It passed the variety registration in 2019 and was listed as the leading variety in Zhejiang Province from 2021. In the multi-point identification test in Zhejiang Province from 2015 to 2016, the average fresh potato yield per 667 m² was 2 388.5 kg, which was 10.82% higher than that of the control variety Zhongshu 3. In the multi-point demonstration of new potato varieties in spring from 2018 to 2021, the average fresh potato yield per 667 m² was 2 882.4 kg, which was 23.02% higher than that of the control variety Zhongshu 3. The highest yield per 667 m² was 3 683.3 kg in the demonstration side. The resistance of the shoots and tubers to potato late blight in the field was significantly better than that of Zhongshu 3, and the resistance to potato virus X and Y was moderate. Zheshu 956 is a medium-early maturing variety, which can be cultivated in spring and autumn in Zhejiang Province.
