The knowledge of the post-harvest characteristics of new banana genotypes is important an information that helps the breeder in making a decision. This work had the objective of evaluating the fruit physical and chemical characteristics of genotypes of three banana genomic groups: 'Nanicão-IAC-2001', 'Grande Naine', 'Caipira', and 'Nam' (AAA); 'Maçã', 'Thap Maeo', 'Prata Anã', and 'Prata Zulu' (AAB); 'Fhia 01', 'Fhia 18', 'Prata Graúda', and 'Tropical' (AAAB) in Botucatu region, São Paulo state, Brazil. The evaluated characteristics were: firmness, pH, titratable acidity, soluble solids, total soluble sugars, starch, and potassium contents. The experimental design was completely randomized, with 12 treatments (genotypes), five replications and each replication consisting of five fruits. The method used was the Tukey test (Pd" 0.05) for the characterization of genotypes within each genomic group. The results showed that in the AAA group, Nam stood out due to the firmest fruits and the highest levels of soluble solids and starch. In the AAB group, 'Prata Zulu' presented the firmest fruits, the highest levels of total soluble sugars and starch, and the lowest acidity. In the AAAB group of hybrids, 'Tropical' had highest content of potassium and starch, however, lowest content of soluble solids and total soluble sugars.
