This paper presents the agrobiological and technological results obtained during the first stages of the clonal selection applied to the Augusta and Victoria varieties. 10 clonal selections of both varieties of table grapes were studied. The determinations and analyzes consisted in the evaluation of agrobiological descriptors:, calculation of absolute and relative fertility coefficients. Physico-mechanical analyzes were carried out, consisting in the evaluation of the number of berries, the weight of the pulp, the weight of the skin, of the seeds in one kilogram of grapes. The clonal selections Augusta 2 and 8 stood out for their fertility of 65% and 59%, respectively, but also for their high values of the absolute and relative fertility coefficients Afc - 1,3, Rfc - 0,83 respectively Afc - 1,3, Rfc - 0,27. Regarding the clonal selections Victoria 4 and 10 stood out for their fertility of 76% and 77%.
