摘要：

- The objective of this work was to estimate genetic parameters and to select lines of carioca commercial bean group with high yield, great 100-seed weight, good grain appearance, and good resistance to fusarium wilt, disease caused by the fungus Fusarium oxysporum f. sp. phaseoli that inhabits the soil. A total of 114 lines coming from two populations were evaluated together with seven control genotypes in the winter crop season in the years/generations of 2015/F5:7 and 2016/F5:8. There is a genetic variability among the carioca common bean (Phaseolus vulgaris) lines for all the traits evaluated, and the estimates of the genetic parameters show a possible successful selection for reaction to fusarium wilt, yield, grain appearance, and 100-seed weight. Twenty-four lines of carioca common bean that were selected combine high resistance to fusarium wilt, yield, 100-seed weight, and good grain appearance. CNFC 19126, CNFC 19205, and CNFC 19131 show a better performance than the control genotypes with the highest level of resistance, so their evaluation in multiple environments is recommended, aiming at new resistant cultivars to Fusarium oxysporum f. sp. phaseoli.
