选取36个栽培稻、普通野生稻骨干系进行了RFLP聚类,并对分子标记法、程氏指数法和杂交亲和力法进行了比较分类.结果表明,三种分类方法对水稻材料的分类是基本一致的.采用不同方法进行整理分类,有利于对水稻材料的深刻理解与认识.通过RFLP聚类树状图、籼粳倾向性图及基因型的综合分析,明确了中国普通野生稻可分偏粳型和原始普野型,国外普通野生稻包括偏籼型与原始普野型.中国原始普野型相对倾粳,国外原始普野型相对倾籼,它们是遗传分化显著不同的两种类型.“,”RFLP clusters were made in selected rice elite lines including 36 cultivated and common wild rice.Also,comparison and classification were carried on among the three:molecular marker method,morphological character index method and cross compatibility method.The results showed that the classification was basicly the same and that it is beneficial to understand and recognize the rice material profoundly when arranging and classifying the rice material by three different ways.According to synthetic analysis of...
