Key factors affecting the digestion-ligation,pre-amplification and selective amplification in amplified fragment length polymorphism（AFLP） analysis in sesame（Sesamum indicum L.） were optimized.Results showed that the best protocol was 200 ng/μL template DNA,digestion-ligation at 37 ℃ for 6 h,1.0 mmol/L Mg2＋,0.3 mmol/L dNTP,0.5 U Taq DNA polymerase in the pre-amplification system and pre-amplification products diluted by 10 times,1.0 mmol/L Mg2＋,0.2 mmol/L dNTP,and 1.0 U Taq DNA polymerase,0.6 mmol/L primers in the selective amplification.
