A method of clonal grape selection that allows the identification of genotypes with high productivity, based on phenotypes, with a substantial decrease in the duration of the process of selection is proposed.
Multi-stage selection of the best plants is carried out in the same stock nursery during 4-5 years. 5-6% of the selected plants include mutated and modified variations characterized not only by high productivity, normal vigor, good quality of fruit and good sanitary condition of vines, but also by a stable expression of these desirable characters.
