Resumo

The present work had objective to evaluate the genetic divergence among 63 traditional cultivars of the common bean (Phaseolus vulgaris L.) collected in Paraná state in the period 2001-2002. The experiment was carried out in an experimental area in 2002 in the county Toledo, PR. The experimental design was a randomized block with three replications. The Multivariate was used to evaluate the divergence among the genotypes, utilizing the Canonic Variable analysis and clustering, based on the Generalized Mahalanobis Distance ( 2 ii' D ) for the quantitative variables. The results demonstrated that the most divergent cultivars were Carioca Pitoco and Jalo vermelho, whereas the most similar were Carioca Pitoco and Carioca. These results point out the existence of genetic variability in common bean cultivars used by farmers, and multivariate analysis methods demonstrated efficiency to detect them, separating the cultivars Carioca and Jalo in different groups. Therefore, in order to compose the interpopulation selection programs the Carnaval (33), Carioca Pitoco (16), Pérola (14) and Carnaval (27) cultivars are recommend because they are the most divergent ones and possess one of the best averages in productivity.
