The invention provides a male parent staged sowing method for summer radish hybrid seed production. In the method, male parents are sown at threes stages after female parents are sown, the sowing time of the first stage of the male parents is 75-95 days after the female parents are sown, the sowing time of the second stage of the male parents is 50-70 days after the first stage of sowing of the male parents, and the sowing time of the third stage of the male parents is 10-29 days after the second stage of sowing of the male parents. The male parents are sown at three stages after the female parents are sown, and therefore the florescence of male parent plants is prolonged to about 60 days from the existing about 20 days, and it is just ensured that the florescence of the male parents completely covers that of the female parents; the number of the male parent plants is increased by 1.5 times or above after the three stages of sowing; the pollen quantity is sufficient, sufficient pollen is supplied to female parent plants to the maximum extent, the pollination time of the female parent plants is prolonged, and the setting percentage is increased. The florescence of the male parents and that of the female parents completely overlap, and the seed production yield is improved by one time or above compared with that of the single stage of sowing of the male parents.
