The results of the study of clonal rootstocks of apple trees of various ecological and geographical origins, varieties of fruit, berry crops, and grapes of local selection are presented. According to the efficiency of reproduction in the mother liquor and fields of nursery formation, as well as the short stature of trees of grafted varieties in the garden, precocity and productivity, clonal rootstocks of the apple tree B7-35, Arm18, 62-396, and B16-20 were distinguished. Their important role in unlocking the potential of ancient apple varieties in the south and southeast of Kazakhstan. These rootstocks and varieties are recommended for propagation and creation of highly productive orchards. The Ministry of Agriculture of the Republic of Kazakhstan provided funding within the framework of the budget program 267 “Improving the availability of knowledge and scientific research” under subprogram 101 “Program-targeted financing of scientific research and activities” – Creation of varieties and hybrids of fruit and berry, nut crops and grapes based on the achievements of bio and IT technologies, 2021–2023yy.
