Besides the anthracnose resistance, the objective of this research was to identify lines with Carioca grain type, high grain yield, angular leaf spot resistance (Phaeoisariopsis griseola), and upright plant architecture. Two hundred and fifty six lines from a backcross breeding program aiming to get anthracnose resistance lines were evaluated. Four field trials were set up in three places of the Minas Gerais State, and grain type and yield, reaction to angular leaf spot and plant architecture were measured. Great genetic differences were observed among the lines and therefore, the heritabilities estimates were also of great magnitude and assure considerable selection progress. The majority of the phenotypic correlation among the evaluated traits were not significant, suggesting the possibility to select improved lines for all traits. Five superior lines were selected, with high grain yield, Carioca grain type, angular leaf spot resistance and upright plant architecture which could become new cultivars. Two of them have a pyramid of anthracnose resistance alleles.
