Conteúdo: | The intra- and inter-specific genetic dissimilarity between 14 ‘yellow’ passion fruit plants and eight ‘sleep’ passion fruit plants were evaluated through nine physical-chemical descriptors, whose measured values were submitted to descriptive (average, standard deviation and variation coefficient) and inferential [univariated (ANOVA, averages and correlations tests) and multivariated (Mahalanobis distance, hierarchical clustering, Singh coefficient and Mantel test)] statistics. Intra- and, especially, inter-specific variability were found among the passion fruit plants (p < 0.001). The total soluble solid, equatorial diameter, total titratable acidity, and fruit weight descriptors presented the highest percentage of relative contribution, totaling 85.2% of the observed divergence. Preferential crossings among genotypes with physical-chemical characteristics of desirable fruits and useful genetic dissimilarity in divergent and convergent crossings were identified.
