Biology:Potatoes of Chiloé
The Chiloé Archipelago is home to a wide variety of potatoes. After the Titicaca region of Peru and Bolivia, it is the geographical nucleus where the most different types of potatoes are found. Evidence ranging from historical records, local agriculturalists, and DNA analyses strongly supports the hypothesis that the most widely cultivated variety of potato worldwide, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.[1][2] Contrary to potatoes from Peru and Bolivia the potatoes of Chiloé are adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.[1] Local varieties include Camota, Cielo, Pachacoña, Cabrita, Chelina, Guadacho Colorada, Zapatona, Michuñe Azul, Huicaña and Ñocha.
Guaitecas Archipelago
Some of the potatoes of Chiloé also grow in the wild in Guaitecas Archipelago, although there is some uncertainty as to when and how potatoes arrived there.[3] The Guaitecas Archipelago formed the southern limit of Pre-Hispanic agriculture[4] as noted by the mention of the cultivation of potatoes by a Spanish expedition in 1557.[3] Later during the second voyage of HMS Beagle, Charles Darwin collected potatoes from Guaitecas.[3]
Potatoes grow beside the sea in a herbaceous zone. The wild potatoes that grow in the archipelago are mostly found in its western part. Apparently these potatoes do not reproduce by seeds and rarely produce flowers and fruits.[3] Potatoes grow in zones of disturbance, mainly in the herbaceous zone near the coast that is affected by winter storms.[3]
