If we are to breed common bean (Phaseolus vulgaris L.) for durable resistance to diseases, we must understand pathogenic variation and find sources of resistance. Our first objective was to determine the patterns of pathogenic variation found among isolates of Phaeoisariopsis griseola (PG), the f...
Twenty-four Xanthomonas campestris pv. phaseoli and X. phaseoli var. fuscans isolates, obtained from different countries and isolated from different host plants (Phaseolus vulgaris and P. lunatus, among others), were compared with nonpathogenic isolates of Xanthomonas using the restriction fragme...
