Notes:
Summary The breeding system of Solanum integrifolium has been studied with the view of setting up a breeding programme. Three flower types are distinguished on the basis of style length. The results of crosses among these types have elucidated that only long-style flowers are female-fertile. The medium and short-style flowers are unable to set fruits. Some of the flowers, irrespective of their stylar morphism, also exhibit male sterility which is uncommon in Solanum. The biological significance of the stylar heteromorphism has been discussed in relation to evolutionary trends in the genus and the probable cause of this phenomenon speculated upon.
