| Abstract | ||
| The genus Onobrychis in the family of Papilionaceae has 56 species in Iran. These species have been adapted to various climates of the country. Therefore, they are valuable germplasm for applied plant breeding. Karyotype study of different species of a genus is a primary work but basic step in cytogenetical studies because kariotype study provides valuable information for the researchers. In this work, eight species were studied. Plant and seed samples were collected from different habitats of Fars province. Different treatments were applied to root tip meristems to get cells in metaphase stage. Results showed that Onobrychisgaubae, O. melanotricha, O. aucheri ssp Teheranica and O. sojakii with 2n = 16 chromosomes and O. ptolemaica with 2n =14 chromosomes are diploids. O. aucheri ssp. psammophila and O. crista-galli with 2n=32 chromosomes and O. vicifolia with 2n=28 chromosomes are tetraploids. These results also showed that the genus Onobrychis has two genome numbers (x= 7 or 8) which corresponds to the previous researches. | ||
