Resumo: | The objective of this work was to evaluate the adaptability and the grain yield stability of 16 cowpea (Vigna unguiculata (L.) Walp.) genotypes using the additive main effects and multiplicative interaction model. The trials were carried out at nine environments, locations and years, of the Middle-North region of Brazil, states of Piauí (PI) and Maranhão (MA), in the period from 1999 to 2001. Environments and genotype x environment interaction effects, and the first two axes of the analysis of principal component of the interaction were significant (P < 0.01). The analysis of principal components explained 61.25% of the sum of squares of the genotype x environment interaction. TE93-244-23F and TE93-210-12F-1 genotypes gathered genes for adaptability and stability, and can be cultivated in all environments. BR 17-Gurguéia, Canapuzinho and EPACE-10 genotypes presented the highest yield averages, but were unstable and with specific adaptation to environments of high quality. The environments more favorable were Bom Jesus, PI, 2000; Palmeira do Piauí, PI, 2001, and Sambaíba, MA, 2000. There was no tendency of locations grouping by State and the distribution was balanced in terms of environmental quality. |

Walp.) utilizando o modelo de efeitos aditivos principais e interação multiplicativa. Os ensaios foram realizados em nove ambientes, locais e anos, da região Meio-Norte do Brasil, Estados do Piauí (PI) e Maranhão (MA), no período de 1999 a 2001. Os efeitos de ambientes e interação genótipos x ambientes, e os dois primeiros eixos da análise de componentes principais da interação foram significativos (P < 0,01). A análise de componentes principais explicou 61,25% da soma de quadrados da interação genótipos x ambientes. Os genótipos TE93-244-23F e TE93-213-12F-1 reuniram genes para adaptabilidade e estabilidade, os quais podem ser cultivados em todos os ambientes. Os genótipos BR 17-Gurguéia, Canapuzinho e EPACE-10 apresentaram as maiores médias de produtividade, mas foram instáveis e com adaptação específica a am-bientes de alta qualidade. Os ambientes mais favoráveis para a produtividade de grãos foram Bom Jesus, PI, 2000; Palmeira do Piauí, PI, 2001 e Sambaíba, MA, 2000. Não houve tendência de agrupamento de locais por Estado e a distribuição foi equilibrada em termos de qualidade ambiental.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFilho, Francisco Rodrigues FreireRibeiro, Valdenir QueirozRocha, Maurisrael de MouraLopes, Ângela Celis de Almeida2003-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6612Pesquisa Agropecuaria Brasileira; v.38, n.5, maio 2003; 591-598Pesquisa Agropecuária Brasileira; v.38, n.5, maio 2003; 591-5981678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6612/3669info:eu-repo/semantics/openAccess2014-07-31T17:48:28Zoai:ojs.seer.sct.embrapa.br:article/6612Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-31T17:48:28Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
