Abstract

Abstract

Genetic variation of three wild stocks of Meretrix meretrix was analysed using random amplified polymorphic DNA(RAPD)markers,50 primers got amplified bands in total of 60 primers,amplified bands of 15 primers were selected as statistic similarity index and genetic distances.Genetic distances of intra stock of Liaonin,Jiangsu Province and the Zhuang Autonomous Region of Guangxi are 0.169±0.034,0.117±0.032 and 0.108±0.031,respectively;and those of inter stock of Liaonin-Jiangsu,Jiangsu-Guangxi and Guangxi-Liaonin are 0.222± 0.036,0.209±0.013 and 0.316±0.047,respectively,the results show that genetic distances of three stock in crease with distance increase.The marker of s396-900 bp is owned by Jiangsu and Liaonin stocks,and marker of s433-250 bp is owned by Jiangsu and Guangxi stocks,three stocks were indentified by this two markers.
