| 摘 要： | 通过７个探针、１７种内切酶探针组合对１１８份普通野生稻和７６份亚洲栽培稻的线粒体ＤＮＡ（ｍｔＤＮＡ）ＲＦＬＰ分析表明，籼粳分化是亚洲栽培稻线粒体基因组分化的主流，７６个栽培稻中，３６个品种ｍｔＤＮＡ为籼型，４０个品种ｍｔＤＮＡ为粳型。普通野生稻ｍｔＤＮＡ以籼型为主（８６份），粳型较少（７份），１份类型难以确定，还有２４份没有籼粳分化。

| Abstract: | Genetic differentiation of mitochondrial DNA (mtDNA) of 118 accessions of common wild rice ( O.rufipogon Griff.) varieties and 76 cultivated rice ( O.sativa L.) uarieties were studied by RFLP analysis using 7 probes from mitochondrial DNA of rice, wheat and pea. It was indicated that indica-japonica differentiation is the main trend in mtDNA of cultivated rice. In the 76 cultivars, mtDNA of 36 cultivars are indica-type, and mtDNA of 40 cultivars are japonica -type. For wild rice, mtDNA of 86 accessions is indica -type, 7 accessions are japonica -type and 24 accessions are wild rice type. |
