History - -

The earliest cultivation of potatoes in captivity can be traced back to about 8000 BC to 5000 BC. Research initiated by the University of Wisconsin in the United States, through the use of genetic markers on 350 different types of potatoes, eventually determined that potatoes all over the world originated from potatoes grown in the region where southern Peru is located today, from where they gradually spread out to the north and south of South America.

With the Spanish conquest of the Inca Empire, the potato was brought back to Europe by the Spaniards in the second half of the 16th century and spread. It was then taken around the world by European explorers and colonizers. In the early days when the potato was introduced to Europe, it was not consumed in large quantities. When the potato was introduced to British Ireland, it was even viewed as an exotic flower for a long period of time.

By the time of Europe's population expansion in the 19th century, the potato had become an important food and crop. Conservative estimates suggest that the introduction of the potato was responsible for at least a quarter of the population growth in the Old World between 1700 and 1900, as well as contributing to the urbanization of Europe.

It is difficult to determine exactly when and where the potato was introduced to China. According to the county records of Xingping County, Shaanxi Province, and Songxi County, Fujian Province, revised in the 1700s, potatoes were introduced to China from the 16th to the 19th centuries through a variety of routes from northwestern and southern China, respectively.

Based on the records and writings of the Ming Dynasty, some scholars also believe that potatoes were introduced to China as early as the 16th century during the Wanli reign of the Ming Dynasty. Potatoes were introduced to Taiwan by the Dutch in the 17th century, and professional cultivation of potatoes in Taiwan began around 1914.
