THE GENETIC DIVERSITY OF CULTURED MYTILUS CORUSCUS POPULATIONS BASED ON SEQUENCE ANALYSIS OF MITOCHONDRIAL COⅢ GENE
基于线粒体COⅢ基因分析厚壳贻贝(Mytilus coruscus)养殖群体遗传多样性

The genetic diversity and genetic structure of three cultured populations(Wenzhou of Zhejiang province,Ningde of Fujian province and Fuzhou of Fujian province) of Mytilus coruscus were determined using the mitochondrial gene sequencing technology(COⅢ).The result revealed 21 haplotypes for total 23 individuals obtained using PCR method.The haplotype diversities(Hd),nucleotide diversities(P i) and the average nucleotide differences(K) were 0.978,0.01045 and 8.534,respectively,which showed high genetic diversity among populations.The fixation indices(F st) of three populations showed that there was no genetic differentiation between Wenzhou and Ningde populations and some genetic differentiation between Fuzhou population and the other two populations.
