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. 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. After the disastrous European Potato Failure in the 1840s strains originating in the Chiloé Archipelago replaced earlier potatoes of Peruvian origin in Europe. The potatoes of Chiloé are important elements of Chilote folk medicine and features in Chilote mythology. Historian Renato ...

Potato
The potato is a starchy food, a tuber of the plant ''Solanum tuberosum'' and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations,University of Wisconsin-Madison, ''Finding rewrites the evolutionary history of the origin of potatoes'' (2005/ref> but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the ''Solanum brevicaule'' complex. Lay summary: In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated. Potatoes were introduced to Europe from the Americas by the Spanish in the second half of the 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andrés Contreras
Andrés Nicolás Contreras Méndez (d. November 30, 2014) was a Chilean agronomist known for his studies of the native potatoes of Chiloé. Contreras pioneered preservation efforts of the many varieties of Chiloé potatoes as he began in the 1960s to travel Chiloé Archipelago in search of small gardens where local elderly women had grown potatoes over many generations. In 1990 he led a potato-hunting expedition to Guaitecas Archipelago; the southern limit of Pre-Hispanic agriculture. San Juan de la Costa was another location where he collected potatoes. Contreras improved local varieties intended to be used in small scale agriculture in Chiloé and San Juan de la Costa. Contreras established the gene bank of Chilean potatoes at the Austral University of Chile in Valdivia Valdivia (; Mapuche: Ainil) is a city and commune in southern Chile, administered by the Municipality of Valdivia. The city is named after its founder Pedro de Valdivia and is located at the confluence of the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytophthora Infestans
''Phytophthora infestans'' is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by '' Alternaria solani'', is also often called "potato blight". Late blight was a major culprit in the 1840s European, the 1845–1852 Irish, and the 1846 Highland potato famines. The organism can also infect some other members of the Solanaceae. The pathogen is favored by moist, cool environments: sporulation is optimal at in water-saturated or nearly saturated environments, and zoospore production is favored at temperatures below . Lesion growth rates are typically optimal at a slightly warmer temperature range of . Etymology The genus name ''Phytophthora'' comes from the Greek –(), meaning : "plant" – plus the Greek (), meaning : "decay, ruin, perish". The species name ''infestans'' is the present participle of the Latin verb , meaning : "attacking, destroying", from which ...
