Abstract:

The current survey of genetic structure and genetic diversity of grass carp in the water of three rivers, the Yangtze River, the wild population and cultured population were reviewed in this paper. At last, the prospect in these ways was described in this paper. The following conclusions were reached: the genetic diversity of grass carp is lower and wild populations is higher than the breeding populations in genetic diversity. As a result, Filtering the marker locuses of higher genetic diversity by different molecular markers which could be useful for grass carp molecular breeding.
