摘　　要：考查三系不育系元丰A的遗传特性,结果表明:元丰A具有开花习性好、抗性强、米质优、配合力好等优点,其配制组合抽穗期遗传表现与博白A组合相似,抽穗期是否超亲(感光)取决于不同生育期类型的恢复系。配制弱感光杂交稻表现优势强、抗性好、米质优,可作为抗病、优质三系杂交稻选育的亲本。Genetic characteristics of CMS line Yuanfeng A rice were studied in preparation of breeding a low-photosensitive hybrid. The results showed that Yuanfeng A had the desirable flowering trait, disease resistance, grain quality and crossing ability. The genetic performances at the heading stage of the cross-combinations generated from it were similar to those from Bobai A. Whether the phenotype （photosensitivity） appears in their hybrid F1 at head-ng stage or not depended on the work of the restorer line at different growth periods. The resultant hybrid showed strong heterosis, improved resistance and excellent grain quality. Therefore, Yuanfeng A was believed to be a potential candidate for breeding high quality three-line hybrid rice.
