Abstract :In this study, chromosome numbers and morphologies of six Onobrychis taxa [Onobrychis tournefortii (Willd.) Desv., Onobrychis albiflora Hub-Mor., Onobrychis hypargyrea Boiss., Onobrychis radiata (Desf.) Bieb., Onobrychis meschetica Grossh, and Onobrychis galegifolia Boiss.] were investigated with the squash preparation method. These taxa belong to the Hymenobrychis section, including two endemic species naturally grown in Turkey. First, karyotype analysis of the Onobrychis meschetica was performed. Then mitotic metaphase and basic chromosome numbers of the taxa were determined in 2n=14 and x= 7, respectively. Chromosomes showed differences as median to submedian according to centromer position. Except O. meschetica, all of the taxa generally included a satelite on chromosome I or IV.Keywords : Onobrychis, chromosome, karyotype, centromer position
