Agrobiological and Economic Evaluation of the Fujiminori Grapevine Cultivar (v. Labrusca × V. Vinifera) in the Lower Don Region
Year: 2025
Type: article
Abstract: The article presents the results of a varietal study of agrobiological and economically valuable characteristics of the Japanese interspecific grapevine cultivar Fujiminori (Vi-tis labrusca L. × Vitis vinifera L.) under the conditions of the Lower Don region. Based on three-year field observations (2021–2023), it was established that the cultivar exhibits high productivity (96.8 q/ha) and large berry size (average berry weight 9.7 g), but requires win-ter protection due to limited frost resistance (critical temperature threshold -20.7°C). A de-pendence of yield quality on hydrothermal conditions was revealed: during drought pe-riods, a 10.1% decrease in sugar accumulation (from 20.7 to 18.6 g/100 cm³) and loss of berry turgor were observed. Phytopathological as-sessment showed heterogeneous resistance: 3.0 points to downy mildew, 2.5 points to gray mold, and increased susceptibility to powdery mildew (3.5-4.0 points), necessitating a diffe-rentiated protection system. Sensory analysis revealed polarized consumer preferences (average score 7.2 points), attributed to genetic variations in methyl anthranilate perception. Technological requirements include crop load regulation (fruitfulness coefficient 1.3) and gibberellin treatment. The cultivar can be recommended for niche production and amateur viticulture, where its distinctive fruity flavor and marketable qualities may offset increased cultivation costs. It targets a specific consumer segment (18–22% of total respondents) preferring pronounced fruity-berry notes. In commercial-scale production, economic efficiency will be limited by higher expenses for winter protection and disease control measures.
