Through breeding and genetic investigations in F1 progeny of hybrid combinations between sedded and seedless grapevine cultivars, it was established that berry size, shape and weight are polymeric traits, inherited through incomplete dominance of cultivars with smaller and round berries. The phenotypic manifestation of seed weight and number in seeded forms confirmed that berry seedlessness is determined by dominant genes, too. To develop new high-yieldin elongated seedless grapevine cultivars it is necessary to cross large-fruited parent cultivars with oblong berries, and selection should be done on a large number of plants.
