The ability to identify genetic variation is indispensable to effective management and use of genetic resources. This work is the first approach concerning to generation and genetic differentiation of new Musa hybrid lines obtained in INIVIT (Cuba), crossing Musa acuminata male diploid (AA) x female triploid (ABB), genotypes selected by their resistant character to pests and diseases. From the obtained hybrids, only five were chosen because of their agronomic behavior and were genetically discriminated among them and also respect to the commercial clone FHIA-18 by AFLP polymorphism. Thanks to this prior genetic characterization Musa breeding programs could be consistently dinamised
