Abstract: ‘Zhongningqiang’is a new walnut rootstock cultivar derived from‘Juglans major’× ‘Juglans regia L.’. It is a hybrid walnut cultivar with excellent characteristics,such as better stem- straightness,development of root system,higher divarication capability,fast-growing,drought resistance,leanness resistance and better graft compatibility. The diameter growing quantity is 1.7 cm every year,is 1.7 multiples of‘Juglans regia L.’. The rooting rate of green-wood cutting of ‘Zhongningqiang’is 85%. Used‘Zhongningqiang’as the stock,used‘Juglans regia L.’varieties as grafting scion,the branch grafting survival rate of‘Zhongningqiang’is more than 90%,the bud grafting survival rate of‘Zhongningqiang’is up to 95%. And the walnut is growing luxuriantly,the kernel of the nut is good taste. It is suitable for the application in the main walnut production area such as North China,Northwest China,East China and Southwest China.
