摘　　要：我国育种家在20世纪40年代中期提出通过雄性不育利用水稻杂种优势的技术构想,在70年代中期最先实现水稻杂种优势生产利用。我国水稻杂种优势利用技术是在杂交试验过程中提出并逐渐完善的,它的早期探索大致经历了40年代提出技术构想、50年代积累物质和认识基础、60年代试验探索三个阶段。Chinese breeders came up with the idea of male sterility application of Rice Hetero- sis utilization technology in mid 1940s, and the Rice Heterosis utilization technology was firstly ap- plied and produced in 1970s. The Rice Heterosis utilization technology in China has been construc- ted and improved in cross tests during three earlyexplorations, from technical conception in 1940s, material and knowledge base building in 1950s and experimental researches in 1960s.
