According to the results of studying the parameters of the crown of Golden Delicious apple tree plantations on clone rootstocks M 9, MM-106 and K 104, it was found that the K 104 tree is in the middle position be-tween M 9 and MM-106 in terms of growth strength. The cross-sectional area of the eight-year-old tree trunk on it is 68,4 cm2 . In the control variant, this value is 63,4 and 73,6 cm2 , respectively. The height of the trees on K 104 is 0.2-0.3m higher than on M 9 and 0,2-0,3m less than on MM-106. The growth of trees depends on the functioning of the root system, the development of which, in turn, is due to a number of factors the strength of the growth of rootstocks and varieties grafted on them, the planting scheme and growing conditions. The purpose of the research was to establish the mutual influence of tree aboveground part growth indicators on different rootstocks and the size of their root system. In our studies, it was determined that the most developed root system was in trees on K 104 rootstock, where the total number of roots was 417 pcs., which is 41 pcs. higher than in trees on MM-106 and 87 pcs. more than on M 9. The main mass of roots, 58.3% is located in the soil horizons of the 40-60 cm, while the root system of trees on a weak-growing rootstock M-9 is characterized by occurrence, mainly in the upper soil layers up to 40 cm. In the total mass of the roots of all rootstocks, the fraction up to 1 mm thick is 87.6-95.8 %. The relationship between the size of the underground and the above-ground parts of the trees, depending on the rootstocks, was established: the area of the root system was 1.3-1.7 times larger than the area of the crown.

Natural conditions of Crimea are favorable for the successful cultivation of a variety of fruit, berry and other crops. In this region, horticulture is one of the priority branches of the agro-industrial complex the main task of which is to provide the population with fruits, berries and their derived products. The most important direction in improving the efficiency of Crimean horticulture is its further intensification using clonal rootstocks, highly productive varieties and technological developments adapted to the conditions of growth. The article presents an overview and results of a long-term study of rootstocks, varieties, their combinations and methods of cultivating the competitive, headed planting material of fruit crops. A new clon-al rootstock K104 was selected and included in the State Register of Selection Achievements Approved for Use, which by force of growth, occupies an intermediate position between M9 and MM106 and does not require the installation of an expensive trellis. Slightly growing clonal rootstocks KA 61, KA 86, KA 53, KA 92 for pear were created, resistant to high content of CaCO3 in the soil (up to 30%). The productivity of these rootstocks in the mother plantation is 20-30 % higher than that of VA 29; in the garden by 25-30 %. By fast ripening and high yielding, the rootstocks for peach BBA-1 and Evrika 99 in combination with varieties of Veteran and Redhaven were distinguished. Among the seed rootstocks, GF-305 distinguished itself. Intensive gardening presupposes the mandatory transfer of the industry to a virus-free basis. It is established that the yield capacity of plantings planted the material healthy from the main virus diseases is higher by 25-30 %.
