This study evaluated the agronomic performance of six segregating populations of black bean (BRS Supremo x CHP 97-01, BRS Supremo x CHP 97-04, BRS Supremo x CHP 97-05-16, BRS Supremo x CHP 97-26, BRS Supremo x IPR Graúna and BRS Supremo x Uirapuru IPR) in the F3 generation, conducted by the bulk method. Populations and parents were evaluated in the 2007/08 growing season in a randomized block design with four replications. Results show promising traits of the segregating population BRS Supremo x CHP 97-04, which was superior to parent BRS Supremo, indicating the line for further selection. The segregating populations and their parents were grouped by Ward’s method, indicating the similarity of the selected lines.
