Giemsa N- banding pattern in Hordeum Murinum

Giemsa n-banding pattern in some tetraploid taxon of hordeum murinum was studied. an ideogram was developed for each studied taxon of hordeum murinum for the description of individual n-bands. n-banded karyotype of tetraploid taxa of h. murinum had 4-6 bands per chromosome,subsp. murinum showed 5 and subsp. leporinum 6 bands per chromosome on an average. most of the bands were intercalary. the pattern showed high levels of band heteromorphism and banding pattern polymorphism but heteromorphisms were not observed between homologous chromosomes within these taxa.
