【Abstract】 The new potato variety Jingzhangshu No.3（Mid-late fresh consumption）was selected from the hybrids with844（female）and Saturna（male）by Zhangjiakou Academy of Agricultural Sciences in 2011. It was developed by pedigree method after successive generational selection and identification. Its plant type is semi-erect with green stems and leaves, and the growth period of the variety is 92 days. The corolla is white color and nearly pentagon in shape.The tuber of the variety is oval shape with smooth light medium yellow skin, medium yellow flesh and shallow bud eyes. The number and the weight of tubers per plant are 4.3 and 0.79 kg respectively. And the rate of commercial tubers is 81.2%.The average yield is 2 384.3 kg per 667 m2. The dry matter content of the tubers is 19.7 g · 100 g^-1, while starch content,reducing sugar content, crude protein content and vitamin C content are 14.4 g · 100 g^-1, 0.35 g · 100 g^-1, 2.10 g · 100 g^-1and31.6 mg · 100 g^-1respectively. The variety is moderate resistant to late blight, while it is resistant to light mosaic virus and heavy mosaic virus. This variety is suitable for planting in northern Hebei, Inner Mongolia, Shanxi, Shaanxi and other northern mono-harvesting farmlands. It was registered as GPD Potato（2021）130076 through the Ministry of Agriculture and Rural Affairs of the People’s Republic of China for non-major crop varieties in 2021.更多还原
