It is questionable if early selection for resistance to Colletotrichum lindemuthianum reduces the efficiency of selection for grain yield in common beans. For this, it was used the segregating population of the cross between two common bean lines: CI107 (susceptible) x BRSMG Madrepérola (resistant). Selection for resistance was carried out in F2and F3, obtaining three types of progenies: not selected (A), selected only in F2(B), and selected in F2and F3(C). The progenies obtained were evaluated for grain yield and pathogen occurrence in experiments. In F3:5, it was used 289 treatments (96 progenies A, 96 B, 95 C and 2 checks (T)); in F3:6, 196 treatments (64 A, 64 B, 64 C and 4 T); in F3:7, 81 treatments (26 A, 26 B, 26 C and 3 T). Selection of plants resistant to anthracnose in early generations increases the successful selection for grain yield in later generations.</jats:p
