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.
