Abstract: The aim of this study was to identify the ideal maize seed harvest moment by different characteristics, as black layer formation, milk line development, seed moisture content and seed dry matter accumulation. Three simple hybrids from Syngenta Company were used in this work; ears from plants in the same development stage were collected, the first harvesting began 40 days after flowering, at four days interval until all seeds in an ear had the black layer formation. The characteristics evaluated were: black layer formation, milk line development, seed moisture content and seed dry matter. Seed physiological quality was evaluated by germination test, cold test, accelerated ageing and electrical conductivity. Results obtained in this study showed that the best indicative to identify the ideal maize seeds harvest moment is milk line stage 4 (75% of solidified endosperm). This stage occurs at different time for each genotype studied, 60DAF to hybrids 1 and 3, and 52DAF to hybrid 2, due to genetic differences among the hybrids.
