Resumo: The objective of this work was to estimate the repeatability of adaptability and stability parameters of common bean between years, within each biennium from 2003 to 2012, in Minas Gerais state, Brazil. Grain yield data from trials of value for cultivation and use common bean were analyzed. Grain yield, ecovalence, regression coefficient, and coefficient of determination were estimated considering location and sowing season per year, within each biennium. Subsequently, a analysis of variance these estimates was carried out, and repeatability was estimated in the biennia. Repeatability estimate for grain yield in most of the biennia was relatively high, but for ecovalence and regression coefficient it was null or of small magnitude, which indicates that confidence on identification of common bean lines for recommendation is greater when using means of yield, instead of stability parameters.

Os dados de produtividade de grãos provenientes de ensaios de valor de cultivo e uso de feijoeiro-comum foram analisados. A produtividade de grãos, a ecovalência, o coeficiente de regressão e o coeficiente de determinação foram estimados quanto a local e época de semeadura por ano, dentro de cada biênio. Posteriormente, realizou-se análise de variância destas estimativas, e a repetibilidade foi estimada nos biênios. Aestimativa de repetibilidade quanto à produtividade de grãos, na maioria dos biênios, foi relativamente alta, mas, quanto à ecovalência, ao coeficiente de determinação e ao coeficiente de regressão, foi nula ou de pequena magnitude, o que indica maior confiança na identificação de linhagens de feijão a serem recomendadas, quando se usam as medidas de produtividade, em vez dos parâmetros de estabilidade.Empresa Brasileira de Pesquisa Agropecuária - EMBRAPA2020-11-04T19:26:36Z2020-11-04T19:26:36Z2013-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfLIMA, L.
