The invention discloses pelodiscus sinensis sex identification specific primers and a method. The two pairs of primers in a sex identification primer system are a pair of female specific primers and apair of positive reference primers which can be amplified by using male and female genomic DNA. Among the primers, the female specific primers can only stably amplify a 196 bp band in the female genomic DNA, and the band cannot be amplified in the male genomic DNA; the positive reference primers can amplify a 482 bp band in the male and female genomic DNA. Thus, in a PCR reaction system, the female genomic DNA can amplify two bands of 196 bp and 482 bp, while the male can only amplify a band of 482 bp.
