Abstract: A new walnut rootstock cultivar‘Zhongningyi’was bred by crossing Juglans major and Juglans regia. This cultivar has well-developed root system,vigorous plant growth,distinct apical dominance,rapid growth rate,high grafting affinity. The average annual growth in trunk diameter is 1.8 cm,exceeding its parent plants by ≥ 33%. The rooting rate of green-wood cutting of‘Zhongningyi’is not less than 85%,and the bud grafting survival rate as a rootstock for walnut cultivars is not less than 97%. The grafted walnut cultivar grows strongly and has excellent disease resistance and tolerance to poor soils. This rootstock is suitable for promotion and application in the walnut-growing regions of North China,Northwest China,and East China.

Key words: walnut, rootstock, disease resistance index, cultivar
