摘　　要：对国内外超级稻(超高产)育种研究作了回顾,简述了广东省超级稻育种研究取得的进展:育成了10个达到(基本达到)超级稻(准超级稻)产量指标的新品种(组合),并逐步进入生产示范和推广;初步创立了华南超级稻"半矮秆、早长根深"育种模式和华南双季超级稻"动态株型结构"育种模式两种理论。提出广东省今后超级稻育种与应用研究的课题是:提高超级稻品质和综合抗性;加强超高产栽培技术的研究和推广;改进超级稻品种(组合)区域试验的方法,加快超级稻推广。The history and progress in super-rice breeding or super high-yield production both in China and abroad were briefly reviewed in this paper. Ten super-rice or super-rice-like varieties (combinations) matching the super-rice or super-rice-like criteria have been bred and released for demonstration and extension. Two theoretical models, namely, 'semi-dwarf, early growth and deep root' model for super-rice and 'dynamic plant type' model for double-season super-rice, for South China have been established preliminarily. Further efforts on super-rice breeding and relating work in Guangdong province should aim to: improving grain quality and comprehensive tolerance; strengthening research and extension of cultivation techniques for super high-yielding; improving the methodology for regional trials of super-rice varieties (combinations); and enhancing the extension of super-rcie. 
