Resumo

A study was made of the Fp generation of diallel crosses between different classes of relative weight of seeds of the corn variety 'Maya 50'. The influence of these various weights were analyzed using the Fj of the crosses and their reciprocals. Characteristics studied were percent protein and percent lysine in both the endosperm and the germ, and the ratio of lysine to protein in the endosperm.
