In Peru, potatoes with pigmented pulp have a great scientific and biological value, are cultivated and preserved in areas very localized by small farmers. The behavior of potato clones with pigmented pulp was analyzed in Llama, Cajamarca, in order to obtain high production varieties of minitubers called "baby potatoes". For this, twenty clones were selected from the hybridizations between native cultivars of Cajamarca with native ecotypes. Regarding the number of tubers per plant, the best clones were: BN4-C-1 skin color and cream pulp, BN14-C-8 skin and cream pulp, BN3-A-4 red skin and yellow flesh and BN14 -V-2 skin color and violet pulp, with 90.73, 42.9, 36.87 and 31.14 tubers per plant. In addition, these clones had the highest number of non-commercial tubers per plant with 57.50, 13.87, 13.07 and 10.07, number of stems per plant with 3.33, 3.43, 2.40 and 2.93, respectively. Being these clones those that obtained greater number of minitubers for the commercialization and human consumption like baby potato.
