Abstract
The purpose of this work was to estimate combining ability of 58 sorghum lines previously selected for Aluminum (Al) tolerance. One hundred sixty-five F1 hybrids were developed by crossing fifty-five male sterile lines with three restorer lines. Hybrids were evaluated at three level of Al saturation (0%, 20% and 40%). Environment with 0% of Al saturation yielded 43% more than that with 40% of Al saturation, showing the importance of genotype selection for acid soils. General Combining Ability (GCA) effects were significant for female lines and not significant for male lines. Considering the germplasm evaluated, the ration GCA and Specific Combining Ability (SCA) was higher than the unity, indicating the prevalence of the additive effects for the control of the Al tolerance. Female lines were identified with high GCA for yield. These included F20, F21, F48, F54 and F55 with GCA higher than 900 Kg ha-1.
