This map shows the global distribution of potato production (in tonnes). The biggest potato producer in the world during 2007 is China, followed by Russia and India.

Potato has a long history in human society and it grows almost anywhere. It has probably originated in the Andes in South America. Most of the wild and cultivated species are from Peru.

The major species grown worldwide is Solanum tuberosum. Potato is rich in starch and is one of the most important food crops. It also contains multiple minerals and vitamins.

Potato can also grow in relatively harsh condition compared to other major crops. It is therefore ideal for developing countries, where land and resources are limited. It is recommended as food security crop that can help low-income farmers and consumers.

圖示世界各國馬鈴薯生產量(以噸計)。二零零七年,中國是全世界馬鈴薯生產量最大的國家,其次是俄羅斯及印度 。

馬鈴薯在人類社會有悠長歷史,種植遍及全球。其發源地相信是南美的安第斯山脈。一般野生及培養品種集中在秘魯。

最常見的馬鈴薯品種是Solanum tuberosum.它含豐富的澱粉質並且是重要食用農作物之一種,它還含有多種礦物質和維生素。

與其他農作物比較,馬鈴薯可以在一個相對惡劣的環境下生長。這對於一些土地和資源缺乏的發展中國家較為有利。馬鈴薯可作為糧食保障農作物,有助支援低收入的農民和消費者。
