Inheritance of mature leaf properties in grapevine progeny obtained by crossing Muscat Hamburg and Villard Blanc cultivars

摘要

and inheritance mode of six properties of the mature leaf (size of blade, number of lobes, shape of teeth, general shape of petiole sinus, density of prostrate and erect hairs between veins on the lower side of blade) were analyzed in 90 seedlings of the F1 generation from the crossing combination of Muscat Hamburg x Villard Blanc. The properties analyzed were classified according to the OIV system of classification and χ2 test was used to determine the inheritance mode. A substantial variability of the analyzed characteristics was recorded in the hybrid progeny. Size of blade, number of lobes, shape of teeth and general shape of petiole sinus were most probably affected by a great number of genetic factors. Monogenic inheritance was determined with regard to the density of prostrate and erect hairs between veins on the lower side of blade. [Projekat Ministarstva nauke Republike Srbije, br.
