Research results of the influence of interstocks on fruit yield of varieties Antej and Telisaare apple trees for age-specific periods, and the study results of specific indices of yield load depending on the interstock vigour are concerned. The semi-dwarf interstocks 3-3-35, 3-6-47, 3-17-27 and the dwarf interstocks B 9, N 134, P 22 have been studied. The cropping for both varieties Antej and Telisaare was higher on the interstock 3-3-35. For the varieties Antej and Telisaare on the dwarf interstocks specific fruit load of the trunk cross sectional area, crown projection area and leave surface area was higher by 1,5 times than for the same varieties on the semi-dwarf interstocks. When comparising the same variants of varieties Antej and Telisaare on specific fruit load results of crown projection area (per unit area) it is clear that in control variant this index at variety Antej was more in 1,4 times, and variants with interstocks 3-3-35 and 3-17-27 - in 1,6-1,9 times more than in analogous variants at variety Telisaare. Specific indices of fruit load of the apple trees of variety Antej on variants were higher by 2 times in comparison with variety Telisaare
