Abstract
The genus Aegilops is one of the most important genera of the Poaceae family. It belongs to the tribe Triticeae with 12 species in Iran. The research karyological analyzed in 12 populations of 4 Aegilops species: A. umbellulata Zhuk., A. tauschii Coss., A. columnaris Zhuk. and, A. triuncialis L. were done. We used fresh grown root tips. Then α-bromonaphtaline, formaldehyde and chromium trioxide (1:1), 1 N NaOH and hematoxiline were used for pre- treatment, fixative, hydrolyser and chromosome staining agent, respectively. We used video Analysis system for each species with Micromeasure software. All populations in the secondary basic numbers were x=7. The ploidy levels were different. In A. tauschii and A. umbellulata were found 2n=14, and A. columnaris and A. triuncialis were found 2n=28. Detailed karyotype analysis allows us to group the different species and to postulate relationships among them.
