This study aimed to establish super-traits for simultaneous selection of variables related to fruit yield and quality in full-sibs and/or half-sib families of yellow passion fruit (Passiflora edulis f. flavicarpa). The Design I of Comstock and Robinson was used, in random blocks with three replications, to evaluate 113 families and 11 variables. Three super-traits were determined by factor analysis: fruit size (TF), productivity (PROD) and industry yield (RI). Signals of factorial charge reflected the true sense of selection in passion fruit breeding programs for most original variables. Genetic variability was detected at the hierarchical levels of male parent and female parent within the male parent for the super-traits TF, PROD and for the respective original variables that represented it. There was no variability in super-trait RI since it was absent in the variables that represented it. Genetic gains were obtained in the desired sense in the determinant variables of the super-traits fruit size and productivity. Consequently, these can be employed in the simultaneous selection of traits related to fruit size and productivity.
