Abstract: We deals with karyotype data of three species of Atractylodes DC.from the North-east of China, their Karyotype formulae are as follow:Atractylodes chinensis (DC.) Koidz.K (2n)=24=12m+6sm+6st (4SAT), Atractylodes japonica Koidz.K (2n)=24=14m+10sm (4SAT), Atractylodes koreana (Nakai) Kitam.K (2n)=24=10m+14sm (4SAT).The symmetry of the Karyotype of three species is 2B separately.The somatic chromosome numbers of A.japonica and A.koreana are different from previous reports;Meanwhile infrageneric taxonomic treatment and evolutionary relationships are also discussed in this paper combining with morphological data.

Key words: Atractylodes DC., Karyotype, Chromosome
