Abstract

In order to start some clonal selection works, the Aligoté and Fetească regală vine varieties from the Research and Development Station for Viticulture Iași have been subjected for several consecutive years, to works to evaluate the variability of the main quantitative characters, namely : number of shoots per stem, number of fertile shoots per stem, percentage of fertile shoots per stem, number of grapes per stem and shoot, weight of grapes per stem and shoot, number of berries per grape, weight of berries per stem and grape, as well as the mass of 100 berries. The present study aimed to determine the existing links between different quantitative characters, by calculating the regression and correlation coefficients.
