Anatoli Iliev, Miroslav Ivanov

Резюме: The paper has presented the results of a three-year study on the resistance to low winter temperatures under laboratory conditions of three wine varieties of different genetic origin grafted to four different rootstocks. The wine varieties were Rubin (Vitis vinifera L.) and Storgozia and Kaylashki Rubin obtained through interspecific hybridization. The varieties were grafted to the following rootstocks: American-American hybrids – Berlandieri x Riparia SO4, Berlandieri x Rupestris 110 Rihter, Riparia x Rupestris x Cordifolia 44-53 Malegue and European-American hybrid – Ferkal (/Berlandieri x Colombard/ X /Cabernet Sauvignon x Berlandieri/).
