摘 要: | Genetic diversity of three cultured populations of jade perch (Scortum bacoo) are studied using amplified fragment length polymorphism (AFLP) markers, which is Guangzhou(GZ) population, Foshan (FS) population and Qingdao(QD) population. Nine primer combinations were used and 385 fragments were detected. Among the 385 fragments, 80 bands (20.78%) were polymorphic. And it can be speculated that the genetic diversity of the three cultured populations of jade perch was very poor according to the gene genetic diversity among populations (Ht), the gene genetic diversity within populations (Hs) and Shannon-Weiner index (I). From gene differentiation (Gst), genetic distance (D), genetic similarity (5), and UPGMA analysis, it is found that the relationship among the three populations is very closed, and the difference in genetic diversity among the three populations is not significant. Further clustering relationships of the jade perch cultured populations also are correlated to historical-breeding observations and genetic relationships. The GZ population clustered together with the QD population first, then with FS population.
