Twenty-three soybean (Glycine max) cultivars were evaluated for their resistance to Sclerotinia sclerotiorum in naturally infested field plots. The cultivars Corsoy, Hodgson, and Hodgson 78 were less susceptible to S. sclerotiorum than other cultivars. Resistance or susceptibility to S. sclerotiorum was not related to plant architecture or soybean maturity group.
