Three bunch traits (bunch length, bunch width and bunch weight) were investigated in four interspecies crossing combinations of grapevine (Seedling 108 x Muscat Hamburg, Muscat Hamburg x Seedling 108, S.V.18315 x Muscat Hamburg and Muscat Hamburg x S.V.12375) during three years period. Based on results of analyses of variance for all investigated traits, components of variability, coefficients of genetic and phenotypic variation and coefficient of broad-sense heritability were calculated. It was established that in all investigated traits and for all crossing combinations, genetic variability took the biggest part in total variability. Considering examined crossing combinations, the coefficient of heritability for bunch length, i.e. bunch width and bunch weight ranged from 69.14% to 87.04%, i.e. 64.27% to 80.02% and 66.53% to 80.36%, respectively.
