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