China

China is one of the world’s major potato producing countries, with cultivation extending across a remarkably wide range of climates, from the cool, dry northern plains and highlands to the subtropical and mountainous southwest. Potato production is concentrated particularly in northern and southwestern China, where the crop fits well into dryland, highland and mixed cropping systems. Major production areas include Inner Mongolia, Gansu, Guizhou, Yunnan, Sichuan, Heilongjiang, Shanxi, Shaanxi and Ningxia.

China’s potato sector is divided into distinct production systems according to climate and cropping season. Northern China is dominated by single season production, particularly across Inner Mongolia, Gansu, Ningxia, Shanxi, Heilongjiang and surrounding areas. Central China supports double cropping systems, while southwestern provinces such as Yunnan, Guizhou and Sichuan benefit from altitude and diverse climates that allow potatoes to be integrated into mixed and multiple-cropping systems. Southern China also produces winter potatoes, including on land following rice, allowing farmers to supply markets during periods when potatoes are less available from northern production areas.

Potatoes are important both as a food crop and as a source of income for rural communities, particularly in mountainous and semi-arid areas where other crops may face limitations from poor soils, water scarcity or short growing seasons. China’s industry includes fresh market potatoes as well as processing for starch, crisps and French fries. Improvements in improved seed production, breeding, mechanization, storage and processing are increasingly important as the industry moves toward higher productivity and greater commercial integration.

The potato is not native to China; it originated in the Andes of South America and spread to Europe before reaching Asia. Historical sources generally place its arrival in China during the 17^th century, with potatoes probably reaching coastal areas through European maritime trade and being introduced into parts of central China through Russian traders. The crop gradually spread beyond its initial areas as farmers recognized its ability to produce food under conditions where traditional cereals could be more difficult to grow.

During the Qing Dynasty and subsequent centuries, potatoes became increasingly valuable as a food security crop, particularly in northern and mountainous areas. Production expanded substantially during the 20^th century and China emerged as the world's largest potato producer. FAO sources report that Chinese potato production increased nearly fivefold between 1961 and the early 2000s. In the modern industry, research institutions and international organizations have supported breeding, seed potato multiplication, disease management and improved production technologies. The release of varieties such as Jizhangshu 8, developed from the Tacna variety and released nationally in 2006 after trials in northern China, illustrates the role of breeding for drought tolerance and yield stability in expanding potato production.
