Eight genotypes resulting from five recurrent selection cycles of Solanum tuberosum were evaluated, using the design of random complete blocks with three repetitions. There are highly significant differences in total weight and total tubers of different genotypes in six environments. Combined analysis detected significant differences for environments, genotypes, and IGE. The locality effects, genotypes, genotypes x locality and genotypes x environment were highly significant. The best environmental indices for weight of total tubers and tubers were achieved in the towns of: Santa Clotilde, La Pucara, Marcobamba and Santa Margarita. Genotype 399062.115 was considered stable, consistent and high yield potential 46.01 t ha-1. Genotypes: 396012.266 and 393377.159 with yields of 42.01 t ha-1 and 38.66 t ha-1, responded better to unfavourable and consistent conditions.
