摘要
利用常现杂交有种结合花药培养技术，筛选出具有广亲和特性的模型光敏核不育系H52S，其育性转换明显，不育期内不育株率与不有度均达100％，可育期内自然结实率达40％以上；将其与广亲和测试种杂交，F1结实率达80％以上，经初步亚种间配组分析，显示强大的增产潜力．
Wide Comatibility Photoperiod Sensitivc Genic Male Sterile Rice H52S was obtained with cross technique and anther culture.It's fertility changes obviously and the raio of sterile plants and the sterility are all 100% at the sterile stage,the fertility is over 40% at fertle stage.The F1 Fertility of crosses between H52S and the test vdrieties of wide compatibility is over 80%. The hybrids between H52S and serval indica rice showed high yield potental.
