摘要：

Genetic homogeneity between Pengze crucian carp and strain A of silver crucian carp was studied by using transferrin, isozyme and RAPD markers. The studied individuals of Pengze crucian carp showed transferring patterns were the same of silver crucian carp A strain while distinct from those of other crucian carp populations. As far as isozyme is concerned, the MDH, LDH and EST are all of the same with only slight differences in SOD between them. The RPAD patterns clearly indicated high homogeneity among 16 individuals(6 sampled from individuals of two years old and the others aged one) from crucian carp of Pengze and 5 individuals from strain A of silver crucain carp. Nearly indentical banding patterns were observed among all individuals. Average genetic distance within all the individuals is only 0.011, suggesting crucian carp of Pengze might possess indentical genetic background with strain A of silver crucian carp.
