The application of Path-analysis for the investigation of yield structure and variability of quantitative traits in a cross between a seeded and a seedless vine cultivar is presented. Yield from parent cultivars and F1 progeny of the hybrid combination 'Armira' x 'Russalka 1', is most significantly influenced by the traits related to actual vine productivity, the ampelometric indices of cluster and berry, and shoot fertility coefficients. The parent cultivars 'Armira' and 'Russalka 1' specifically influence the phenotype of hybrid plants through various traits from almost all conditionally formed groups. Determination of the most important traits for the productivity of different vine cultivars as well as the relative participation of these traits in their total variation in F1 progeny, increases the efficiency of vine selection.
