赣江中游四大家鱼遗传多样性的ISSR分析

利用ISSR分子标记技术对赣江中游四大家鱼的遗传多样性进行分析,青鱼（Mylopharyngodon piceus）、草鱼（Ctenopharyngodon idellus）、鲢（Hypophthalmichthys molitrix）、鳙（Aristichthys nobilis）分别扩增出47、74、55、59个位...

Study of Four Major Chinese Carps with Inter Simple Sequence Repeat（ISSR） Markers in the Middle Reach of Ganjiang River

The colonial genetic variations in four major chinese carps were analyzed with ISSR, which generated 47 （ black carp） , 74 （ grass carp） , 55 （ silver carp） and 59 （ bighead carp） bands. The number of polymorphie band were 33,50, 29, 30, and the pecerentage of polmoryphism were 70.21%, 67.57%, 52.73%, 51.72%. The index of Nei＇s gene diversity and Genetic diversity quantified by Shannon Index varied of black carp were 0. 2606 and 0. 3846, grass carp were 0. 2391 and 0. 3560, silver carp were 0. 1858 and 0. 2769, bighead carp were 0. 1908 and 0. 2827. The experiment results showed the heredity and variation space was a little larger in the four major Chinese carps in Xiajiaug reach of Ganjiang River, their colonial genetic diversity were abundant.
