The data of study of rootstocks for large-fruited crops (plum, cherry plum, apricot) of breeding of SCFNCHVW and Stavropol breeding station are given. Their ability to root on heavy loamy soils with the use of the Fitaktiv Extra growth stimulator was studied. According to the results of monitoring the implementation of planting material, it has been established that now the combinations of plum grafted on rootstocks with a well developed root system providing strong fixation in the soil and allowing the mechanized harvesting are most in demand. In the Krasnodar Territory there are not enough soils suitable for fruit growing, therefore, the creation of rootstocks for stone fruit crops that can normally develop on wetland heavy loamy soils is very important breeding direction, that will significantly allow to increase the area of the gardens. The study carried out revealed the rootstocks that grow and develop poorly under the conditions of dense soils with high moistening and perish for several years. Therefore, it can be assumed that the plants isolated in the experiments on high rooting, good growth and development, as well as on a high score of the general state, can be evaluated as resistant to the stressors listed above. We also established that in the conditions of Goryacheclyuchevskoy district of the Krasnodar Region, the further research on the selection of optimal highly profitable scion-rootstock combinations of the stone fruit crops is necessary with the use of selected (according to the general state, the number of roots and the percentage of rooting) of the rootstocks 534 D and 935/6. The positive effect of the Fitaktiv Extra preparation on obtaining a quality planting rootstocks material for large stone fruit crops was noted.
