In order to increase the production of sweet cherry fruits the rootstocks are needed that are suitable for intensive orchards. The purpose of this work is to assess the selected forms of rootstocks for sweet cherry at the reproduction stage in the nursery. Under the conditions of Southern Russia, when plants are cultivated on black soil, a significant reduction in the crown of cherry trees on low-growing rootstocks is often not observed. Therefore, the assessment of breeding material requires the ranking according to habit of cherry of combinations with rootstocks under the conditions where the gardens will be laid. It is also necessary to begin the study of the characteristics of fruit crops combinations already at the stage of reproduction. Studies were conducted in the nursery of EPD �Tsentralnoye� (Krasnodar) during reproduction of the selected forms (4-33, 11-4, 4-39, 4-34, 10-18, 3-39, 11-18, 5-44, 7-42, AI 12, B 72, AI 11, B 164, AI 70, B 1). The combinations of these forms with seed material obtained from Drogana Zheltaya sweet cherry were studied. As a result of the work, the best samples for compatibility with yellow-fruit sweet cherries were identified: 4-33, 11-4, AI 12, 10-14 100 %) and 5-44, 7-42, 4-39, AI 11, AI 70, 10-18 (80-89 %). Genetic-statistic analysis revealed a significant impact of the rootstocks forms the growth and development of sampling. The share of influence in the total dispersion of the signs studied by us ranged from 44.1 % (diameter) to 83.5 % (crown shape). The ranking of combinations of rootstocks with sweet cherry on the growth vigor and diameter of sampling is carried out. The forms with the lowest plant height were selected such as 10-18, 10-14, AI 70. The greatest branching of the sampling was observed in the combinations with 5-44, B72, B1 forms.
