Walnut is an important cultivated tree with high economic value and wide distribution across China. The objective was to breed a new walnut cultivar with high yield and desirable nut and tree qualities that could meet the demands of the walnut industry in China. 'Liaoning 4' walnut cultivar is lateral bearing which originated from a controlled cross between the Persian walnut () selections 'Liaoning Chaoyang big and rough walnut' and '11001'. During long term assessment and research, 'Liaoning 4' walnut performed well and it was released as a new cultivar in China on 15 Oct. 2018. It has a high yield and excellent nut traits and has thus been widely planted in North China.
