Resumo: The adoption of a new banana variety resistant to black-Sigatoka depends on its agronomical and physical-chemical characteristics. The potencial of a new cultivar can only be known upon evaluation. The objective of this study was to characterize seven banana varieties that were resistant to the diseaseby comparing them to a variety which is traditionally used by industries. The following variables were evaluated: pH, TIA, TSSITTA, total sugars, reducing sugars and non-recuclnqsuqars, humidity, total solids and yield. The data were evaluated by single and multivariate analyses. Thap variety showed a better performance çompared tolhe Grande Nainevariety, surpassing it,ln the leveis oftotal soluble soJids,reducing sugars, total $ugars and humidity.

The greatest diversity among these varieties occurred in regard to sugar composition and the total solids. The (3rande Naine variety was found to be close to the varieties of the Gross Michel subgroup (Bucaneiro, , Ambrosia and Calipso) and the Caipira variety in the cluster analysis, since they ali come from the same AAAgenomic group.
