摘　　要：对光温敏核不育水稻籼S进行了繁种研究,结果表明,在广州自然条件下其越冬繁殖产量为0.55 t/hm2,可以用于原原种生产、对不育系进行加代繁殖等;而在清远的冷繁产量可达2.19 t/hm2,基本能达到大面积生产的要求.A series of experiments on multiplication of XianS were conducted. The results showed that under natural conditions in Guangzhou, the yield over winter reached to 0.55 t/hm^2 and could be used as original seeds and adding-generation multiplication. The yields by cool multiplication could reach to 2.19 t/hm^2, which meets the requirement for large-area production.
