This study shows the results obtained using the AFLPs of <em>M. roreri</em>. The kit for analysis system II was standardized and applied to 56 samples of <em>M. roreri</em>, isolated from nine municipalities. The combination with the highest number of polymorphisms was E-ACC/M-CAA. With 90 bands and a smaller number of alleles (6), the E-ACG/M-CAA combination yielded 90 bands and a larger number of alleles (23); the E-AAC/M-CAA combination had 94 bands and alleles (12). The data analysis was carried out according to the dendrogram of similarity or genetic distances of Nei, obtaining five groups with a high variability between samples, from 6.5 to 58%. By combining the morphological and molecular information, the level of genetic diversity in <em>Moniliophthora roreri</em> was determined. ER -
