| Abstract: | The RAPD analysis was used to study the genetic diversity of three natural populations of pinctada martensii Dunker obtained from San Ya,Hai Nan Province(SY),Yang Pu Harbor,Hai Nan Province(YP),Wei Zhou island, Guang Xi Province(WZ) and a cultivated population obtained from Lei Zhou,Guang Dong Province(LZ).The random primer containing 20 nucleotide of M group made in Operom Company was used in this study.The genetic Similarity of each population were 0.586 6,0.651 4,0.666 6, 0.715 8 respectively.and the order from small to big was SY, YP,WZ, LZ. The genetic variability of each population were 0.413 4,0.348 6,0.333 4, 0.284 2 respectively and the order from big to small was SY, YP,WZ, LZ. We can find that the genetic diversity of natural population was more than cultivated population. |
