%X Richness of farmer varieties of tuber species cultivated by 28 peasant households was monitored in communities of Cajamarca and Hu¨¢nuco, Peru during four consecutive agricultural cycles (from 2001 to 2005). In-depth interviews were conducted with 12 of the households with higher reputation as conservationists, in order to document farmers' perception of tubers qualities in ecological, social, economic, technological and culinary aspects and how these influence their decisions of conservation priorities. Traditional varieties were identified according to their local names, which were then confronted among farmers and with scientific catalogues in order to identify synonyms. Based on the information documented, indexes of ecological and socio-cultural factors affecting agricultural practices were designed, and their linear correlations and multivariate relations with varieties richness managed per household were analyzed in order to explore factors with higher influence on conservation of crop variation.A total of 1483 and 507 farmer varieties of tuber species were found in the whole sample and period studied in Hu¨¢nuco and Cajamarca, respectively. Significantly more varieties managed per household per year were recorded in Hu¨¢nuco (146.39 ¡À 12.02) than in Cajamarca (44.55 ¡À 9.26), and marked differences in number of varieties per year were documented among households within each region (78.25 to 246.50 in Hu¨¢nuco, 7.50 to 144.00 in Cajamarca). Correlation and multivariate analyses identified that the extent of agricultural area managed by households, cultural identity, practicing of traditional agricultural techniques, and level of self-sufficiency, are meaningful factors influencing higher varieties richness maintained by households. Yield and culinary attributes were considered by people as main features for selecting and deciding which varieties are priorities for conservation.Maintenance and promotion of indigenous Andean culture is crucial for ensuring conservat
