抄録

To clarify the chromosomal evolution among the 3 sections (Absinthium, Artemisia, Dracunculus) of Japanese Artemisia, we use numerical cytogenetic analysis based on karyotypes. The intra- (A₁) and interchromosomal (A₂) asymmetry index, which does not depend on chromosome number or chromosome size. Our asymmetry index based on A₁ value has indicated that the chromosomes in some Japanese Artemisia evolved in order of section Dracunculus, Absinthium and Artemisia. The A₁ index indicated that x=9 was the ancestral basic chromosome number of this genus while x=8 was advanced, and based on x=17 was plotted between speies with x=9 and x=8.
