The present research was conducted at the experimental unit of the Empresa Mato-Grossense de Pesquisa, Assistência e Extensão Rural-EMPAER (Caceres-MT) and aimed to determine the genetic variability that exist among 40 accesses from active germplasm bank of Phaseolus vulgaris L. of the region Caceres-MT. It was used a random blocks design with three replications and analyzed eleven agronomic characteristics. Data were submitted to analysis of variance, it was estimated the genetic variability among the accessions through multivariate analysis based on Mahalanobis distance, performing cluster analysis. There were significant differences at 1% probability for all the characteristics evaluated. The largest genetic distance was found between accessions 13 and 20 (D2 ii'=364.99), and the smallest distance between accessions 13 and 26 (D2 ii'=2.23). Methods of Tocher and UPGMA ordered the most divergent accessions into distinct groups, showing the existence of variability and can be included in breeding programs with a regional focus.
