Abstract : A clone, in a viticultural context, is “a single vine or a population of vines all derived by vegetative propagation from cuttings or buds from a single “mother vine” by clonal selection. The aim of this paper was to evaluate how different clones of the autochthonous ‘Ceruja’ white grapevine variety express their productivity indicators and oenological characteristics and to recommend the best clone to be propagated and used in the vineyard variety structure in Albania. The study was conducted during three executive years (2020-2022). Nine clones (4, 13, 58, 124, 251, 367, 413, 489, and 582), grafted over 140Ru, with a plot size of 10 vines for each clone, were evaluated. Yield per plant, single bunch weight, berry weight, ten berries skin weight, ten berries seed weight, total soluble solids, total tartaric acid, pH of must and wine, alcohol fraction for volume, and total polyphenols in berry skin and seeds, were measured using specific tools, as described by the OIV, and were recorded for a 3-year period. There was found that different clones showed significant differences in terms of quantity and quality of grape and wine characteristics. Clone 413, followed by clones 58, 124 and 4, showed the highest productivity and wine quality characteristics and are recommended to be used in the varietal structure of the North and North-Eastern part of Albania as clones of perspective for white wine production, in context of rural tourism development in these areas and beyond.
