All species were diploid (2n = 2x = 24) with mean chromosome length of 15.86 µm. Four chromosome types (‘‘m’’, ‘‘sm’’, ‘‘st’’, ‘‘T’’) made five different karyotypic formula. Chromosome count of F. avromanica (2n = 2x = 24) is a new report. Analysis of variance for eight chromosomal parameters revealed inter specific chromosomal variation. Based on different karyotype asymmetry indices including TF %, CV %, A2, AI, AsK %, S%, F. assyriaca had the most asymmetrical karyotype. Based on Fluorescence in situ hybridization result, 4 and 6, 35S rDNA loci were observed for F. raddeana and F. persica respectively, which mainly located at distal or telomeric regions of chromosomes.
