Resumo: | For the agricultural year of 1998, data from a network of experiments using a randomized block design with three replications for 25 corn cultivars and 30 hybrids cultivated in nineteen and sixteen different environments, respectively, were analysed, aiming to obtain knowledge concerning to adaptability, and yield stability of cultivars in each environment. The hybrids showed an average performance 21.4% higher than the cultivars. In the experiments involving cultivars and populations, the Cargill hybrid 909 utilized as control, had a higher yield either under unfavorable or favorable environments. The yield of AL 30, BR 5028, BR 106, BR 5011, BR 5033, "Sintético Dentado", "Sintético Duro" cultivars and the CMS 50 population expressed good adaptation and yield stability under Northeastern Brazil conditions. In the experiments with hybrids, Dina 1000, Cargill 333 B, Dina 270, Braskalb XL 360, Master, AG 1051, AG 4051 and Pioneer 3041 expressed adaptation and yield stability higher than the other hybrids tested under the different environmental conditions. At favorable environmental conditions, the hybrids AG 4051 and Pioneer X 1296 B were the best ones. Even though no hybrids were specifically indicated for unfavorable environment, the recommendation of materials showing higher yields at unfavorable environments are interesting for the corn grower. This is the case of the Dina 1000, Cargill 333 B and Braskalb XL 360. |

Durante o ano agrícola de 1998, na Região Nordeste do Brasil, foram realizados experimentos em rede, em blocos casualizados com três repetições, envolvendo a avaliação de 25 cultivares (cultivares e populações) e de 30 híbridos de milho em dezenove e dezesseis ambientes, respectivamente, objetivando conhecer adaptabilidade e estabilidade dessas cultivares para fins de recomendação. Os híbridos apresentaram maiores rendimentos, em média, 21,4% mais que as cultivares. Nos ensaios envolvendo cultivares e populações, o híbrido Cargill 909, utilizado como testemunha, teve um rendimento superior, tanto nos ambientes desfavoráveis quanto nos favoráveis. As cultivares AL 30, BR 5028, BR 106, BR 5011, BR 5033, Sintético Dentado, Sintético Duro e a população CMS 50 expressaram boa adaptação e estabilidade de produção no Nordeste brasileiro. Nos ensaios envolvendo híbridos, Dina 1000, Cargill 333 B, Dina 270, Braskalb XL 360, Master, AG 1051, AG 4051 e Pioneer 3041 apresentaram maior adaptação com estabilidade de produção nos ambientes considerados. Para recomendação específica a ambientes favoráveis destacaram-se os híbridos AG 4051 e Pioneer X 1296 B. Apesar de não se encontrarem híbridos com adaptação específica a ambientes desfavoráveis, a recomendação de materiais com maiores rendimentos nesses ambientes é de interesse para o agricultor, a exemplo do Dina 1000, Cargill 333 B e Braskalb XL 360.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCarvalho, Hélio Wilson Lemos deLeal, Maria de Lourdes da SilvaCardoso, Milton JoséSantos, Manoel Xavier dosCarvalho, Benedito Carlos Lemos deTabosa, José NildoLira, Marcelo AbdonAlbuquerque, Marcondes Maurício2001-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6178Pesquisa Agropecuaria Brasileira; v.36, n.4, abr. 2001; 637-644Pesquisa Agropecuária Brasileira; v.36, n.4, abr. 2001; 637-6441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6178/3243info:eu-repo/semantics/openAccess2010-08-09T12:47:47Zoai:ojs.seer.sct.embrapa.br:article/6178Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-09T12:47:47Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
