The aim of the study was to determine genetic correlations of agronomic traits and to evaluate direct and indirect effects, through path analysis, between variables analyzed with grain yield. Forty accessions of common bean, cultivated at Caceres County were evaluated, by using randomized complete blocks design with three repetitions. Coefficient magnitudes of genotypic correlations were superior to phenotypic and environmental ones for most correlations, suggesting greater influence of genetic factor than environmental factors. In order to determine the importance of direct and indirect effects, path analysis was performed, which provided greater reliability in interpretations of cause and effect between studied traits, indicating that grain yield may be explained by the effects of analyzed traits. Number of seeds per plant (0.801) and grain weight (0.641) showed higher favorable effect over grain yield, allowing its use in direct or indirect selection for grain yield in common bean.

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.
