　　The genus Bromus L.,is among the most important forage plants of Iran distributed wildly in different regions of the country.The genus Bromus comprises several annual as well as perennial grass species.The section Genea Dum.is among annual Bromus grasses.meiotic analysis revealed the presence of 2n=14(2x) and 2n=28(4x) chromosome number among the species and populations studied.The two populations of B.sericeus studied differed in their ploidy level.
