Abstract

We used polymerase chain react ion (PCR) to analyze mtDNA control region gene of 65 individuals from six populations. The results showed that there were lower haplotype diversity (H=0.622±0.138) and nucleotide diversity (π=0.386±0.00383) in Yingchun population, higher haplotype diversity (H=0.857±0.044) and nucleotide diversity (π=2.580±0.01914) in Tuqiang; Neither the estimate of Tajima's D nor that of Fu and Li's D deviated significantly from the neutral selection hypothesis (P>0.1) for six populations, showing no evidence of strong selective sweeps or balancing selection. Correlation analysis shows the genetic diversity was significant positive correlation with latitude (r=0.770) and altitude (r=0.719), significant negative correlation with annual average temperature (r=-0.519) and frostless days (r=-0.652), no significant correlation with longitude (r=-0.258) and annual precipitations (r=-0.205).
