| 摘 要： | 对棉花DNA提取程序和SSR反应体系进行了研究。利用正交设计对模板DNA、引物、Taq酶和Mg^2＋浓度4种成分以3个梯度进行优化和选择，结果表明，最优反应体系为15μL，其中含有：10×Taq buffer 1．5μL、Mg^2＋（25mmol／μL）1．5肛L、dNTPs（25mmol／μL）2．0μL、引物（20pmol／μL）各2．0μL、Taq酶（2．0U／μL）0．15μL、DNA模板（25ng）3．0μL、ddH2O补至15μL。采用建立的反应体系，利用8对引物对3个品种进行扩增，6％的变性聚丙烯酰氨凝胶电泳检测结果显示该体系扩增结果清晰稳定。 |

| Abstract: | In this paper the DNA extraction procedure of cotton and the SSR-PCR reaction system were optimized. Using orthogonal design, four factors including template DNA, primer, Taq polymerase,Mg^2＋ at three grads levels were optimized and selected to establish SSR reaction system for cotton molecular breeding. The results indicated that the optimal reaction system were 15 μL. including 10×buffer 1.5μL, Mg^2＋ （25 mmol/μL）l. 5 μL,dNTPs（25 mmol/μL）2.0 μL,Primer （20 pmol/μL）2.0μL for each one, Taq （2.0 U/μL）0.15 /μL,DNA（25 ng）3.0 /μL,ddH2O 2.85 μL. On optimal conditions,9 pairs of primers were used to analyze 3 eultivars of cotton; PCR products were tested by electrophoresis, using 6% denatured polyacrylamide gels. The results showed this optimal system was stable and reliable. |
