Resumo: | The objective of this work was to evaluate statistical methods of genotype by environment interaction (GE) analysis, emphasizing phenotypic adaptability and stability. Observed data of soybean grain yield were used, which were obtained from variety trials carried out in seven environments in Goiás State. Twenty eight genotypes were evaluated in each trial, and four of them were commercial varieties. The methods evaluated were Traditional, Plaisted & Peterson, Wricke, Finlay & Wilkinson, Eberhart & Russell, Verma, Chahal & Murty, Toler, AMMI (additive main effect and multiplicative interaction), Hühn, Annicchiarico and Lin & Binns. In order to study the association among the methods, the correlation of Spearman was used. Plaisted & Peterson and Wricke methods were always strongly associated, contraindicating their concomitant use. The Annicchiarico and Lin & Binns methods also showed high correlation between themselves producing, therefore, very similar genotypic classifications. Thus, the simultaneous use of these procedures is not also recommended. The use of one of them, however, is counseled. In the case of methods based exclusively on regression coefficients, it should be considered their association to other method, based in the variance of the GE interaction, or the introduction of statistical measures as the variance of the regression deviations. The joint use of Eberhart & Russell method and AMMI analysis is another recommendation, because their significant correlations with most of the other methods, and of a low correlation between them. |

Utilizaram-se dados de produtividade de grãos de soja de sete experimentos em Goiás, testando 28 genótipos, dos quais quatro cultivares comerciais. Avaliaram-se os métodos Tradicional, Plaisted & Peterson, Wricke, Finlay & Wilkinson, Eberhart & Russell, Verma, Chahal & Murty, Toler, AMMI (additive main effect and multiplicative interaction), Hühn, Annicchiarico e Lin & Binns. Avaliou-se a associação entre os métodos pela correlação de Spearman. Observou-se forte associação entre os de Plaisted & Peterson e Wricke, cujo uso concomitante foi contra-indicado. A mesma conclusão é atribuída aos métodos Annicchiarico e Lin & Binns, também fortemente associados, o que implica em classificações fenotípicas muito semelhantes. O uso de um deles, entretanto, é recomendado. Métodos baseados, exclusivamente, em coeficientes de regressão, devem ser utilizados em associação com outro, fundamentado na variância da interação GxA, ou em medidas estatísticas como a variância dos desvios da regressão. O uso combinado do método de Eberhart & Russell e AMMI é outra indicação, em razão de suas correlações significativas com a maioria dos outros métodos e uma associação relativamente fraca entre eles.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Waldir Camargos Júnior eDuarte, João Batista2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7101Pesquisa Agropecuaria Brasileira; v.41, n.1, jan. 2006; 23-30Pesquisa Agropecuária Brasileira; v.41, n.1, jan. 2006; 23-301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7101/4146info:eu-repo/semantics/openAccess2014-09-23T19:47:10Zoai:ojs.seer.sct.embrapa.br:article/7101Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-23T19:47:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
