The study of commercial and consumer indicators of hybrid forms of sour cherry of the RRIFCB

This article presents the results of long-term research on the commercial and consumer qualities and properties of hybrid forms of sour cherry ( Prunus cerasus L. ), bred at the RRIFCB. The research was carried out on the basis of the laboratory of breeding and variety study of stone fruit crops of the RRIFCB in the period from 2014 to 2020. Ten hybrid forms of sour cherry were taken as objects of the research. The authors studied the qualitative and quantitative commercial and consumer properties of sour cherry fruit. The first group of indicators included such qualities as the color of the fruit and juice, the shape of the fruit and the stone, the nature of the detachment of the fruit, the density of the pulp. The group of quantitative indicators included such properties as the average weight of the fruit and stone, the average percentage of pulp, the assessment of the taste of the fruit in points, the size of the fruit (length, thickness and width). According to the research results, it was revealed that most of the forms had commercial and consumer qualities of fruit suitable for sour cherries. Forms 66865, 49667, 16579, 57473 and 41059 can be used later in the sour cherry breeding as a source of high fruit weight. Cherry forms 84735, 41059, 16579, 57473, 49667 and 66865 can be used in breeding for increased pulp content. Forms 66865, 41059, 16579, 49667, 57473, 84595 and 84854 can serve as sources of high palatability for sour cherry breeding. Forms 66865, 49667, 57473, 41059 and 16579 can be used as sources of large sizes.
