| 摘 要： | 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。

| Abstract: | The fertility appearance and utilizable value for PGML of rice in Hebei province were investigated. The experimental results were: The fertility appearance of PGML 1647s,31116s,E5047s and ABoo5s was stable in sterility and obvious in fertility alteration,therefore they can be used.Many fine two-line hybrid rice combinations were made by crossing PGML with japonica varieties.Their seed-setting rates in F1 was normal,growth duration was suitable,plant height was medium and heterosis was marked.Their yield competitive heterosis was over 20%. |

| Keywords: | photoperiod-sensitive genie male sterile line(PGML)of rice fertility alteration two-line hybrid rice heterosis. |
