STUDY OF WHITE GRAPE VARIETIES PROMISING FOR NON-COVERING CROPS UNDER ECOLOGICAL CONDITIONS OF KBR

Abstract

The article is devoted to the substantiation of the expediency of the production introduction in the regions of the Central Ciscaucasia of white varieties of non-covering culture of European and domestic selection. The distribution schemes, growth and development of grapes, indicators of disease resistance, frost resistance, productivity, and crop quality are described. A comparative analysis of 10 white technical grape varieties being tested at Concern ZET LLC is carried out to identify new, frost-resistant grape varieties suitable for non-covering own-root crops on alluvial-meadow soils. The basis of the study is a long-term production experience of cultivation of varieties of different selections in areas with different soil conditions. The purpose of the research was to identify the most promising grape varieties of a non-covering crop with stable fruiting and stable crop quality parameters for the subsequent expansion of their introduction into production in the regions of the Central Ciscaucasia, for the development of new areas suitable for grapes, mainly in non-covering culture.
