VAHIDY, A.A. AND B. JAHAN
Abstract
Karyological studies in Hordeum species viz., H. bogdanii (2x), H. brachyantherum ssp, californicum (2x), H. brevisubulatum (4x), H. brevisubulatum ssp. nevskianum (2x), H. brevisubulatum ssp. turkestanicum (4x), H. bulbosum (4x), H, chilense (2x), H. comosum (2x), H. depressum (4x), H. jubatum (2x), H. marinum (2x), H. murimum ssp, leporinum (4x), H. lechleri (6x), H. roshevitzii (2x), H. secalinum (4x), H. stenostachys (2x) and H. vulgare ssp. agriocrithon (2x) were made using aceto-orcein staining technique. Detailed morphological observations of chromosomes included total length, arm ratio and presence of satellites. The cytological technique employed gave good spread of chromosomes, an important prerequisite for karyotype analysis.
