Abstract
The presence of anthocyans was studied to determine the anthocyanin profile as a tool for distinguishing grapes of the Don region of autochthonous and hybrid varieties of ARRIVW breeding and other hybrid varieties for isolation and identifying typical characteristics. The composition of anthocyans depends on both the variety and the grape habitat. The presence of 3.5-diglucosides in hybrid varieties was established.
Highlights
The achievements of viticulture and winemaking are aimed at promoting new varieties for cultivation in more northern territories
This crossing leads to the change in the anthocyanin profile: 3-glycosides of anthocyanidins are supplemented with 3,5-diglucosides
The purpose of the research was to study the chromatographic profiles of anthocyans in the berries skin of red grape varieties growing in the Rostov region
Summary
The achievements of viticulture and winemaking are aimed at promoting new varieties for cultivation in more northern territories. Since the beginning of the 20th century, rootstocks imported from North America have been widely used in Europe to give a certain resistance against phylloxera to European varieties of the Vitis vinifera L. species [1, 2]. Operations of crossing grapes of other species (Vitis labrusca L., Vitis amurensis Rupr., etc.) allowed to obtain new varieties that are resistant to diseases, low temperatures and other factors. This crossing leads to the change in the anthocyanin profile: 3-glycosides of anthocyanidins are supplemented with 3,5-diglucosides
