Karyotype of some species and varieties of Allium was studied. Except Allium stracheyi, all other species showed 8 as basic chromosome number. Cultivars of same species did not vary considerably in their karyotypes, although they were morphologically different. UPGMA based dendrogram and Principal co-orninate analysis were also employed to assess the phylogenetic relationships among the species and varieties. The dendrogram clearly separated the bulbous and non-bulbous forms of Allium. Principal co-ordninate analysis, however, slightly differed from the dendrogram and clearly separated A. stracheyi from other species.
