Characteristics of twenty SSR loci used in the present study detected by Popgene software.

NB, NA, NE, NPA, PPA, NSA, PSA, PIC, I, H and DP represent the observed number of bands, the observed number of alleles, the mean value of effective alleles, the number of polymorphic alleles, the proportion of polymorphic alleles (%), the number of specific alleles, the proportion of specific alleles (%), the polymorphism information content, the mean Shannon's information index, the mean Nei's gene diversity index, and the discriminating power, respectively.
