Abstract: The purpose of this study was to identify ‘Carioca’ common bean genotypes high yield adaptability and stability in central South Brazil, based on different analysis methods. The value of cultivation with and use (VCU) of 16 genotypes was evaluated in 26 trials in a randomized complete block design with three replications, in the states of Santa Catarina, São Paulo and Paraná, in 2003 and 2004. Grain yield data were subjected to analysis of variance, of stability and adaptability, using the methodologies of Lin and Binns, Annichiarico, Eberhart and Russell, Cruz et al. and AMMI. Several of the methodologies indicated the genotypes BRS Estilo and CNFC 9518 for high yield, high adaptability and high stability. The yield, stability and adaptability of cultivar Pérola, widely grown in the country, were lower than of the new elite genotypes obtained by the breeding programs.
