Not only its crown but also its growth is medium. The internode is 2.3 cm long .The survival rate grafing on the rootstock（Pingyi Tiancha）is 88.2%,while that on the cultivar is 100%. The growth of the 3-years-old dwarfing interstock is 278 cm,while the nursery rate is 88.2%. Grafting on the interstock,The ratio of the trunk of the rootstock/interstock is 1.18,while that of the cultivar/the interstock is 0.81. The grafting union is not swelling,without air root,which shows it has high grafting affinity. Grafing on the interstock in high yield year,The Fuji tree has a 3.80 m height and a 3.63 m crown diameter. It belongs to a semi-dwarfing rootstock which is similar to M7. 26.7% of the Fuji grafting on the interstock begin to produce at 2 years old. The average yield of the tree of 7–14 years old is 43 140 kg · hm-2. The soluble solids content of the Fuji is 14.3%,the hardness is 8.1 kg · cm-2,and the fruit index is 0.85,which is suitable for the application in the main dwaring apple production area such as Shandong,Shaanxi,Shanxi,Henan and Hebei.
