Resumo: We evaluated eighteen commercial corn hybrids recommended for the South Central region of Parana and eighty-one hybrid combinations obtained between them in a circulant diallel, along with a witness. The objective was to assess the general combining ability (GCA) and specific combining ability (SCA) between eighteen commercial corn hybrids recommended for the South - Central region of Paraná, for agronomic traits and nutritional qualities of silage by selecting Diallel analysis of maize hybrids the best and the best hybrid combinations for the synthesis of new populations in order to produce grain and silage of high nutritional value and investigate correlations among traits. The design was evaluated in 10 x 10 lattice with three replications and each unit consisted of three rows of five meters each, was conducted at the experimental campus in CEDETEG Guarapuava and Farm Touros in Candói. Were evaluated for grain yield, plant height, height of ear insertion in both local and was assessed Guarapuava production of green matter, dry matter production, dry matter, acid detergent fiber, neutral detergent fiber, digestibility in vitro dry matter and crude protein. The first two rows of each plot were evaluated for yield, as well as plant height and height of ear insertion, the third line had been harvested when the grains in the hard dough stage, they were weighed twenty - five plants to obtain production of green, from six plants for silage, and subsequently determining the qualitative characteristics in the laboratory. Data were subjected to analysis of variance and individual and joint diallel analysis. A joint analysis was significant effect of GCA and SCA, there was significance between the GCA x environment interaction for all traits, since the SCA x environment interaction was not significant for grain production. Regarding the GCA effects for feature five hybrids PG SG6015, P30K64, P30B39, and 2B688 GNZ2004 estimates showed positive and high GCA for both sites, since the hybrid CD304 showed the highest negative GCA. Qualitativ e characteristics for the experimental design was randomized blocks with three replications. In diallel analysis was demonstrated genetic variability for all traits. Highlight the hybrids CD304, P30B39, AS1572, AS1560 and P30F53 showed that IVDMD CGC positive and negative for ADF and NDF. For PB the hybrid combinations SG6010 x AS1572, AG5011 x SG6010 e AG8021 x AS1551 were organized in the group of higher crude protein content. Regarding the PMV and PMS iv values found in this study were similar to those reported in literature for the southern region. It can be concluded that the hybrids have evaluated the potential for obtaining the base populations for improvement of maize.

It can be concluded that the hybrids have evaluated the potential for obtaining the base populations for improvement of maize. Diallel analysis showed to be efficient to identify the best hybrids and the hybrid combinations that yield and qualitative characteristics associated with favorable silageForam avaliados dezoito híbridos comerciais de milho recomendados para a região Centro Sul do Paraná e oitenta e uma combinações híbridas obtidas entre elas em esquema de dialelo circulante, juntamente com uma testemunha. O objetivo do trabalho foi avaliar a capacidade geral de combinação (CGC) e capacidade específica de combinação (CEC) entre dezoito híbridos comerciais de milho recomendadas para a região Centro - Sul do Paraná, para caracteres agronômicos e bromatológicos da silagem, selecionar por meio de análise dialélica os melhores híbridos de milho e as melhores combinações híbridas para a síntese de novas populações visando à produção de grãos e de silagem de alto valor nutritivo e verificar correlações entre os caracteres avaliados. O delineamento foi avaliado em látice 10 x 10 com três repetições e cada parcela constituída de três linhas de cinco metros cada, foi conduzido na área experimental do campus CEDETEG em Guarapuava e na Fazenda Touros em Candói. Foram avaliadas produção de grãos, altura de planta, altura de inserção de espiga em ambos os locais e em Guarapuava foi avaliado produção de matéria verde, produção de matéria seca, teor de matéria seca, fibra em detergente ácido, fibra em detergente neutro, digestibilidade in vitro da matéria seca e proteína bruta. As duas primeiras linhas de cada parcela foram avaliadas a produtividade de grãos, assim como altura de plantas e altura de inserção de espiga, a terceira linha foi colhida quando apresentava seus grãos no estádio farináceo duro, foram pesadas vinte e cinco plantas para a obtenção da produção de matéria verde, selecionadas seis plantas para serem ensiladas, e posteriormente determinação das características bromatológicas em laboratório. Os dados foram submetidos a análise de variância individual e conjunta e análise dialélica. Na análise conjunta foi verificado efeito significativo da CGC e da CEC, foi verificada a significância entre a interação CGC x ambientes para todos os caracteres avaliados, já a interação CEC x ambiente não foi significativa para produção de grãos. Em relação aos efeitos da CGC para a característica PG cinco híbridos SG6015, P30K64, P30B39, GNZ2004 e 2B688 apresentaram estimativas positivas e elevadas da CGC para ambos os locais, já o híbrido CD304 apresentou maior CGC negativa. Para as características bromatológicas o delineamento experimental utilizado foi em blocos ao acaso com três repetições. Na análise dialélica foi evidenciado variabilidade genética para todas as características avaliadas. Destaque aos híbridos CD304, P30B39, AS1572, AS1560 e P30F53 que apresentaram CGC positivas para DIVMS e negativas para FDA e FDN. Para PB as combinações híbridas SG6010 x AS1572, AG5011 x SG6010 e AG8021 x AS1551 foram organizadas no grupo de maiores teores de PB. Com relação a PMV e PMS os valores encontrados nesse estudo foram semelhantes aos mencionados na literatura para a região Sul do país. Pode se concluir que os híbridos comerciais avaliados apresentam potencial para obtenção de populações base para melhoramento do milho forrageiro. A análise dialélica mostrou-se eficiente para identificar os melhores híbridos e as combinações híbridas que associaram produtividade e características bromatológicas favoráveis da silagemMade available in DSpace on 2016-09-20T12:12:29Z (GMT).
