Chromosome number and meiotic behaviour of two populations of Onobrychis subnitensis Bornm. (O. sect. Hymenobrychis) in Iran

The genus Onobrychis belongs to family Fabaceae and has about 130 species throughout the world. Onobrychis sect. Hymenobrychis with nearly 15 species in Iran is one of the important sections of the genus. Most cytological studies in the genus have concentrated on the chromosome count with little work focused on detailed karyological criteria. In this research, the chromosome number and meiotic behaviour were studied in two populations of Onobrychis subnitensis belonging to this section native to Iran. This report is the first cytogenetic analysis of this taxon.
