Abstract

Clonal selection in viticulture is based on genetic variability with the aim of creating superior plants (clones) that enable more economical production. The Riesling variety, with a long tradition of cultivation, has been the subject of extensive clonal selection and clones 49, 1089 and 1091 were created in France. During the two-year period (2016-2017), the productivity and oenological potential of Riesling clones 49, 1089 and 1091 in the agroclimatic conditions of Bosnia and Herzegovina were conducted. Significant differences between clones were found in the yield per vine (1.34-1.87 kg), ten skins weight (2.17-2.46 g) and mass of ten berries seeds (0.27-0.35 g). The highest soluble solids content was found in clone 49 (22% Brix). Significant variation in the content of total polyphenols in the grape skin was observed in clones 49 and 1091 during the research period, compared to clone 1089 where the differences were less pronounced. The tested clones statistically differed each other significantly in most of the tested wine characteristics, except for the content of volatile acids. Clone 49 had slightly better results in terms of yield indicators, as well as a more uniform yield compared to clones 1089 and 1091. The tested clones, grown in agroecological conditions of northwestern part of Bosnia and Herzegovina showed satisfactory results in terms of grape and wine quality, which do not lag the Riesling variety in terms of literary data.
