The occurrence of polytenic nuclei in the anther tapetum of field grown variety K 5269 of a bean species, Vigna unguiculata has been recorded. There are pronounced polytene nuclei with chromocenters unassociated with chromatin bundles. In comparison to polytenic nuclei of other plants they were relatively smaller with a small nucleolus. These features of polytenic nuclei suggest low level of endoreduplication in Vigna unguiculata.
