| Abstract: | Based on SSR markers developed for the whole pepper genome,the genetic diversity of 26 major pepper cultivars grown in Qinghai were analyzed in current study,and their molecular fingerprints were constructed.The results showed that 6 pairs of primers with stable amplification and good polymorphism were selected from 117 pairs of SSR markers,and a total of 36 gene loci were amplified from 6 pairs of markers,with a polymorphism ratio of 97%.The genetic similarity coefficient among 26 pepper varieties was 0.37-1.00,and the 26 pepper materials could be grouped into 4 types at GS 0.5. Preferably,the four pairs of primers (pepperSSR01,pepperSSR04,pepperSSR06 and pepperSSR08) could distinguish the tested pepper materials accurately and quickly. |
