Resumo: | The aim of this work was to study the genetic parameters, to obtaine the progenies by crossings among the yellow passion fruits cultivars (Passiflora edulis f. flavicarpa), following the Design I. The results of the variance analysis demonstrated large variability to be exploited in the population. The trait number of fruit per plant presented the largest additive genetic variation coefficient, demonstrating that larger gains could be obtained for the trait. In terms of genetic action, number of fruits per plant, skin thickness and number of days by flowering have demonstrated to be characterized by the overdominance. Other important traits seem to have presented larger addictive effect than the dominance, as weight, length and width of fruits. The highest values of the coefficients of heritabilities were obtained for the males and the smallest for the females within males, and for the selection the coefficients should be used in the narrow sense.
