The genetic patterns of potato distribution indicate that the potato probably originated in the mountainous west-central region of the continent. According to Dr. Hector Flores, the most probable place of origin of potatoes is located between the south of Peru and the northeast of Bolivia.
Over 4,000 varieties of native potatoes grow in the Andean highlands of Peru, Boliva, and Ecuador. Selected over centuries for their taste, texture, shape and color, these potato varieties are very well adapted to the harsh conditions that prevail in the high Andes, at altitudes ranging from 3,500 to 4,200 meters. Farmers generally produce these native varieties with minimal or no use of agrochemicals.
