SELECTION OF TABLE GRAPE VARIETIES FOR CULTIVATION IN KHARKIV REGION

Abstract

In Ukraine, there are relatively small areas occupied by table grape varieties, within 15% of the total area of vineyards, and the existing zoned assortment in terms of itsagrobiological and technological indicators does not quite meet the requirements of the market. For the soil and climatic conditions of Kharkiv region, the issue of selecting table grape varieties remains relevant.The purpose of the research was to select the most productive table grape varieties adapted to the soil and climatic conditions of Kharkiv region.The research was conducted during 2022-2023 at the Revik farm, located in Zmiiv district of Kharkiv region.The following varieties were studied: Arkadiya (control), Kishmysh 342, Kodryanka, Talisman.It was found that the maximum number of clusters was provided by the Kodryanka variety 35.8 pcs/bush, which is 5.8 pcs./bush more compared to the control. The smallest number of clusters was obtained on the bushes of the Talisman variety 24.5 pcs/bush. The maximum fruiting coefficient, as well as the number of vines, was obtained on the bushes of the Kodryanka variety 0.71 pcs/vine, which is significantly more compared to other varieties. The bushes of the Talisman variety had the lowest value – 0.39 pcs/vine.No significant difference was noted between the Arkadiya and Kishmysh 342 varieties.It was proven that the Kodryanka variety formed the maximum number of clusters of 25.8 pcs/bush, which was significantly more compared to other varieties. Thus, with the control variety, the difference was 5.9 pcs/bush. The smallest number of clusters was noted on the bushes of the Talisman variety – 9.4 pcs/bush.On average, during the study period, the largest average mass of the cluster was obtained for the Talisman variety – 1083 g, which is 375 and 423 grams more compared to the Kishmysh 342 and Kodryanka varieties, respectively.The bushes of the Arkadiya variety had a somewhat smaller value of the analyzed indicator compared to the Talisman variety – 766 g. The smallest mass of the cluster was noted for the Kodryanka variety – 660 g.It was confirmed that the cultivation of the Kodryanka variety provides maximum yield – 19.7 t/ha. The control variety Arcadia has a significantly higher yield compared to the varieties Kishmish 342 and Talisman.Therefore, in the soil and climatic conditions of the Left-Bank Forest-Steppe of Ukraine, we recommend growing table grape varieties such as Kodryanka and Arkadiya, which provide maximum yield per unit area.
