| 摘 要： | 为研究红莲型水稻细胞质雄性不育的分子基础，我们提取纯化了红莲型水稻丛广４１Ａ和丛广４１Ｂ的线粒体ＤＮＡ，采用限制性内切酶酶切片段长度多态性（ＲＦＬＰ）方法比较了红莲型不育系和保持系线粒体ＤＮＡ酶切图谱，发现两者之间存在一定的差异，部分支持了细胞质雄性不育与线粒体ＤＮＡ有关的结论。

| Abstract: | In order to study molecular mechanism of cytoplasmic male sterility (cms) HongLian cytoplasm in rice (Oryza sativa L.), the mtDNA were prepared from ChongGuan 41A,ChongGuan 41B.Copared comparison between mitochondral DNA of sterile line ChongGuan 41A with that of the maintainer ChongGuan 41B were detected polymorphism.This result partly supported the hypothesis that mitochondrial DNA probably is related with CMS. |

| Keywords: | HongLian rice cytoplasmic male-sterility restriction patterns of mitochondrial DNA |
