The gene pool of the black apricot - Prunus dasycarpa Pers. and its use in stone fruit crops breeding

Abstract

The article presents the results of research aimed at studying varieties, forms and hybrids of black apricot – Prunus dasycarpa Pers., preserved in the gene pool of the Krymsk EBS, VIR Branch, and identifying the feasibility of including genotypes of this species and hybrid seedlings in breeding programs to create new adaptive varieties with high fruit quality and easy vegetative reproduction of clonal rootstocks of stone fruit crops. It was revealed that cross-species hybridization of black apricot with stone fruit crops, in particular apricot and cherry plum, allows to create adaptive genotypes suitable for cultivation, as well as being a valuable source material for further breeding use. For production use, the varieties of the Krymsk EBS breeding are of interest: black apricot - Kubansky Cherny (45234)*, Cherny Barkhat (45235)*, Kolibri (45240)*, Plemkot Kubansky (26217)*; Russian plum Globus (43854)*; clonal rootstock Alab 1 (18213)* (*VIR catalogue No.).
