The objectives of this study were to estimate genetic parameters for agronomic and nutritive value traits for leaves and stems of Brachiaria humidicola progenies and to compare the selection using an additive index considering the agronomic traits alone or combined with the main nutritive value traits. Fifty progenies of the cross cv. BRS Tupi x H31 were evaluated. The experiment was arranged in a randomized block design with eight replications. The forage was cut seven times, at intervals of 30 - 35 days in the rainy season and two intervals of 60 days in the dry season. Trait variability among the progenies was confirmed. The mean progeny heritability ranged from 49.14% to 75.56% for the agronomic and from 19.59% to 71.11% for nutritive value traits. Nine of the ten best lines coincided in the selection for agronomic traits alone and in the selection including the main traits of nutritive value.
