"Nine Andean species with edible roots and tubers play a major
role in potato-based farming systems. These crops are of great
economic and nutritional importance to subsistence Andean
farmers, and are often used as substitutes for expensive fruits
and vegetables in the diet. They are known in the Quechua Indian
language as achira, ahipa, arracacha, maca, mashua, mauka,
oca, ulluco, yacón."
