Chile

Chile has a long and important association with potato cultivation, particularly because the country contains one of the world’s major centres of potato diversity in the Chiloé Archipelago in southern Chile. Potato production occurs across a wide range of environments, but commercial production is concentrated mainly in central and southern regions. The crop is an important part of the national food system and is grown largely by small and medium-scale farmers. Current information from Chile’s Office of Agricultural Studies and Policies (ODEPA) indicates that approximately 35,000–40,000 hectares are planted to potatoes annually, with most production destined for the domestic market.

The southern regions, particularly Los Lagos and the Chiloé Archipelago, are especially important for potato biodiversity and seed conservation. Chiloé has traditionally supported a remarkable collection of native potatoes adapted to the cool, humid conditions and long summer days of southern Chile. FAO recognizes the Chiloé agricultural system as a Globally Important Agricultural Heritage System because of its agricultural biodiversity and traditional farming practices. Historical records and research indicate that hundreds of native potato types have been maintained by farming communities, with women playing an important role in conserving and selecting planting material.

Potatoes are also produced commercially outside Chiloé, extending through central and southern Chile under irrigated and rainfed conditions. The crop is important for fresh consumption, seed production and processing, while Chilean breeding and conservation programmes continue to use native germplasm. The genetic resources of Chiloé are particularly significant because Chilean potato material contributed to the development of modern potato populations cultivated in Europe and other parts of the world

Potatoes were cultivated in southern Chile long before European colonization. Indigenous communities in Chiloé developed and maintained diverse potato populations through generations of selection and adaptation. Historical accounts from the colonial period describe potatoes as an important component of the local diet, while archaeological, historical and genetic evidence supports the long-standing cultivation of native potatoes in the Chiloé region. The crop became deeply integrated into Chiloé's food culture, farming traditions and community practices.

Chile's importance to global potato history became particularly evident during the 19^th century. Potato material from southern Chile was introduced to Europe, where Chilean germplasm became increasingly important after the European potato late-blight crisis of the 1840s. The long-day adaptation of Chiloé potatoes was also valuable for breeding in the Northern Hemisphere. Today, Chile's native potato diversity remains an important genetic resource for breeding, conservation and future crop improvement, although modernization, disease pressure and replacement by commercial varieties have reduced the number of traditionally cultivated types.
