The CIP (International Potato Center) in Lima, Peru preserves over 4,000 potato cultivars in its genebank, making it the world's largest collection of potato diversity. According to CIP records, Peru and Bolivia together harbor 3,000-5,000 native potato varieties — the greatest potato diversity on Earth.
This extraordinary concentration exists because potatoes originated in the Andes mountains of South America, specifically in present-day southern Peru and northwestern Bolivia, where they have been cultivated for 8,000-10,000 years. The diversity developed through millennia of human selection at high altitudes of 2,500-4,500 meters in the Andes.
Beyond the Andean region, Europe also maintains significant potato diversity. The European Cultivated Potato Database lists over 4,000 registered varieties across EU member states, while the broader EUROPOTATO database contains 6,199 varieties globally.
The scale of local diversity is remarkable — a single farming community in the Peruvian Andes may cultivate 50-200 distinct varieties, and these native varieties are currently grown by an estimated 1.5-2 million smallholder families across Peru, Bolivia, Ecuador, Colombia, and Argentina.
