Chromosomal Evolution in Some Iranian Artemisia L. using Numerical Analysis of Karyotypes

Abstract

A karyological study of seven taxa (four sections) of genus Artemisia L. from Azerbaijan region (Iran) is presented. We found the two usual basic numbers in the genus x=9, the most common one (in three diploid and two tetraploid populations) and x=8 (in two diploid populations).The intra- (A1) and interchromosomal (A2) asymmetry index, which does not depend on chromosome number or chromosome size showed asymmetry index based on A1 value has indicated that the chromosomes in some Iranian Artemisia evolved in order of section Absinthium and Artemisia meanwhile section Seriphidium and Dracunculus are close to each other but they can separate from Section Absinthium and Artemisia.
