Abstract: In order to select a suitable walnut rootstock for Sichuan hilly regions, this study used 10 type of 9 species walnut rootstocks were used for the study of variety charaeteristics and the graft compatibility. The result showed that the emerging time of different walnut rootstocks was similar. The emergence rate of Juglans sigillata was the highest and Pterocarrya stenoptera was the lowest. The leaf index of P. stenoptera was maximum and the leaf index of kazi walnuts and thumb walnut of gulin were minimum. The graft compatibility of J. nigra was the highest when Shuoxing walnut was used as scion. And the graft compatibility of J. sigllata was the highest when Naingqing walnut was used as scion.
