Stability and adaptability of carioca common bean genotypes in states of the central South Region of Brazil

Abstract

The purpose of this study was to identify ‘Carioca’ common bean genotypes with high yield adaptability andstability in central South Brazil, based on different analysis methods. The value of cultivation and use (VCU) of 16 genotypeswas evaluated in 26 trials in a randomized complete block design with three replications, in the states of Santa Catarina, SãoPaulo 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 themethodologies indicated the genotypes BRS Estilo and CNFC 9518 for high yield, high adaptability and high stability. Theyield, stability and adaptability of cultivar Pérola, widely grown in the country, were lower than of the new elite genotypesobtained by the breeding programs.
