Abstract:

To analysis the chromosome number and karyotype of Leptobotia taeniops. The karyotype of Leptobotia taeniops was studied through the chromosome preparations obtained from head kidney by the method of injecting PHA and colchicines and used air drying method to make chromosome samples. The total chromosome number of the fish was 50, the karyotype formula was 2n=6m+10sm+8st+26t, and NF=66. There was no visible evidence of po1yploidy chromosome and sex chromosome. This study provided Leptobotia taeniops with cytogenetics paramete, and offered a theoretical basis for Cross breeding of Leptobotia taeniops.
