摘　　要：Picea mongolica is a conifer with a limited distribution in China and its taxonomic status is controversial.In order to explore genetic diff erences between P.mongolica and other nearby Picea species and to investigate its taxonomic status,phylogenetic relationships were analyzed between P.mongolica and Picea koraiensis,Picea meyeri and Picea wilsonii by three chloroplast gene sequences matK,chlB and atpA.The length of joint chloroplast sequence is 2379 bp.The fi fteen haplotypes were identifi ed by haplotype network analysis,among which two were major haplotypes and nine were unique.In addition,the genetic diversity of the sample collection species was inferred.Based on the haplotype network and Neighbor Joining phylogenetic tree analysis,P.mongolica was located on the basal clade of the phylogenetic tree which had more primitive taxa,and the genetic diversity of P.mongolica was highest.The signifi cant diff erences between P.mongolica and these other Picea species were identifi ed by this research.
