These research objectives were to estimate the simple correlations (phenotypic, genotypic and environmental) and canonic correlations; in order to do that, it was evaluated five characteristic related to the fructification and three characteristics related to the quality of the fruit in two yellow passion populations grown in two environment (Macae and Campos dos Goytacazes). To the Macae environment in 32% of the simple associations, the genotypic correlations were the higher than the environmental correlations, indicating that the environment component is more influent than the genotypic component. To the Campos dos Goytacazes environment, in 50% of the simple associations, the genotypic correlations were higher than the environmental correlations, verifying, as it was observed in Macae environment, that the environment component is more influent than the genotypic component; it was observed high genotypic correlation between weight and fruit length. To the canonic correlations in the Macae environment, it was demonstrated that the individuals with high content of acidity and brix would have the tendency to present reduction in the fruit number, fruit length and peel tickness. In Campos environment reduction in the peel thickness and fruit length can increase the juice content and brix content.
