P. Vulgaris species is an important source of proteins in the human diet in developing countries in tropical and sub tropical regions, especially in the Americas and West Africa. To know the genetic diversity among commercial and Creole cultivars is very useful to breeders because it allows an adequate organization of the genetic resources and a better exploitation of the available genetic diversity. The objective of this work was to identify the genetic diversity among and into Carioca type common bean accesses stored in the Active Germplasm Bank at Embrapa Arroz e Feijão. The experimental design was a completely randomized bloc with three replicates and carried out at the same institution in the municipality of Santo Antônio de Goiás with the following geographical coordinates: 16.30´S; 49.17´W at 814 m altitude. The evaluation was performed based on fifteen morphoagronomic qualitative descriptors and fifteen quantitative descriptors as well. Nine out of fifteen descriptors were uniform in all accesses. The quantitative descriptors were analyzed using canonical variate analysis; the agglomerative clustering method of Ward, and the univariate variance analysis associated with the Tukey test to evaluate the effect of clustering on the variables and to compare the means of the groups among them. Through the canonical variate analysis it was possible to discard three variables with little contribution to the total phonotypical variability among the accesses. Taking in account the twelve variables left, it was necessary to consider the first five canonical variables to explain 68% of the total variance. Even though the dispersion plot of the accesses related to the two first canonical variables (57%) evidenced phonotypical variability in the accesses studied. Variables flowering days, number of locules per pods and pod beak length were considered the most discriminatory. Accesses CF870015 and CF 830128 were identified as the most diverging between themselves. Through cluster analysis, using the fifteen quantitative descriptors, six similar groups were established. Observing the average of the phenotypic characteristics of each group and the dispersion of the accessions, it was observed concordance between the canonical variate analysis and clustering. Based on the analysis of variance of the quantitative descriptors, the variables leaf width, number of pods per plant, pod beak length and number of locules per pods indicate non significant difference, while the other variables presented highly significant differences at the 5% level.application/pdfAcesso abertorecursos genéticosPhaseolus vulgaris L.análise multivariadagenetic resourcesmultivariate analysisGENETICA::GENETICA VEGETALTese
