Descrição: A common bean (Phaseolus vulgaris L.) breeding program aims to obtain high yielding lines with quality bean seeds, disease resistance, and upright plant growth habit. The aims of this study were to evaluate the resistance of 527 common bean lines to the principal physiological races of Colletotrichum lindemuthianum and the Fusarium oxysporum f. phaseoli; to estimate genetic parameters and verify the efficiency of the genealogical and bulk methods in conducting these lines. Of these 527 lines, 279 were conducted by the genealogical method and 248 by the bulk method. For the field experiment, the Federer augmented block experimental design was used. Two commercial cultivars carioca seed coat were used as controls for the lines the same color, and more two commercial cultivars for the black seed coat lines. The traits evaluated in the field were plant height (PH), plant growth habit (P), bean seed yield (BY), sieve yield (SY), and lightness of the bean seed coat (L). Of the 527 lines evaluated for anthracnose, 207 were resistant, 57 moderately resistant, and 263 susceptible. For fusarium wilt, 58 were resistant, 53 moderately resistant, and 96 susceptible. For the carioca seed coat lines obtained by the genealogical method, the heritability (h (2) ) estimates stood out for P, BY, L at 40 d, and gain from selection for BY. The h (2) stood out for black seed coat lines in the PH and SY traits, it can be concluded that the lines obtained by the genealogical method had better performance for all the traits. Key words: Anthracnose, autogamous plant breeding, fusarium wilt, gain from selection, heritability, Phaseolus vulgaris.
