Planting stock of fruit sapling requires the improvement of the fruit assortment, taking into account the changes in climatic factors of cultivate area. The rootstocks resistant to abiotic and biotic stressors adapted the most to local soil and climatic conditions are necessary. Therefore, this work dedicated to the selection of rootstock adaptive forms for plum-tree relevant to modern gardening. The change in the weather conditions in the Krasnodar Territory over the past 68 years is analyzed in this paper. A trend towards an increase in average daily air temperature was found. Two periods of warming over a long-term period are shown, one �in the spring, and other � in the summer months. The research carried out in the Ust-Labinsk area with frequent adverse manifestations of weather stressors, promote the forestall breeding on a number of stability indicators. The proposed materials of the article contributes to the development of resource-saving technologies involving the use of adaptive plants and environmental methods for their cultivation and reproduction. As a result of study, the adaptive plum rootstocks have been identified, which have a high percentage of rooting when growing without irrigation on a bogar, with the selection of domestic preparations that give the greatest effect of increasing in rooting rate and yield of high-quality planting stock. It was found that the most suitable for rooting under the conditions of lack of moisture and high summer temperatures are the rootstocks: BS 2, PK SK-1 and the rootstock forms of PKSK-2, 921, PKG18 / 13, PKSK-2, 921 (2), 934, 918 �13, 6p34. The significant influence of the rootstock genotypes the ability to rooting by lignified cuttings under the influence of various preparations was noted. Under these conditions the greatest effect was observed when the rootstocks forms of 934 and SC SC-2 were reproducted with using of Fitactiv Extra Kornevin B and Fitactiv Extra Kornevin A preparations.
