Zusammenfassung: | The search for more productive varieties of beans, with lower production cost and adaptable to most technological conditions has been intensified. The objective of this study was, therefore, to evaluate the stability and adaptability of common bean lines of the carioca group in the final evaluation network in the Central Cerrado of Brazil, in 2005 and 2006. Twelve lines and four cultivars were evaluated in 23 environments. A completely 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.
A procura por cultivares de feijão mais produtivas, com menor custo de produção e adaptadas as mais variadas condições tecnológicas tem aumentado. Assim, o objetivo deste trabalho foi avaliar a estabilidade e adaptabilidade das linhagens de feijoeiro comum do grupo carioca em ensaios da rede de avaliação final de feijoeiro-comum no cerrado central do Brasil, anos de 2005 e 2006. Foram avaliadas 12 linhagens e quatro cultivares testemunhas em 23 ambientes. Foi empregado o delineamento de blocos completos casualizados com três repetições, sendo as parcelas constituídas de quatro linhas de quatro metros. Os dados de produtividade de grãos foram submetidos a análises de variância e de estabilidade e adaptabilidade pelas metodologias de Lin and Binns, Annichiarico e Visual. As linhagens CNFC 10429, CNFC 10431 e CNFC 10408 mostraram-se mais estáveis e promissoras para indicação como nova cultivar. |
