Genetic distances between pairs of accessions were obtained based on Jaccard's similarity index for RAPD data and on the arithmetic complement of the weighted index for microsatellite data. The groups were formed according to the Tocher's cluster analysis and to the unweighted pair-group method with arithmetic mean (UPGMA). The microsatellite markers were more efficient than the RAPD ones in the identification of genetic relationships. Information on the genetic distance, based on molecular characteristics and coupled with the cultivar agronomic performance, allowed for the recommendation of parents for crossings, in order to obtain superior hybrids in segregating populations for the table grape breeding program of Embrapa Semiárido.  acluster analysis  aGenetic variation  aMultivariate analysis  aMarcador molecular  aUva  aVitis Vinifera  aAnálise de agrupamento  aAnálise multivariada  aDivergência genética  aGenetic divergence  aGrapevine1 aMOTOIKE, S.
