The article is dedicated to study of factors influencing the production structure of the grapevine, its formation and development. During the researches made for evaluating the genetical potential of the productivity of different grape varieties, its genotypical, phenotypical, agroecological, agronomic and etc. parameters were studied. Although the grape productivity depends on its genetical nature, it bears the polygenic character and the process is characterized by variability. During the morphological study of the traits, analysis of mathematical-statistical relations, including correlational and regressional relations, it was found that the productivity of the plant, size and weight of the berries and clusters, quantity and average weight of the clusters, the weight of 100 berries, the number of the berries in the cluster, the bud load of the plant, the amount of productive shoots have directly proportional correlation and play a key role in the formation of productivity.
