摘　　要：应用扩增片段长度多态性(AFLP)技术研究鹀科8种28只鸟类的亲缘关系及遗传多样性.28只个体分为两类,A类包括所有鹀属鸟类,B类包括铁爪鹀属和雪鹀属的铁爪鹀和雪鹀.将A和B类中的不同物种分为不同分支:栗斑腹鹀与三道眉草鹀和白头鹀为一支,芦鹀、红颈苇鹀和苇鹀为一支,结果表明它们之间具有较近的亲缘关系.其中雪鹀和铁爪鹀位于分支的最底部,支持了其应从鹀属中分离的观点.An amplified fragment length polymorphism（AFLP） method was used to investigate the relationship and genetic diversity of 28 individuals from 8 species.Twenty eight individuals were divided into two distinct clusters：cluster A included all of birds from Emberiza,cluster B included Calarius lapponicas and Plectrophenax nivalos from Calarius and Plectrophenax respectively.Within these two clusters,subclusters formed largely on the basis of species.In all the clusters,Emberizidae jankowskii,Emberizidae cioides and Emberizidae leucocephalos were grouped into one branch,while Emberizidae schoeniclus,Emberizidae pallasi and Emberizidae yessoensis were grouped into the other branch.This indicates that they have blood relationships.C.lapponicas and P.nivalos in the bottom of the branchs supports that they should be separated from Emberiza.
