The resuhs indicated that the optimal concentrations of various components in a 20 ill ISSR-PCR reaction system of S. przewalskii Maxim. were ： 2 ul of 10 x buffer （ Mg2＋）, 0.4 mmol/L dNTPs, 1.0 U of Taq DNA polymerase, 0.3 umol/L ISSR primers and 30 ng of DNA template. This study laid the foun- dation for the utilization of S. przewalskii Maxim. germplasm resources.展开更多
