水稻光敏感核不育系在长日下不育、短日下可育。光敏核不育基因从粳稻转育到籼稻后,其不育特性是可以遗传的。W6154s 是湖北省农科院选育、经“863”专家组鉴定并认可的优良核不育材料。广东引种后对其育性转换和全不育期的表现尚未见报道。我们对 The rice light-sensitive nuclear sterile lines are sterile in long days and fertile in short days. Photosensitive genic male sterile gene from japonica rice to indica rice, its sterile characteristics can be inherited. W6154s Hubei Academy of Agricultural Sciences breeding, the “863” expert group identified and approved fine nuclear sterile materials. After the introduction of Guangdong, its fertility transformation and all-sterile period have not been reported. We
