This work aimed to perform the morphological and molecular characterization of 31 land races varieties and 9 cultivars of common bean (Phaseolus vulgaris L.). Morphological characters were evaluated during seedling, flowering, physiological maturation and post-harvest maturation stages. Ten microsatellite markers were used for molecular screening. The markers were analyzed according to the number of alleles per locus, the allele frequency per locus and the polymorphism in content (PIC). Genetic distances and cluster analysis were performed using the Bayesian inference and the UPGMA method. All black beans evaluated have anthocyanin in the cotyledons, hypocotyls and stem, and their flowers are purple. For the growth habit, 50% of the evaluated genotypes belong to the type III and there is a predominance of yellow color in the pods (85%) at the physiological maturation stage. Through the genetic dissimilarity it was possible to discriminate three groups for the Likelihood reason and six groups through the UPGMA method, these results indicate a wide genetic diversity among the evaluated genotypes.
