In this study, we analyzed heterosis, amylase enzyme gene expression, and the physiological quality of maize seeds with dif­ferent genotypes and sizes, which were subjected to aging and not sub­jected to aging. We used seeds from 2 maize lines that differed with regard to physiological quality, the hybrid, and the reciprocal hybrid; they were classified into 2 sizes and were subjected to aging and not subjected to aging. Physiological quality was assessed by performing tests for germination, emergence, emergence speed index, and artifi­cial aging.
