The estimation of genetic parameters allows for the selection of superior individuals for important traits in plant breeding. The objectives of the present study were to estimate and predict the gains in genetic parameters, as well as to select superior individuals for morphoagronomic and pulp quality characteristics in C. moschata. Ten progenies derived from accessions collected in the northeast of Brazil were evaluated for 17 morphoagronomic characteristics and chemical quality of the pulp, including total carotenoids and β-carotene. The low values of additive genetic variance denote the need for additional selection cycles for the evaluated characteristics. Heritability greater than 30% was observed for 13 of the 17 variables analysed, indicating success in selection. Likewise, accuracy values between 74 and 93% were obtained for 15 of the evaluated variables, demonstrating the existence of high genetic variance. Individual ranking was conducted for the variables fruit weight (FRW), soluble solid content (SSC), titratable acidity (TA), total carotenoid content (CBT) and β-carotene (β-Car), identifying five individuals of progeny 10 that were promising for advancement in selection for SSC, CBT and β-car. In ranking the simultaneous evaluations for all the characteristics and taking into account the formats piriform and 'moranga', two individuals of progeny 10, which coincided with the top ranking for SSC, CBT and β-car, were identified. This identification of more than one promising individual enhances the potential of the progenies evaluated for the development of commercial and productive lines in semi-arid conditions.
