Abstract
In this study pattern of heterochromatin dis-tribution at mitotic interphase and prophase stage of six wild Corchorus L. species, viz. C. brevicornatus, C. septentrionalis, C. urticifolius, C. hirtus, C. siliquosus and C. pinnatipartitus were investigated following orcein, CMA- and DAPI- staining. After orcein staining, interphase nuclei of C. brevicornatus, C. septentrionalis and C. urticifolius had 'Diffuse Type' while C. hirtus, C. siliquosus and C. pinnatipartitus had 'Simple Chromocenter Type'. In case of prophase chromosomes, C. septentrionalis and C. urticifolius were detected as 'Gradient Type', C. brevicornatus and C. hirtus as 'Continuous Type' and C. siliquosus and C. pinnatipartitus as 'Interstitial Type'. Distinct amount of CMA- and DAPI- fluoresced bands were observed in the studied six wild Corchorus L. species.
