From a local staple in the Andes to a global food icon, the potato journey is etched deeply in the History of the Potato

The Biodiversity and Varieties of Native Potatoes

The biodiversity of native potatoes reflects their evolutionary and cultural significance, encompassing over 4,000 landraces and 107 wild species within the Solanum genus, with S. tuberosum as the primary cultivated species. Domesticated 8,000–10,000 years ago in the Andes, these potatoes thrive in microclimates from 2,000 to 4,500 meters above sea level, shaped by natural hybridizations 9 million years ago and millennia of Indigenous farmer selection.

Secondary centers in Mexico and the U.S. Southwest, such as the Four Corners region further enrich this genetic pool. The International Potato Center (CIP) in Peru catalogs over 9,700 varieties, while Bolivia Fundación Proinpa documents 2,400+ landraces, making these regions global hubs for potato diversity (Biodiversity in Potato).
