Genetic diversity of Passiflora spp., based on morphoagronomic descriptors
The objective of this study was to assess the morphoagronomic characterization of Passiflora spp. accessions, using multicategoric descriptors based on leaves, flowers and fruits. Fifteen Passiflora spp. accessions were characterized using 58 multicategoric qualitative morphological descriptors (23 from leaves, 25 from flowers and 10 from fruit). Genetic dissimilarities among all accession pairs were estimated based on the simple coincidence index complement. These genetic dissimilarities were used to perform the cluster and a dendrogram was obtained based on UPGMA method (Unweighted Pair-Group Method using Arithmetic method Averages). The dispersion graphic was based on multidimensional scaling using the principal coordinates (PCO). There was a clear differentiation of all accessions at interspecific and intraspecific level, based on multivariate analysis of leaves, flowers and fruits descriptors. There was a tendency of grouping Passiflora alata accessions. The morphoagronomic characterization contributed to differentiate the 15 Passiflora spp. accessions. The information are useful as an important tool to quantify the Passiflora morphological variability.
