Abstract
The article presents the results of a comparative analysis of growth and development of trees of the Dalikatnaya variety,
 propagated on clonal rootstocks VPK-1 and 18/25, by the following parameters: crown projection area, tree height, crown
 volume, trunk cross-sectional area and dynamics of their change on during 2017–2020. On the basis of the received data
 the elite form 18/25 has been carried to group of very undersized rootstocks which on 5-6th years of cultivation in a garden
 provided productivity of the Dalikatnaya variety 21,8–22,1 kg/dr with a layout scheme of 4×2 m.
 The economic evaluation of five zoned plum varieties of different ripening terms (Venera, Kroman, Perdrigon, Stanley,
 Charadzeika), suggests that the clonal rootstock 18/25 provided a restrained growth force of trees of all studied varieties, with
 yields in 2019–2020 at the level of 14.6–20.5 kg/dr, with the average weight of the fruit 33.6–45.4 g.
 Signs of the rootstock and graft physiological incompatibility during the study period were not detected, the formation
 of root shoots was not observed. This contributed to the good development of the trees and the realization of the genetic
 potential of variety productivity and crop quality.
