Pinctata martensi is one of the most important seashells in the southeast of China. In order to improve our understanding of this species and the efficiency of breeding by marker\|assisted selection, we used 20 primers to test different populations with the RAPD technique. We randomly collected wild individuals in Sanya (SS), Hainan Province and Beihai (BB), Guangxi Province. We allowed both intra and inter\|population mating (SS\-♀×BB\-\{♂\}→BS) among these individuals, getting three filial populations known as SS,BB and SB. Among the 20 primers, 14 produced highly reproducible profiles and generated 124 bands among the three filial populations. The genetic diversity index of the three populations (SS, BB and SB) was 0 247, 0 237 and 0 261 respectively. Genetic similarity between the two populations (SS with BB, SS with SB, BB with SB) was 87 24%,80 39%,83 90%. Finally, we analyzed the feasibility of interbreeding individuals from these two different areas.
