Abstract: In order to investigate the germplasm genetic diversity and genetic relationship of ornamental pomegranate (Punica granatum L.), the genetic relationships of 35 ornamental pomegranate cultivars were evaluated by ISSR markers. Eight ISSR primers with good polymorphism were screened out. A total of 168 bands were amplified from 8 ISSR primers, of which 158 bands were polymorphic loci. The percentage of polymorphic band (PPB) was 94.05%, the number of alleles (Na) was 1.940 5, the effective number of alleles (Ne) was 1.678 5, Nei's gene diversity (He) was 0.379 9 and Shannon's information index (I) was 0.553 0. The genetic similarities coefficient (GS) between cultivars ranged from 0.416 7 to 0.922 6, suggesting ornamental pomegranate cultivars had abundant genetic diversity. Thirty-five ornamental pomegranate cultivars were divided into 6 groups at GS of 0.668 based on UPGMA method.
