Most of the Russian Federation zones has a continental climate and significant amplitude of temperature fluctuations in the autumn-winter and spring periods are one of the most urgent problems of wintering the grape plants. The conducted researches showed that among the introduced varieties of grapes, studied in the conditions of the Omsk region, the two groups of varieties with a degree of freezing of eyes are distinguished in the average for 2012-. 2016 years at the level of the control grade Katyr (26.3%) - Ayar -27.3, Tukay - 31.5%; the freezing is higher than the control grade level in the following varieties: GF -2-7-2 - 42.2, Agat Donskoy - 47.6, Edna 48.1, Moscovityanin -53.3%. The prospects for growing grapes in trench culture in the Omsk region are varieties with a relatively stable and potentially high productivity, such as Tukay, Edna, an average of 5.2 and 5.0, a maximum of 8.8 and 11.4 kilogramm per bush, and Agat Donskoy and GF -2-7-2, an average of 4.9 and 4.7, a maximum of 12.4 and 10.1 kilogramm per bush. The results of overwintering of grapes in trench culture largely depend on the presence and height of the snow cover, it is recommended to use additional insulation of trenches over the polyethylene coating with a layer of sawdust or humus in conditions of the Omsk region in the absence or a small snow cover.
