The phenotypic recurrent selection aims to increase the favourable allelic frequency during successive selection cycles, which may result in an open-pollinated variety. Therefore, the purpose of this work was to obtain an artichoke population improved for traits related with head quality as well as to estimate the genetic gains for quantitative traits after selection. From a base population with 147 plants (C0), 12 were selected for desirable characteristics for in natura consumption and intercrossed to form the C1 population, consisting of 180 plants. Eleven of them were selected and intercrossed to originate the C2 (324 individuals). From C2, 11 individuals were selected and recombined performing the C3 population. Three of these populations (C0, C1 and C2) were evaluated regarding 12 quantitative and three qualitative traits. Quantitative data were subjected to an analysis of variance (ANOVA) and mean values were compared by Tukey´s test (p
