Twenty five isolates of Colletotrichum gloeosporioides obtained from fruits of olive, apple and citrus trees from different regions of Golestan province, northern Iran. Results from cross-inoculation experiments showed a great variability in pathogenicity among the isolates examined. They were investigated using complementation tests with nitrate-non-utilizing (Nit) mutants to know their vegetative compatibility. Among 250 chlorate-resistant sectors obtained, only 187 were Nit mutants. Three types of Nit mutants were obtained (Nit1, Nit3 and NitM) on the basis of the fungal phenotype.
