摘　　要：利用RAPD技术分析了小麦耐盐突变体RH8706 49、其母本濮农3665以及与49同为"一粒传"后代的敏盐材料H8706 34的线粒体DNA,发现三个材料的线粒体DNA存在有明显的差异,初步认为这些差异可能与突变体49耐盐性的增强相关,回收克隆了突变体49线粒体DNA的特异扩增产物,为进一步的研究打下了基础。The mtDNA of wheat salttolerant mutant RH870649,its female parentPunong 3665 and saltsensitive material H870634 were studied by RAPD.There are differences among the three materials.It suggested that the differece might be related to the increase the salttolerance of the mutant 49. The special amplified products of mutant 49 mtDNA were cloned.
