Prospects for the gene pool use of stone fruit plants in the distant hybridization of cherries

18 species of cherries are collected for the preservation and study in the gene pool of the station. The following species P. sachalinensis, P. kurilensis, P. pensylvanica, P. incisa, P. serrullata, P. lannesiana, P. fruticosa separated by economically valuable traits, were involved in distant hybridization as a female parent. Cherry varieties, donors of large – fruited fruit, performed as a male parent. The article shows the yielding results of interspecies crossing, the patterns of inheritance of hybrid traits of early and late emergence from the condition of a deep dormant period and winter hardiness. According to the results of our research, we recommended the following species – P. lannesiana, P. serrullata, P. sachalinensis as donors of short onset, and as for late and long-lasting – P. pensylvanica, P. incisa, P. fruticosa. Species which transmit the sign of winter hardiness to their progeny – P. fruticosa, P. incisa and P. kurilensis.
