Abstract: The investigation on the influence of apple hardy dwarfing rootstocks on growth and fruiting habit of the scion cultivars was conducted for five years. The results showed that the compatibility of the scion culti-vars (Jinhong and Hanfu) grafted on various rootstocks(M.Robusta，M Micro}nalus baccata Borkh，inter-stocks，M Toringozdse var Xiaojinensis)was different，hardy dwarfing interstocks 77-34, GMZS6 and M Torzngoidse var Xiaojinenszs show the best compatibility. They were dwarfed, early fast-growing, exhibiting lower tree/crown width ratio, early blossoming, and early bearing in the young apple trees.Compared to ar-borous rootstocks(M. Robusta，M Micromalus baccata Borkh)，the early output was obviously increased, and the fruit quality was remarkably improved. Using 77一34 and GMZS6 as inter rootstocks and M Toringoidse var. Xiaojinenszs as hardy dwarfing rootstocks on apple were the best in cold regions.
