Commercial and consumer properties of sweet cherry cultivars of the RRIFCB bioresource collection

The article presents the results of studying the commodity and consumer qualities and properties of common sweet cherries (Prunus avium L.), which are a part of the RRIFCB bioresource collection. The research was carried out on the basis of the laboratory of selection and variety study of stone fruit crops of RRIFCB in the period from 2013 to 2022. As objects of research, both cultivars bred on the basis of RRIFCB and cultivars that were introduced from other research institutions were used. Both qualitative and quantitative commodity and consumer qualities of sweet cherries were considered. The first category included such indicators as color of the fruit, shape of the fruit, shape of the stone, nature of the detachment of the fruit, density of the pulp, color of the juice. The category of quantitative indicators includes such indicators as average weight of the fruit, average weight of the stone, score of the fruit taste, length, thickness and width of the fruit. As a result of the research, it was found that most cultivars have commercial and quality qualities of fruits suitable for sweet cherries. Cultivars Poeziya and Donetsky Velikan can be used in cherry breeding as a source of large fruit. All the studied varieties of sweet cherry are recommended for use in breeding for a high content of fruit pulp. Cultivars Poeziya, Adelina, Donetsky Velikan and Sweet cherry from Donetsk are sources of high palatability of fruits for sweet cherry breeding. The sources of large fruit sizes in cherry breeding are cherry cultivars Poeziya, Adelina, Donetsky Velikan and Alyonushka.
