Comparative analysis of the main agrobiological indices of some early table grape varieties from the Azov Zonal Experimental Viticulture and Winemaking Experiment Station
Research work on the study of agrobiological characteristics of grape varieties of all maturation periods and their yield is carried out annually for many years. In 2018-2019 a table early varieties breeding of Usosweb showed good results, especially in terms of yield. This was favored by weather conditions. As a result of agrobiological studies and comparative evaluation of the yield of some early table grape varieties selection Anapa zonal experimental station of viticulture and winemaking - a branch of the North Caucasus Federal research center for horticulture, viticulture and winemaking and classic varieties found that, despite the dry summer of 2018, varieties selection Anapa experimental station gave a high yield and slightly surpassed in this indicator known classic varieties. This is also confirmed by data from previous years. Analysis of berries on sugar content shows the superiority of early table varieties of Muscat azos, Lotus, White early selection Anapa zonal experimental station over the classic long-known varieties such as Russian early, Madeleine Anzhevin, Early Magaracha. The data obtained confirm the high biological capabilities of early table grape varieties of the Anapa zonal experimental station selection.
