Ghamarv Zareʹ, A., Member of Scientific Board of Forests and Rangelands Research Institute Iran. A karyological study of six taxa (eight populations) of the genus Artemisia L. from different geographic origins in west Azarbaijan province is presented. The work deals with chromosome number and their morphometry. We found the two usual basic numbers in the genus: x=9, the most common one (in two diploid and three tetraploid populations) and x=8 (in three diploid populations).Through ocular micrometry, five metaphase cells were studied from each population for several karyotype parameters, including long and short arm length. Using several estimating formula, karyotype asymmetry of the populations were investigated. Detailed karyotype analyses allowed us to group the different populations to investigate their relationship and evolutionary trends.
