Productive potential and interaction of elite bean lines with environments in the Central Cerrado of Brazil

Abstract

The search for more productive varieties of beans, with lower production cost and adaptable to mosttechnological conditions has been intensified. The objective of this study was, therefore, to evaluate the stabilityand adaptability of common bean lines of the carioca group in the final evaluation network in the CentralCerrado of Brazil, in 2005 and 2006. Twelve lines and four cultivars were evaluated in 23 environments. Acompletely randomized block design was used with three replications, with plots of four rows of four meters. Grain yield data were subjected to analysis of variance, stability and of adaptability by the methodologies of Lin and Binns, Annichiarico and visual assessment, respectively. The most stable and promising lines for recommendation as new cultivars were CNFC 10429, CNFC 10431 and CNFC 10408.
