Abstract: Establishing a rapid and stable seed purity identification technology system is the effective measure for controlling the pepper hybrid quality. The development of molecular marker techniques could provide an accurate and fast way for identifying the crops hybrid purity. In this study,SSR markers were applied to testing the purity of Rela No. 3. 10 pairs among 85 pairs of SSR primers showed significant polymorphisms between the parents of Rela No. 3. All of them were co-dominant markers. In order to improve the accuracy of identification results,three codominant SSR markers located on different chromosomes were selected for purity test of Rela No. 3. The seed purity was 99. 49%. Comparative analysis showed that the identification results of molecular markers and phenotypes were highly consistent. The study results indicated that SSR markers could be used for hybrid purity test of Rela No. 3, quickly and accurately.
