| 摘 要： | 1 INTRODUCTION Silver carp (Hypophthalmichthys molitrix) is an important species in freshwater fisheries and ranks the first in world fish production (Li, 1993). China has a long history of aquaculture of silver carp that is very difficult for selective breeding because it has a long life cycle. However, development of cytoge-netics and modern molecular genetics built up a strong impact to the research on selective breeding. A rapid, efficient approach for establishment of a pure line of…

| Abstract: | Three artificial gynogenetic clones of silver carp were produced for the analysis of restriction enzyme digestion patterns of ND5-ND6 region from mtDNA of the clones. It is revealed that all intraclonal individuals shared completely the same digestion patterns but among interclonal individuals did not. The three clones were mixed and cultured in a pond together for two years, and restriction endonuclease digestion patterns of ND5-ND6 were used as genetic markers to assess the growth performance of each clone. |
