Tree size plays a key role in yield and management, affecting production costs and driving orchard efficiency. Three Budagovsky (B.9, B.10 and B.7-20-20), five Geneva (CG.4814, CG.4214, G.935, G.41 and G.11) and two Malling (M.9T337 and M.26) rootstocks with 'Honeycrisp' as the scion cultivar were used for this trial. The most dwarfing rootstock was B.9, while G.11, B.10, G.41, M.9 and M.26 were slightly larger. The next larger group was CG.4214, G.935 and CG.4814. B.7-20-20 was much more vigorous than all other rootstocks. Higher yields were attained with CG.4814, CG.4214, B.10 and G.41, whereas the lowest values were observed for B.9 and M.26. The most yield efficient rootstocks were B.9, G.11, B.10 and G.41.
