Abstract: S genotypes of 30 apricot cultivars native to China were detected usingS-allele-specific PCR with 5 pairs of Prunus consensus primer combinations which had been published, and amplification effects were evaluated according to coefficient and efficiency of amplification. The results were as follows: ①The effects of PCR amplification with 5 primer combinations were different greatly. The primer combination EM-PC2consFD+EM-PC3consRD was the most suitable for Chinese apricot, and its’ coefficient and efficiency of amplification were 66.7% and 53.3%, respectively; ②No amplification was obtained using the combination EM-PC2consFD+EM-PC3consRD in the two cultivars ‘Huaxian Dajiexing’ and ‘Zhupi Shuixing’ while the other two combinations, PruC2+PruC4R and PaConsⅡ-F+PaConsⅡ-R, could amplify two fragments: In addition, no amplification was obtained using all the five pairs of combinations in the two cultivars ‘Lanzhou Dajiexing’ and ‘Baimuxing’. Then it could be concluded that, to detect S genotypes of all Chinese apricot cultivars accurately, new specific primers need to be developed besides the five primer combinations; ③The results amplified in the four cultivars ‘Hongfeng’,‘Xinshiji’, ‘Honghebao’ and ‘Erhuacao’ by two pairs of combinations, EM-PC2consFD+EM-PC3consRD and PruC2+PruC4R, showed that it was of validity to evaluate amplification effects of different primer combinations according to coefficient and efficiency of amplification in this study.
