RAPD analysis of genetic diversity of wild and cultured Hyriopsis cumingii
Wen HaiBo · JOURNAL OF FISHERIES OF CHINA · 2003
The genetic diversity of wild and cultured Hyriopsis cumingii was analysed using the random amplified polymorphism DNA(RAPD) technique. 20 random primers were sieved from 150 random primers, which could amplify 1 to 10 fragments individually with the fragment length varying from 500 to 2 000 bp. The intra-population genetic similarity of wild and cultured Hyriopsis cumingii is 0.787 and 0.833, respectively. It shows that gene variability in wild population is greater than that in cultured population. The inter-population genetic distance between wild and cultured Hyriopsis cumingii is 0.054. This means two populations of wild and cultured Hyriopsis cumingii have close relationship.
