通过对水稻光敏核不育系在河北省的育性表现及其利用价值的研究。证明：１６４７Ｓ等４个光敏核不育系的育性稳定且育性转换期明显，可以直接利用；用光敏核不育系为母本与当地粳稻良种配制的两系杂交稻组合Ｆ１的结实率正常，生育期适宜，株高适中，杂种优势大，产量高，其竞争优势一般为２０％以上，具有广阔的应用前景。
Fertility and Utilization of Photosensitive Genic Male Sterile Lines in Hebei Province. It is proved that the four photosensitive genic male sterile lines such as 1647S are stable in fertility and fertile transformation period and can be used directly. The seed set rate of F1 in two-line hybrid rice with photo-sensitive genic male sterile lines as female parent and local japonica hybrids Normal, suitable growth period, moderate plant height, heterosis, high yield, the competitive advantage is generally more than 20%, has broad application prospects.
