Abstract


The objective of this study was to evaluate grain yield stability and adaptability from the fixed lines and cultivars of common bean of color and black comercial groups from IAPAR’s common bean breeding program, as well as to compare  the methods of Wrick, Eberhart & Russell, Cruz et al. and AMMI. Three trials using the carioca group and two using the black group were conducted during the 2006/2007 water crop season and the 2007 dry crop season, in 27 environments in the State of Paraná. Each trial included 20 genotypes. The following genotypes were selected: LP 06 22 (G13) (carioca 1), LP 06 04 (G7) (carioca 2), LP 06 52 (G5), LP 06 54 (G7) e LP 06 65 (G18) (preto 1) e LP 06 73G9 (preto 2). All genotypes showed high grain yield potential with wide adaptability and stability. The environment more stable and more productive was Ponta Grossa – dry season for the all studied groups. As for the method comparisons, the Eberhart & Russell and Cruz et al. showed significant and positive correlation in 80% of the studied groups for genotypes stability and adaptability.
