Resumo: One of the greatest concerns on maize breeding throughout the years has been to increase production without reducing nutritional quality. The present study aims to evaluate F2 maize populations with normal endosperm and their crosses, as related to total grain protein content and determining heterosis and its components. The method used for protein content determination was proposed by AOAC ";Official methods of analysis";, adapted and used by CIMMYT (International Center for Maize and Wheat Breeding). The statistical diallelic analysis of data was carried out through the Gardner and Eberhart's model IV (1966). The fundamental operation for parameter estimation as well as for sums of squares calculation was the ordinary minimum squares. It was observed significance for all effects of the adopted model. For the trait total grain protein content, the best genitors were AG-6690 and ZN-8486, and the best hybrid combination was P30K75 x AG-6016. KEY-WORDS: Protein content; corn; normal endosperm; diallel crosses.

Uma das maiores preocupações do melhoramento genético do milho, ao longo dos anos, foi aumentar sua produção, sem diminuir sua qualidade nutricional. Este trabalho objetivou avaliar populações F2 de milho com endosperma normal e seus cruzamentos, quanto ao teor de proteína total, determinando-se a heterose e seus componentes. A metodologia utilizada para as determinações da proteína total no grão foi aquela proposta pela AOAC "official methods of analysis", a qual foi adaptada e adotada pelo CIMMYT (Centro Internacional de Melhoramento de Milho e Trigo). A análise estatística dos dados foi realizada pelo modelo IV de Gardner & Eberhart (1966), para análise de cruzamentos dialélicos. A operação fundamental para estimação dos parâmetros, bem como para cálculo das somas de quadrados, foi a determinação de quadrados mínimos ordinários. Observou-se significância para todos os efeitos do modelo adotado. Destacaram-se, para o caráter teor de proteína total no grão, os genitores AG-6690 e ZN-8486, bem como a combinação híbrida P30K75 x AG-6016. PALAVRAS-CHAVE: Proteína total; milho; endosperma normal; cruzamento dialélico.
