STUDIES IN SOME SPECIES OF HORDEUM L.
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.
