Abstract: In this paper,RFLP analysis was conducted in ribosomal DNA internal transcribed spacers (ITS) of Arca subcrenataArca inflata and Arca (anadara) granosa. The results showed that A. granosaa and A. subcrenata could be differentiated using restrictive enzymes of HaeⅢ,HhaⅠ,HpaⅡ,RsaⅠ,Sse9Ⅰand TaqⅠ,as well as A. granosaa and A. inflata. No specific RFLP marker was observed between A. subcrenata and A. inflata. Pnet value between A. subcrenata and A. inflata was zero,while Pnet values between A. granosa and the other two species were both 0.079 7. It was observed that there were 5 composite haplotypes in A. granosa and the nucleotide diversity index (π value) was 0.000 8,while one haplotype was observed in A. subcrenata and A. inflata and π values were both zero in these two species.

Key words: Arca subcrenata, Arca inflata, Arca (anadara) granosa, ITS, RFLP
