ABSTRACT

Sclerotinia rot caused by Sclerotinia sclerotiorum is a serious threat to green beans production in Egypt. The pathogenicity of this pathogen to 11 different cultivars was measured by survival plants % in the genotypes. Significant differences were observed between different cultivars (P?0.005). Results indicate that, Amy and Giza cultivars were more susceptible to infection with S. sclerotiorum that produced 16% survival plants in both cultivars after 60 days. While, Duel cultivar was less sensitive to infection with the pathogen that giving 40% living plants at 60 days.
