Abstract: The development course about mechanization of seed production of hybrid rice at home and abroad were reviewed and analyzed in this paper. It was proposed that hybrid rice seed production technology in China could be divided into three development phases: the phase of experience to try to find out and to accumulate about the hybrid rice seed production technology (1973-1980), the phase of technical enhancement and technical consummation (1981-1990), and the phase of the research, adoption and application (1991-until now) .The adoption and application of hybrid rice with big area and hybrid rice seed production technology have been also in advance. It was thought that the seed production mechanization technology in hybrid rice must be improved from now to raise its seed quality and the benefit of seed production and the competitive power of seed production technology in China. The seed production mechanization technology in hybrid rice in the weed killer sensitive gene to induct the male parent law, the anti-weed killer gene to induct the female parent law and the method of rice husk color code hybrid rice mixes planting has been carried out until now. The mixes planting seed production mechanization technology of hybrid rice has been obtained success application in small area, other methods also are experimenting and researching. Therefore, the seed production mechanization technology in hybrid rice must be promoted by the rice breeders and the farm machinery experts throughout cooperation closely from now.
