AHSAN A. VAHIDY AND BUSHREEN JAHAN
Abstract
An intervarietal chromosome banding polymorphism in 8 botanical varieties of Hordeum vulgare viz., convar. hexastichon vars: coelesle and ingrum; convar. distichon vars: inerme, pallidum and nulans; convar. vulgare vars: coelesle, horsfordianum and dwndarbeyi was studied by Giemsa N-banding technique. Chromosomes were numbered according to the wheat homoeologue groups. The classification of the bands was in accordance to the generalized cytological nomenclature of cereal chromosomes (GCNCC). Majority of bands recognized in all varieties were centromeric or interstitial. Band polymorphism was observed on all chromosomes except 1H, which exhibited typical banding pattern in all varieties.
