Abstract

The N-band pattern of heterochromatin distribution in tetraploid Hordeum depressum chromosomes was studied to identify general patterns or preferential sites for heterochromatin. An ideogram was developed for the description of individual N-bands. The karyotype of H. depressum had 9 metacentrics, 3 submetacentrics and 2 SAT chromosome pairs with small spherical and elongated satellites. Giemsa N-banding patterns of H. depressum showed 6 bands per chromosome on an average. Mean number of bands indicated that it possessed 0.32 centromeric, 0.5 intercalary and 0.18 telomeric bands.
