Yellow pond turtle,Mauremys mutica and three-striped box turtle,Cuora trifasciata,is classified to Bataguridae,Mauremys and Cuora,respectively,they distribute in Southern China. The two turtles have been artificially-propagated successfully and were cultivated in a small-scale. Mauremys iversoni is a new strain nominated by Pritchard in 1991,but in 2001,two research groups leading by Parham and Wink proved that Mauremys iversoni was not a species. With different methods,they found that Mauremys iversoni may be the hybrid of yellow pond turtle and three-striped box turtle. In this article,the hybrid of M. mutica (♀) × C. trifasciata (♂) was acquired successfully,which indicated the hybrid between genus of Mauremys and Cuora was feasible. But the rate of fecundation and hatching of M. mutica (♀) × C. trifasciata (♂) were lower than M. mutica (♀) ×M. mutica (♂). The veins on carapace,the dark patch on plastron,the forepart form and origination of gular scute,the ratio between gular scute width and gular scute seam length,gular scute seam length and humeral scute seam length,femoral scute seam length and anal scute seam length,the skin color of inside of four limbs and tail abdomen of the young hybrid were different from the young M. mutica. The growth rate of the one year old hybrid was faster than M. mutica in the same culture condition. In morphology of hybrid,the color of calvarias was thin brown-yellow,and it has two black lines behind the eyes,the abdomen of neck was yellow; the carapace was brown and its plastron was thin yellow,each scute of plastron has radiated dark patch,the skin color of inside of four limbs and tail abdomen of the hybrid were yellow-brown. The analysis of morphologic data within three kinds of turtles indicated that the hybrid was more closed to its mother,M. mutica. Morphologic discriminant formula of three turtles were obtained,discriminant analysis indicated that there were significant different among three kinds turtles. The identification accuracy was 100%(p0.01). The ratio between second half plastron length,gular scute width,humeral scute seam length,femoral scute seam length,respectively,and carapace length were the highest contributing rate on discriminant analysis,which could be the direct parameter in distinguishing yellow pond turtle,three-striped box turtle and their hybrid. The study would be benefit to identification of hybrid,turtle breeding and aquaculture.
