摘　　要：在秋季自然条件下对４个光温敏核不育水稻进行割茬再生繁殖。结果表明，割茬再生对培矮６４Ｓ、ＣＩＳ２８一１０和ＣＩＳ２８一１２２的自交繁殖有明显的促进作用，但对安农Ｓ一１的作用不明显。The studies on the ratooning reproduction of four photo一thermo一sensitivc genic male ster-ile rice(PTGMSR)lines were conducted after stem cutting in autumn. The experimental results showedthat the cutting method significaiitly increased both the pollen fertility and the spikelet fertilty of pei’ai 64S,GIS28一10 and GIS28一122,but did not distinctly influence thosc of Annong S一1.
