Pastor Corrales et al. (1998), Busogoro et al. (1999), Stenglein and Balatti (2006) identified variability between isolates of P. griseola not only at DNA level but also in the interaction with bean cultivars. Genetic diversity of the pathogen, P. griseola is crucial to develop a breeding program aimed at obtaining common bean cultivars tolerant to angular leaf spot. In this study, we continued our analysis of diversity both on a larger collection and also on several isolates from a confined area, to understand how diversity arises within representative of this pathogen.
