中国5个矮马品种的瓶颈效应分析

Abstract

Abstract: Thirteen microsatellite loci were used to analyze genetic equilibrium of five pony populations in China (Debao, Guizhou, Ningqiang, Sichuan, Yunnan). According to the allele frequency,under IAM, TPM and SMM three models, the sign test and Wilcoxon sign-rank test were used to analyze bottleneck of five pony populations. The results showed that Debao and Yunnan pony were observed in the significant level under IAM and Wilcoxon sign-rank test(P<0.05), Ningqiang pony was observed in the significant level under SMM and sign test(P<0.05), but no one population in the significant level under TPM model(P>0.05). The results revealed significant level suggesting possible cryptic demographic in Debao, Yunnan and Ningqiang pony. The exploit and conservation priorities about pony populations in China were determined according to the result of the present study.

Key words: microsatellite DNA; pony; Bottleneck; resource conservation
