Resumo: This study aimed to perform phenotypic characterization and to analyze the genetic diversity of Passiflora spp. accessions using qualitative multicategoric descriptors from leaves and flowers. The study was conducted in the Active Germplasm Bank 'Flor da Paixão' at Embrapa Cerrados. One hundred and twenty five Passiflora spp accessions were characterized using 48 qualitative multicategoric descriptors (23 from sheet and 25 from flower). Frequency distribution of accesses on different phenotypic classes of each descriptor was used to estimate the entropy coefficient for each descriptor. Genetic distances between accessions were estimated using a simple coincidence index. From the genetic distance matrix, grouping analysis via dendrogram were performed using as criterion the Unweighted Pair-Group Method using Arithmetic method Avarages. Phenotypic characterization based on qualitative multicategoric descriptors contributed to the 125 Passiflora spp. accessions differentiation. These characterization serving as an important tool to quantify the existing diversity and accessions differentiation.  It is important for more comprehensive studies of genetic diversity and characterization of Passiflora genetic resources.

Sendo assim, objetivou-se realizar a caracterização fenotípica e analisar a diversidade genética de acessos de Passiflora spp., baseada em descritores multicategóricos de folhas e flores. O estudo foi realizado no Banco Ativo de Germoplasma ‘Flor da Paixão’ da Embrapa Cerrados. Foram caracterizados 125 acessos de Passiflora spp. utilizando 48 descritores qualitativos multicategóricos (23 de folha e 25 de flor). Com base na distribuição de frequência dos acessos nas diferentes classes fenotípicas de cada descritor, foi estimado o coeficiente de entropia de cada descritor. Foram estimadas distâncias genéticas entre os acessos, por meio do complemento do índice de coincidência simples. A partir da matriz de distâncias genéticas, realizou-se a análise de agrupamento via dendrograma, utilizando como critério o método Unweighted Pair-Group Method using Arithmetic Avarages. A caracterização fenotípica baseada em descritores multicategóricos contribuiu para a diferenciação dos 125 acessos Passiflora spp., servindo como importante instrumento para quantificar a diversidade existente e clara separação entre as espécies, sendo importante para estudos mais completos de caracterização e diversidade de recursos genéticos do gênero Passiflora.Universidade Federal Rural da Amazônia/UFRA2018-02-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2427Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 60 No 3 (2017): RCA; 223-234Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 60 n. 3 (2017): RCA; 223-2342177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
