摘　　要：为改良丰39S的稻瘟病抗性,以具有广谱抗性基因Pi9的抗源材料75-1-127为供体、丰39S为受体,通过杂交、回交和自交,并利用分子标记辅助选择方法,育成了籼型水稻光温敏核不育系安农086S。结果显示,安农086S具有理想的株叶形态以外,还具有适当的播始历期、较好的开花习性及异交结实性等特点。田间自然温光特性鉴定和人工气候室温光特性鉴定结果表明,安农086S的不育性稳定、不育时期较长。稻瘟病抗性鉴定结果显示,安农086S抗稻瘟病强。此外安农086S的稻米品质优、配合力强、繁殖技术简单易行。In order to improve the resistance of Feng 39s to blast disease,we developed Indica rice photo-thermo sensitive nuclear sterile line Annong 086S with feng39s as the acceptor and 75-1-127 as the donor with broad spectrum blast-resistance gene Pi9 by hybridization,backcross and self-crossing and molecular marker-assisted selection.The results showed that Annong 086S not only had the ideal plant and leaf morphology,but also had the characteristics of appropriate period of sowing to initial heading,good flowering habit and good out-cross fecundity.The results of field natural and artificial climate chamber photo-thermo sensitive characterization showed that the sterility of Annong 086S was stable and the sterility period was long enough.Rice blast resistance identification results showed that Annong 086S had high resistance to rice blast.In addition,Anong 086S rice showed excellent quality,strong combining ability and simple reproduction technology.
