In my experimentⅠcompare the purposes of different combinations of endoenzyme(MseⅠ-HindⅢ, MseⅠ-PstⅠ, MseⅠ-EcoRⅠ) and find that MseⅠ-HindⅢeasily finds thepolymorphism by primers combinations suiTab for AFLP analysis.And by means of this there aremany polymorphism strips. So the double endoenzyme of AFLP was exercisedfor the analysis of soybean cytoplasmic male sterility.In the cource of my experiment, 64 primerpairs of MseⅠand HindⅢwere exerted to analyse the twe mtDNA pools which are made ofsterilities and holdings and the polymorphisms of sterilities and holdings.

运用扩增片段长度多态性的方法，对独特的杂交大豆试材进行分析研究，通过比较MseⅠ-HindⅢ、MseⅠ-PstⅠ、MseⅠ-EcoRⅠ不同酶切组合的效果，结果表明MseⅠ-HindⅢ较容易找到多态性引物组合，而且具有较高的多态性，本试验选用MseⅠ-HindⅢ进行双酶切大豆线粒体DNA从而完成AFLP的分析工作，试验用64对MseⅠ和HindⅢ引物对两个不育系及保持系材料的线粒体DNA制成的pool进行AFLP标记分析，分析了不育系与保持系之间的多态性； 4。
