Summary: This study aimed to evaluate the agronomic behavior of 22 cacao half-sib families over 3 years, considering the yield components and resistance to the fruit borer and witches' broom. The characteristics were interpreted using analysis of variance with a split-plot model, with the effects of families on the plot and years on the subplot. Estimates of genetic parameters and the non-parametric Lin?Binns test were used to quantify adaptability and stability. The results indicated a high genetic variability among the evaluated progenies. The progenies AM 1090, AM 1066, AM 1070, AM 1077, and AM 1085 showed better adaptability and stability over the years in terms of yield. AM 1068, AM 1081, AM 1091, AM 1095, and AM 1097 exhibited better performance for witches' broom resistance, whereas AM 1077, AM 1081, AM 1085, AM 1088, and AM 1112 exhibited better performance for fruit borer resistance.
