Panama disease, caused by Fusarium oxysporum f. sp. cubense (Foc), is ranked among the most destructive diseases of banana. The use of resistant varieties is the most desirable and effective control measure. Information on the pathogen population structure is essential, as durability of the resistance and effective cultivar deployment are strongly linked to this structure. In this study, 214 Foc isolates from different banana producing states in three regions of Brazil (north- eastern, southeastern and southern) were analysed. Initially, nine microsatellite markers (SSR) were tested, which revealed 52 distinct haplotypes distributed in the different geographical regions and cultivars. While AMOVA analysis showed that 68 01% of the total variation occurred within states, correlation between genetic and geographical dis- tances was only found in the southern region. Results indicated that isolates from different states comprise a single population, which is predominantly clonal. When isolates representing different haplotypes were inoculated in four banana cultivars, differences in severity were found, with the high severity values being caused by isolates from haplo- types H7, H31 and H41. The diversity found here points to the need for additional studies, as this characteristic may be related to Foc?s evolutionary potential and possibly to its ability to overcome the resistance from breeding pro- gramme-generated cultivars. This is the most comprehensive study on population biology of Foc in Brazil.
