The genus Dianthus belongs to Caryophyllaceae family encompasses over 300 species in the world.The genus importance is mainly because of its ornamental species, the different in polidy level and varaition form, shape and flower size.Three wild species of this genus has been reported in Khorasan Razavi province ie. D. binaludensis, D. polylepis (endemic for Iran) and D. crinitus. In order to investigation of Dianthus karyotype, a study was carried out on nine populations of the mentioned species in Khorassan Razavi Provience. The basic chromosome number of Dianthus was reported X=15. The level of ploidy in D. binaludensis and D. polylepis were diploid (2n=30), while such a level was found to be tetrapoloid (2n=60) in D. crinitus. In addition, in the present research, for the first time, the karyotype of the three species of Dianthus were prepared and compared with the morphological characters.
