Conteúdo:	The pathogenic variability was evaluated of 48 Pseudocercospora griseola isolates collected in the State of Minas Gerais, Brazil. Isolates were inoculated to a set of 12 international differential cultivars in a greenhouse. Ten pathotypes (55-15, 63-7, 63-15, 63-23, 63-25, 63-27, 63-31, 63-47, 63-55 and 63-63) were identified, showing the great pathogenic variability of this fungus in Minas Gerais State. Pathotypes 55-15, 63-15, 63-25 and 63-27 had not previously been reported in the State. Of the 48 isolates, all except pathotype 55-1547 induced a compatible reaction with all cultivars from the Andean group. Isolates were highly pathogenic in both Andean and Mesoamerican cultivars, thus being classified as Mesoamerican pathotypes. Pathotype 63-63 was the most widespread, and overcame the resistance genes present in all differential cultivars.
