The purpose of this study was to evaluate the reaction of 104 genotypes of commom bean, obtained from the Germoplasm Active Bank located at "Instituto Agronômico de Campinas" to four physiologic races of Fusarium oxysporum f.sp. phaseoli under greenhouse conditions. Disease severity was evaluated 30 days after inoculation using a scale ranging from 0 ( no symptoms of wilting) to 4 ( plants totally wilted and or dead). Plants receiving disease severity values until 2 were considered resistant and above 2 were susceptible. A total of 35 genotypes (33%) showed resistance to the four races of the pathogen. The variability found among the genotypes of commom bean genotypes in response to the four races of pathogen indicates a potential use of this germoplasm in breeding programs for disease resistance.
