| Abstract: | Obtaining the stable and repeatable ISSR-PCR amplification result is the basic work to study genetic diversity of Castanopsis eyrei .The ISSR-PCR amplification system was optimized by using orthogonal design in six factors and five levels (Mg2 + , dNTP , primer , Taq DNA polymerase , bovine serum albumin and template DNA).The suitable reaction conditions of ISSR-PCR were shown as follows :1 Taq buffer (10 mmolL-1 Tris-HCl , pH 9.0 , 50 mmolL-1 KCl , 10 gL-1 TritonX-100), 1.7 mmolL-1 Mg 2+ , 0.25 mmolL-1 dNTP , 8.34 nkat Taq DNA polymerase , 1.5 gL-1 bovine serum albumin , 6 pmol primer , 12 ng template DNA in 10 L reaction volume .The optimal annealing temperature for primer UBC 846 was 56.3 ℃.
