Based on the wild base-populations sampled from Hunan and Jiangsu provinces, six breeding populations of , including four pedigree-bred and two population-bred populations, were cultured. The growth properties of four pedigree-bred populations were studied and the genetic characteristics of all six breeding populations were analyzed with seven microsatellite DNA markers. The growth speed of the pure-bred families were significantly higher than geographic hybrid families, but there was no direct relationship between the growth rates and heterozygosities. The number of private alleles of the pedigree-bred populations was about 29.33% more than that of the two population-bred populations. This means that the establishment of family with different geographic populations might raise the level of genetic diversity. The genetic differentiation within breeding populations was significant (=0.4388). The relative farther genetic distance between the pure-bred populations and the pedigree-bred populations revealed that the hybridization between them might obtain some offsprings which exhibited heterosis. Private allele G14₄₃₇ could be used as the specific molecular markers for JCJC population, while G5₅₃₀ used to distinguish the geographic hybrid populations (HCJC and JCHC) from other breeding populations.
