Abstract: Abstract: [Objective] The dehydration rate after corn grain physiological maturity had a significant impact on the corn yield, quality, storing and processing in northern China. The dehydration rate was an important goal on suit mechanical harvest variety breeding. [Method] This study has been collected and processed research about corn grain dehydration rate in recent years, summarized the overall research on dehydration rate of corn grain from three side, that were dehydration rate differences through different varieties, correlational analyses among the grain dehydration rate and agriculture and quality traits, QTL for dehydration rate of maize kernel, provided the use resource on higher yield, quality and fast dehydrating rate about maize variety breeding. [Result] Combined research laws on corn grain dehydration, had presented the selective breeding of corn grain quality improvement. [Conclusion] The results provided reference frame for high yield, quality and fast dehydration rate at maize variety breeding.
