Abstract:To enrich the molecular marker method for willow trees,an improved reaction system from a sequence-related amplified polymorphism-polymerase chain reaction (SRAP-PCR) of Salix matsudana(Hankow willow) was obtained with an orthogonal design.In addition,the temperatures for two annealing methods were optimized in the PCR amplifier and a polyacrylamide gel electrophoresis (PAGE) was employed.Results showed that the reaction system was 20.84 nkat Taq,2.00 μL Mg2+(25.00 mmol·L-1),2.50 μL deoxyribonucleotide triphosphates (dNTPs)(2.50 mmol·L-1 each),1.50 μL primer(20.00 μmol·L-1),100.00 ng template,and 2.50 μL 10 × Taq buffer in 25.00 μL.The program was as follows:94 ℃ for 2.0 min;then,for 5 cycles,94 ℃ for 1.0 min,38 ℃ for 1.0 min,and 72 ℃ for 1.5 min;next,at 30 cycles,94 ℃ for 1.0 min,54 ℃ for 1.0 min,and 72 ℃ for 1.5 min;and finally 72 ℃ for 10.0 min.Results of PAGE showed that clarity and amount of information increased with the new procedure.Thus,this superior method could be used for research on S.matsudana.
Keywords:forest tree breeding  Salix matsudana  SRAP  orthogonal design
