Seventeen Latin American isolates were studied for virulence characteristics on a group of 21 bean cultivars. Large differences in virulence were found among isolates for disease severit, lesion size, lesion umber, sporulation capacity, and number of days required to cause a given level of disease. No cultivar was resistant to all isolates of the pathogen; however, regression analyses indicated that several cultivars such as A 339 and BAT 1647 show presence of several components of non-specific resistance.
