Investigation of Domination Degree of Mildew Resistance (Plasmopara Viticola Berl. et de Toni) and Heterosis Effect of the First Generation (Fı) Hybrids of Grape

This article deals with studying of domination degree of mildew resistance and heterosis effect of the first generation (Fı) hybrids formed of crossing of pathogen resistant (2 points) complex hybrids (SV 18-315, Zeybel 13-666, SV 12-375) with mildew resistant European-Asian (V.vinifera L.) grape varieties.
