水稻雄性不育系育种研究进展与应用OA

Studies of rice male sterile lines has made a significant contribution to the utilization of heterosis and significantly improved the yield,grain quality,and resistance of rice.Analyzing the molecular mechanisms of male sterility and fertility restoration in rice is of great value to modern agricultural production and can provide a reference for the innovation of hybrid rice breeding technology.This paper reviewed the research progress in fertility regulation mechanisms of cytoplasmic male sterility(CMS),environment-sensitive genic male sterility(EGMS),and spontaneous genic male sterility(SGMS)in rice.Furthermore,this paper systematically summarized the germplasm resource creation methods such as natural mutation,mutagenesis breeding,hybrid breeding,molecular marker-assisted breeding,and gene editing breeding.Finally,this paper clarified the current situation,analyzed existing problems,and proposed future development directions of the breeding and application of male sterile lines in rice.
