In order to investigate karyotipic variation between ten populations of Festuca arundinacea, cytogenetic study was performed. The populations were studied for several karyotypic characteristics, including long and short arm length, by which total length of the chromosomes, long arm to short arm and short arm to long arm ratios were calculated.Analysis of variance of mitotic data in factorial experimental design based on completely randomized design, showed highly significant differences between the studied populations for all of the traits at a=0.01 level. Duncan test were carried out in order to classify the populations and their chromosomes.All of the ten populations of the species had 21 chromosome pairs, without any sat-chromosome and B-chromosome. Chromosome total length range was 2.30-7.30 micron. Minimum total length of the chromosomes belonged to the of Semirom population and maximum total length of the chromosomes belonged to the Sirachal and Sanandaj populations. Based on the most karyotypic asymmetry measurements a foreign population called Barraco, was the most asymmetric and Sirachal population showed the most symmetric karyotype.
