Summary: | Although corn silage be sufficiently known, the availability of these materials in the market is low, demonstrating that specific breeding programs in this area are scarce. Thus, the aim of this study was to determine the predominant type of gene action in controlling the characteristics and estimate general (GCA) and specific combining (CEC) among commercial corn hybrids aimed at producing corn. The eight hybrids and 56 hybrid combinations were evaluated in crop year 2011/2012, in the town of Gurupi, located in southern Tocantins. The experimental design used was 8 x 8 lattice with two replications and analyzed three characteristics of commercial interest for the production of corn for silage. The hybrid combinations responded differently to combinations of capabilities, when subjected to conditions of low and high phosphorus availability, as evidenced by the significant effects of the interactions. This indicates that the selection should be performed in environments where they will be used. We conclude therefore that the hybrid P 30F53Y had higher concentration of favorable alleles in enhancing the features and PMS PMV being more suitable in the formation of new hybrids, combinations AG in 2040 x TRUCK, TRUCK AG 8060 and AG 1051 x x IMPACT was higher heterotic effect, these being the most suitable hybrids for silage. The dominant gene in this analysis is due to additive effects. |

Deste modo, objetivou-se com este trabalho determinar o tipo de ação gênica predominante no controle das características e estimar a capacidade geral (CGC) e específica de combinação (CEC) entre híbridos comerciais de milho visando à produção de silagem. Foram avaliados 8 híbridos comerciais e as 56 combinações híbridas foram avaliados no ano agrícola de 2011/2012, no município de Gurupi, localizados na região sul do Tocantins. O delineamento experimental utilizado foi o de látice 8 x 8 com duas repetições, sendo analisadas três características de interesse comercial para a produção de milho para silagem. As combinações hibridas apresentaram divergências frente a sua capacidade de combinação, quando submetidas às condições de baixa e alta disponibilidade de fósforo, evidenciado pelos efeitos significativos das interações. Isso indica que a seleção de híbridos comerciais de milho deve ser realizada em ambientes onde os mesmos serão utilizados. Conclui-se, portanto que o híbrido P 30F53Y possui maior concentração de alelos favoráveis ao incremento das características produção de massa verde e seca, sendo a mais indicada na formação de novos híbridos; nas combinações AG 2040 x TRUCK, AG 8060 x TRUCK e AG 1051 x IMPACTO houve maior efeito heterótico, sendo estes híbridos os mais indicados à produção de silagem. Para a maioria das características a principal dominância gênica é devida aos efeitos aditivos.Universidade Federal de Viçosa - UFV2017-11-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/68910.13083/reveng.v25i5.765Engineering in Agriculture; Vol. 25 No. 5 (2017); 381-395Revista Engenharia na Agricultura - REVENG; v. 25 n. 5 (2017); 381-3952175-68131414-398410.13083/reveng.v25i5reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/689/pdfMelo, Aurélio Vaz deTaubinger, MarkusSantos, Valdere Martins dosCardoso, Dione PereiraNunes, Helber Verasinfo:eu-repo/semantics/openAccess2023-01-19T13:33:09Zoai:ojs.periodicos.ufv.br:article/689Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:33:09Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
