Abstract

Meiotic chromosome behaviour in the genus Rubus is relatively normal Polyploidy occurs in both South African subgenera, i.e. Eubatus and Idaeobatus. The subgenus Eubatus contains plants tending mostly towards autoploidy. whereas the subgenus  Idaeobatus varies from autoploid, through segmental alloploid to alloploid. It is concluded that this apparent difference might be due to the study of a statistically insufficient number of plants and that alloploidy originated from imersubgeneric hybridization.
