Abstract

                                The importance of floral biological studies in projects aiming at crop improvement work is well known. The exact technique to be employed in breeding programme for the evolution of strains with desirable attributes is dependent on the selfed or open pollinated nature of the crops concerned, which itself is determined by the genetic and physical barriers existing in those crops. The present studies were therefore, carried out with four different cultivars of cepa or common onion from commercial sources with the same object in view.
