Despite efforts in the selection and the identification of mango cultivars resistant to Ceratocystis wilt, the genetic basis of the resistance remains unknown. Therefore, the objective of this study was to understand the inheritance of resistance to C. fimbriata by artificial inoculations of the pathogen in progenies of six commercial varieties of mango using ?Tommy Atkins? as the male parent. The cultivars ?Keitt?, ?Palmer?, ?Tommy Atkins? and ?Van Dyke? were confirmed as moderately resistant, whereas ?Coquinho?, ?Espada? and ?Haden? were susceptible. The results of the inoculation on the progenies of these cultivars revealed that the resistance in mango is polygenic with a prevalence of genes expressing the effects of dominance and epistasis. The genetic gain with the selection of the 10 more resistant plants was 46%, which indicated a 46% reduction in disease severity. In general, a low frequency of the alleles favorable to disease resistance was observed in the population studied, which suggests the need for the introduction of new sources of genetic materials carrying the genes responsible for resistance.  aPlant diseases and disorders  aDoença de planta  aFungo  aManga  aMangifera Indica  aCeratocystis wilt  aEspécie exótica1 aGUIMARÃES, L.
