Resumo: Twelve commercial maize hybrids were intercrossed in a complete diallel. These genotypes and three checks were evaluated in lattice design with three replications in the South-Central region of Parana State, in Laranjeiras do Sul, Guarapuava and Cantagalo. Data of yield of husked ear, plant height and ear height were submitted to joint diallel analysis according to Griffings method 4, i.e. only F1 were evaluated. Significant effect was found for general combining ability (GCA), specific combining ability (SCA) and interaction ‘GCA x locations’ for all characters. The interaction ‘SCA x location’ was not significant for both characters. Hybrids P30F53 and AS1575 showed positive and high estimates of GCA for yield of husked ear and high mean of yield, being interesting for the generation of populations with potential for intrapopulation breeding to obtain superior lines. The hybrids P30F44 and 2B688 are potentially indicated to generate populations for interpopulational breeding, since their high in yield of husked ears, positive GCA and SCA estimates, besides favorable estimates for ear height.

Esses genótipos e três testemunhas foram avaliados em látice triplo na região Centro-Sul do Paraná, nos municípios de Laranjeiras do Sul, Guarapuava e Cantagalo. Os dados referentes à produção de espigas despalhadas, altura de planta e altura de espiga foram submetidos à análise dialélica conjunta, segundo o método 4 de Griffing, em que foram avaliados apenas os F1. Foi verificado efeito significativo da capacidade geral de combinação (CGC), da capacidade específica de combinação (CEC) e da interação ‘CGC x locais’ para todos os caracteres. A interação ‘CEC x locais’ foi não significativa para as características avaliadas. Os híbridos P30F53 e AS1575 apresentaram estimativas positivas e elevadas da CGC para peso de espigas despalhadas e alta produtividade, mostrando-se promissores para geração de populações com bom potencial para obtenção de linhagens superiores no melhoramento intrapopulacional. Os híbridos P30F44 e 2B688 apresentam potencial para a geração de populações para melhoramento interpopulacional, pois apresentaram elevada média da produtividade de espigas despalhadas, estimativas positivas da CGC e da CEC, além de estimativas favoráveis para altura de espiga.UEL2013-03-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campo - experimentaçãoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/774910.5433/1679-0359.2013v34n1p7Semina: Ciências Agrárias; Vol. 34 No. 1 (2013); 7-18Semina: Ciências Agrárias; v. 34 n. 1 (2013); 7-181679-03591676-546Xreponame:Semina.
