English: Potato (Solanum tuberosum L., 1753) of the genus Solanum (L., 1753) of the family Solanaceae (Juss., nom. cons., 1789) is a widespread agricultural crop. The major cultivars are autotetraploid subspecies. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile. It is grown for the tubers that form on underground stolons. Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots. Fruits are berries, similar to small tomatoes. Contains the poison solanine. The concentration of poison in the flesh of the tuber is low, in the skin and eyes is higher, in the berries - even higher.
