceptible (12) in each test. A small pink line from USDA-ARS Prosser (I9365-25) was the most resistant line across locations and tests.
