Resumo: Forty-eight polymorphic RAPD primers were used to study the genetic similarity of eight grapevine (Vitti spp.) accessions: Itália, Seyve Villard 12327, Seyve Villard 12375, Crimson Seedless, CG 87746, A 1976, Gota de Ouro and CNPUV 154-27. Gota de Ouro, the only Vitis labrusca cultivar, was the most distant cultivar from the others. The population CNPUV 154 (Seyve Villard 12327 x CG 87746) was evaluated for fresh and dry seed weight. Four phenotypic classes were considered for dry matter percentage (DM%): 1 (DM >= 5,5), 2 (45 <= DM < 55), 3 (35 <= DM < 45) and 4 (DM < 35). The observed frequencies for the classes 1, 2, 3, and 4 were 37, 27, 53, and 9 individuals, respectively. Of the 500 RAPD screened primers, 111 were selected as polymorphic. According to BSA, markers generated by OPK02, OPS03, and OPU13 primers could be related to the region that controls seedlessness.
