Conteúdo: | Fusarium wilt, caused by the fungus Fusarium oxysporum f. sp. cubense (foc), is one of the most significant constraints of banana production worldwide. The disease occurs in allbana-growing regions of the world. Considered a highly complex pathogen, studies on Foc characterisation have been performed by distinct methods, including vegetative compatibility group (VCGs). In this study, 44 isolates of Foc from some banana-growing areas of Brazil were characterised using the VCG technique. Nit mutants of Foc were pared cultured with the following VCG standards: 0120, 0121, 0122, 0123, 0124, 0125, 0128, 0129, 01210, 01211, 01212, 01213, 01214 and 01215. Results showed that the Brazilian isolates of Foc evaluated in this work belonged to VCG 0124, VCG 0125, VCG 0120, VCG 01215, VCG 0128, VCG 0123, VCG01210 and VCG01215. Isolates Foc BA 8, Foc BA 12 , Foc BA 28 and Foc BA 29 did not generate any heterokaryons when paired with the Foc standards. This is the firstreport of VCGs 0123,0129 and 1210 in Brazil.
