Abstract

---

The N-band patterns of heterochromatin distribution in Hordeum jubatum chromosomes was studied to identify general patterns or preferential sites for heterochromatin. Mean number of Giemsa N-bands indicated that they are located mostly on the intercalary and centromeric regions and rarely on the terminal ends. Heterochromatic N-bands located at terminal and distal positions respectively on the satellites of first two pairs and the third pair had two bands in the middle and terminal portion of the satellite.
