The present study had as objective to evaluate of the genetic divergence among 35 landraces of common bean. The experimental design was carried out in a randomized block with four repetitions. The variance analysis revealed significant difference at 1 and 5% levels of probability for the evaluated characteristics. The Cluster analysis based in the morpho-agronomic traits presented difference among Andean and Mesoamerican landrace cultivars, which it allocated the landrace cultivars in different groups. The Tocher and the Nearest Neighbor methods demonstrated that the most dissimilars cultivars were Carioca sem Cipó and Jalo, whereas Roxinho Mineiro and Carioca sem Cipó cultivars were the more similars. The first two canonic variables were sufficient to explain about 81.90% of the total variation showed in this study. These results reveal large genetic diversity among the landraces from Mato Grosso do Sul state.
