Abstract:The nuclear type formula of Polygonum mutiflorum Thunb. was reported in this paper, which was K(2n)=22=14m+2n (SAT)+6Sm and belongs to the type of ?B? The relative length composition of chromosome was 2n=22=2L+8M₂+12M₁. Some foundations were offered for the breeding and taxonomy of Chinese traditional medicine.

Key words: Polygonum multiflorum Thunb.; chromosome; nuclear type analysis
