采用微卫星技术,用9对微卫星引物对4个鲫鱼群体普通鲫鱼(C.auratus auratus)、红鲫(C.auratus red var)、白鲫(C.auratus cuvieri)和彭泽鲫(C.auratus auratus var.Pengze)的遗传多样性及亲缘关系进行研究.结果表明,4种鲫鱼的平均遗传杂合度值在0.607～0.721,其中白鲫0.721、红鲫0.652、彭泽鲫0.629、鲫鱼0.607;平均多态信息含量值在0.530～0.670,其中白鲫0.670、红鲫0.586、彭泽鲫0.549、鲫鱼0.530.由此可见,4个鲫鱼群体的遗传多样性总体水平较高,但白鲫的遗传多样性最高,鲫鱼的遗传多样性最低.在4种鲫鱼群体间,鲫鱼和白鲫群体间的遗传相似性指数最小(0.714),遗传距离值最大(0.286),说明这两种...

The genetic diversity and the phylogenetic relationships of four breed varieties of C.auratus cuvieri,C.auratus red var,C.auratus auratus and C.auratus auratus var. Pengze were studied by using microsaterllite technology and nine pairs of microsatellite DNA primers. The results showed that the average heterozygosity of the four breed varieties of Carassius sp. ranged between 0.607 and 0.720, which was 0.720 for C.auratus cuvieri,0.650 for C.auratus red var., 0.630 for C.auratus auratus var.Pengze, and 0.610 for C.auratus auratu. The average polymorphism information contents ranged from 0.530 t...
