The objective of this research was to evaluate the common bean lines developed by the Embrapa Rice and Beans Research Center, concerning stability, adaptability, resistance to diseases and other desirable agronomic characteristics. The lines were divided in two experimental groups, one including 216 black grain lines, and the other with 56 color grain lines (Carioca and Mulatinho), both groups with four check varieties. The experimental design was the Federer's augmented blocks. The environmental indexes (Ij), the regression coefficients (bi), and their deviation variances (s2di) were obtained using the Eberhart & Russell's (1966) method. Among the 56 color grain lines, 40 showed stable performance, and among the 216 black grain lines, 49 were considered stable. The mean grain yield for the CNFP10080 line, which belongs to the black grain group, was significantly higher (p KEY-WORDS: Phaseolus vulgaris; disease resistance; plant breeding; grain yield.
