| Abstract: | Objective] The aim was to optimize the SSR-PCR non-denatured polyacrylamide gel electrophoresis conditions in kernelled apricot.Method]25 accessions of kernelled apricot and three accessions of edible apricot were selected as experimental materials to screen the repeatable SSR loci with high polymorphism by the use of SSR markers combined with non-denatured polyacrylamide gel electrophoresis.And the effect of different factors on electrophoresis conditions was compared to explore the optimal SSR-PCR non-denatured polyacrylamide gel electrophoresis conditions in kernelled apricot.Result]The optimal non-denatured polyacrylamide gel electrophoresis conditions for SSR-PCR were established as follows：polyacrylamide gel concentration 6%,the ratio of acrylamide to bisacrylamide 29∶1,electrophoresis at 1 000 V for 2-3 h,and staining for 15 min within 0.1% AgNO3.Conclusion]The optimum electrophoresis system has provided some technical foundations to further study the phylogenetic relationship of kernelled apricots by SSR markers. |
