H_O, observed heterozygosity; H_E, expected heterozygosity; H_S, gene diversity; N_a, mean numbers of alleles; Ar, allelic richness based on eight samples per population; MLGs, number of multilocus genotypes; #within, number of MLGs shared within a population; #among, number of MLGs shared among populations; K, index of global genotypic diversity (MLGs /N); F_IS, the inbreeding index. The seven populations were named by their sampling locations, Beijing, Hubei, Hebei, Henan, Jiangsu, Shandong, and Shanxi, respectively.
