OLIVEIRA, JAMILE DA SILVA; FALEIRO, FÁBIO GELAPE; JUNQUEIRA, NILTON TADEU VILELA  e  VIANA, MARCELO LIBINDO. GENETIC AND MORPHOAGRONOMIC DIVERSITY OF Passiflora spp. BASED ON QUANTITATIVE MEASUREMENTS OF FLOWERS AND FRUITS. Rev. Bras. Frutic. [online]. 2017, vol.39, n.1, e-003.  Epub 13-Abr-2017. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452017003.

The aim of this study was to characterize Passiflora spp. accessions and its genetic diversity based on quantitative morphological descriptors of flowers and fruits. The study was conducted at Embrapa Cerrados, Planaltina-DF. Fifteen Passiflora spp. accessions were characterized using 14 quantitative morphological descriptors. Genetic distances among accessions were estimated based on Mahalanobis’ generalized distance. Cluster analysis via dendrogram and graphic dispersion was analyzed. The relative contribution of characters for accession divergence was also calculated. The morphoagronomic characterization based on quantitative descriptors of flowers and fruits contributed to the differentiation of Passiflora spp. accessions, serving as an important tool for variability quantification. This information is useful to perform Passiflora spp. characterization and genetic diversity studies.
