Fruit growing
and viticulture of South Russia

Annotation

The article presents the results of assessing the biological potential of sweet cherry varieties in the garden grafted on seed and clone rootstocks. Biometric records were carried out: indicators of the diameter of the stem, crown and height of trees, fruit ripening dates, their weight and market condition. The biochemical composition of sweet cherry fruits has been studied. The objects of research were sweet cherry varieties of different maturation periods of the Voronezh State Agrarian University and scientific institutions of the Russian Federation breeding; seed and clone rootstocks. For an objective assessment of variety-rootstock combinations of sweet cherry, studies were carried out in accordance with generally accepted methods when working with fruit crops and methodological guidelines for the determination of chemicals for assessing the quality of the yield of vegetable and fruit crops. The purpose of the study was the selection of winter-hardy, high-yielding varieties of sweet cherry grafted on low-growing clonal rootstocks to create small-sized intensive plantings and introduce them into industrial gardening in the Central Chernozem region. From the analysis of the obtained results of the study, the selective features of variety-rootstock combinations of sweet cherry are noted, manifested in the features of the growth force and fruiting. High-yielding varieties were established, the qualitative indicators of fruits and their biochemical composition were determined, with the allocation of highly fortified varieties for breeding work. Variety-rootstock combinations for planting gardens of intensive type have been identified. The best variety-rootstock combinations of sweet cherry have been propagated and introduced into the industrial gardening of a specialized enterprise ZAO �Ostrogorzhsksadpitomnik� of the Ostrogorzhsky district of the Voronezh region
