Then, based on the optimal ISSRPCR amplification system, the concentration of DNA template and annealing temperature were selected. As a result, the optimal PCR (20 μL) mixture contained 1.50 mmol·L-1 Mg2+, 0.125 mmol·L-1 dNTP, 2.00 μmol·L-1 primer, 0.50 U Taq DNA polymerase, 2.5 μL 10×buffer and 40ng template DNA. The suitable annealing temperature of primer UBC891 was 54.2℃. With the optimal system of ISSR-PCR reaction, clear and steady bands were obtained in different individuals of Qingza No.3 and its male parent. The establishment of ISSR-PCR system could favor the studies on the purity and genuineness of hybrid rapeseed varieties by using molecular marker techniques. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2010.05.010
