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.
