The cultivation of potatoes in Peru is the main source of income and food for small producers in the high Andean areas. For new potato cultivars to be adopted and disseminated after their release, it is necessary to apply methodologies such as participatory varietal selection (PVS), in which all the actors of the crop value chain participate. During the years 2016-2017, three potato clones were evaluated: CIP393079.4 (Flor Blanca), CIP387096.2 (Shulay), CIP396034.268 and the cultivars Unica and Canchan, in eight locations in the regions of Huanuco, Junin and Huancavelica in Peru. The sowing of the experiments in randomized complete block design (DBA) with three repetitions was carried out between the months of September to November 2016 and the harvest between the months of March and June of 2017. The selection criteria were, at the flowering: resistance to late blight, abundant foliage and tolerance to drought; at harvest they were: high yield, uniform size and tubers health. At flowering, clones CIP396034.268 and CIP393079.4 were selected by the farmers. The men also selected the clone CIP387096.2, while the women, in addition to the first two clones, selected the cultivar Canchan. To the harvest, the producers selected clones CIP396034.268, CIP393079.4 and CIP387096.2 respectively in the three regions. Clones CIP387096.2, CIP393079.4 and CIP386034.268 were more resistant to late blight than the Canchan and Unica cultivars in the regions of Huancavelica, Huanuco and Junin.
