Research and Application of the Third-Generation Hybrid Rice
This study introduces the research progress and exploration process of the third-generation hybrid rice breeding using common nuclear male sterile line as genetic tool,and expounds the technical characteristics and ap-plication value of the third generation hybrid rice.Ever since the advent of the third-generation hybrid rice sterile line Gt1s and its breeding line Gt1S in 2015,which marks one of its first successful adoptions in rice,third-genera-tion hybrid rice has seen breakthroughs in both theoretical advances and practical applications.Using this system,a batch of ideal third-generation hybrid rice sterile lines such as G3s,restorer lines such as R17-1,and premier hy-brid combinations such as'Sanyou1'with excellent performance and high yield have been developed and cultivated through the use of heterosis between indica and japonica subspecies.The research shows that the establishment of the third-generation hybrid rice system and its successful application will expand the current landscape of rice ge-netic modification techniques,and revolutionize rice breeding and production.
