Analysis of the possibilities of interbald hybridization of stone crops with the participation of Microcerasus pumila L. and receptions of its intensification

Abstract

The paper presents the results of intergeneric hybridization involving a species of Microcerasus pumila . It is shown that the use of isolated forms and already existing hybrids allows for targeted hybridization, both under greenhouse conditions and in the field. This selection direction has great prospects in creating new forms of vegetatively propagated rootstocks for peach, myrobalan, plums, etc. To intensify the selection process, a number of techniques have been proposed, such as the selection of parental forms, the cultivation of seedlings from unripe fruits, scarification, and the like.
