| 摘 要： | 选用分布于水稻12条染色体上与抗稻瘟病基因紧密连锁的86对SSR引物,对30份稻瘟病抗性水稻材料进行遗传多样性分析.结果表明,19对引物在30份材料间表现出多态性.UPGMA聚类分析结果表明,供试材料可分为6类,反映出供试材料抗性遗传相似度低,遗传背景差异较大.聚类结果与材料的田间抗性表现基本一致,遗传亲缘关系基本吻合...

| Abstract: | Total 86 SSR primers located at 12 chromosomes in rice,which were closely linked with blast resistance genes,were selected to analyze the genetic diversity of 30 blast resistant rice materials.The results indicated that 19 SSR markers performed polymorphism in the 30 materials.The results of cluster analysis by UPGMA method showed that 30 materials could be clustered into six groups which reflected that those tested materials had low similarity in resistance inheritance and large variation in genetic backgr... |
