In this study，pepper hybrid cultivars Ganke 4、Ganke 10 and their parental inbred lines were used to identify hybrid purity by SSR markers， aiming at establishing a quick and efficient purity identification system for tested varieties， verifying the published pepper SSR core primers at the same time. The results showed that there was one primer pair selected in each cultivars，named Es330 and Epms923， which had significant difference between the parental inbred lines， and showed co-dominance in the hybrids. Using the two primer pairs to identify the purity of the tested varieties，the purity of Ganke 4 was 96.4%， which had 1.8 percentage point difference from the purity of 98.2% identified in field. the purity of Ganke 10 was 91.8%，which had 0.9 percentage point difference from the purity of 92.7% by field identification. It was proved that the identification of hybrid purity of Ganke 4 and Ganke 10 were authentic and reliable， the two SSR markers could be used for efficient and rapid identification of hybrid purity.
