Given is the analysis of the basic economic and useful features of 9 genotypes F2 by hybrids of russian cherry plum (Prunus cerasifera var. pissardii) in the conditions of the forest-steppe of the southern Urals. On the research period during, three selection forms: ‘Alma’, G 7-116, 9266 had a degree of freezing to 1.8 mark, the others no more than 1.0 mark. During the winter period of 2017/18, the death of generative buds by all genotypes was from 2.5 to 3.0 marks (25-50 %), which negatively affected to crop capacity. According to the results of research identified were four genotypes with weak growth of tree, which the height varies from 2.8 m (P 3-92) to 3.0 m (‘Duduka’). The group of medium-sized plants got five hybrid forms, where the highest plant height (4.5 m) was found by the genotype 9-266 – 4.5 m. The volume of the crown of the following forms varies from 4.2 m3 (P 3-92) to 17.8 m3 (9-266). Two genotypes have been identified for use in selection on a complex of attributes (large-fruiting, taste characteristics, crop capacity): ‘Duduka’, G 7-116. For the study of production was selected the sampling of the sort G 7-116.
