摘　　要： 对采自云南石屏和元江的虎纹蛙进行外部形态特征和染色体核型分析。结果表明:元江虎纹蛙体形、体质量均明显大于石屏,其中,后肢全长、胫长、鼓膜宽、头宽等指标差异显著;两地虎纹蛙核型均为2n=26(5L+8M+0s),NF=52;石屏虎纹蛙的第3号为亚中部着丝点染色体(SM),其余为中部着丝点染色体(M),次缢痕位于6 p;元江虎纹蛙第36、和8号为SM染色体,其余为M染色体,在3 p和6 p上具有不明显的次缢痕;显示不同地区虎纹蛙形态和核型均存在差异,推测石屏和元江产虎纹蛙可能是同种中的不同地理居群。 The morphological characters and karyotype of Rana tigrian rugulosa were analyzed using samples from Shiping and Yuanjiang of Yunnan.The results demonstrate that Rana tigrian rugulosa from Yuanjiang was bigger and got more weight than Shiping ones.Morphological characters such as length of hind limb,length of tibia,eardrum width and head width were significantly different between Yuanjiang and Shiping ones.Samples from different locations enjoyed the same karyotype： 2n=26（5L＋8M＋0s）,NF=52.The chromosome No.3 of Rana tigrian rugulosa from Shiping was SM,while the rest chromosomes were M,and the secondary constriction located on 6p.The chromosome No.3,6 and 8 from Yunjiang were SM,the rest were M,and the unobvious secondary constriction located on 3p and 6p.It was significant different at morphological characters and karyotype between Yuanjiang and Shiping samples.Yuanjiang and Shiping samples might be speculated as the geographical groups of Rana tigrian rugulosa.
