Selection of carioca type common bean lines with anthracnose and angular leaf spot-resistance.
Objective of the present study was to select common bean lines with the traits anthracnose and angular leaf spot-resistance, high yield, Carioca type grains and an upright plant type. One hundred and fifty-three lines were selected from five segregating families derived from backcrosses using G2333...

| Resumo: | Objective of the present study was to select common bean lines with the traits anthracnose and angular leaf spot-resistance, high yield, Carioca type grains and an upright plant type. One hundred and fifty-three lines were selected from five segregating families derived from backcrosses using G2333 (donor parent) and the lines ESAL 696 and CI 140 (recurrent parents). The lines were evaluated and selected in three seasons under inoculation with the races 2047, 1545 and 81 of C. lindemuthianum and also tested with the SCAR marker of allele Co-5. Lines with high grain yield, Carioca type grains, upright plant type, and anthracnose-resistance were selected. The SCAR marker was not effective for the selection of resistant lines with Co-5 allele. No angular leaf spot-resistant lines were identified. |
