Inheritance of Some Grapevine Properties in Progeny from Direct and Reciprocal Crossing of Cultivars 'Smederevka' and 'Red Traminer'

Abstract

Variability and inheritance of important agronomic, biological, and technological characteristics of grapevine in two hybrid progeny obtained by direct and reciprocal crosses of cultivars 'Smederevka' and 'Red Traminer', were investigated in this study. F-1 seedlings from both cross combinations showed high level of variability for all examined properties. Coefficient of variation in both direct and reciprocal crosses showed the lowest value for sugar content in the must (5.9% and 6.4%, respectively) and the highest value for grape yield per hectare (63.2% and 63.7%, respectively). In both cross combination, for majority of characteristics, the same mode of inheritance was established, except for ripening time. From all examined characteristics, important influence of cytoplasm factors was determined only for inheritance of flowering time and ripening time.
