Effect of different female/male ratios on hatching rate of Pelodiscus sinensis in artificial propagation.

Under the same hatching condition,the hatching rate of the fertilized eggs from different ratios of Pelodiscus sinensis parents had no significant difference(P0.05) when the ratio of female to male was(5~8)∶1.The hatching rate had intimate connection only with the hatching environmental factors,and had nothing to do with sex ratio.
