Floral biology, Field Controlled Pollination and Hybrid Obtention of Dioscorea Dumetorum (Kunth) Pax) in Cameroon

Abstract

Introduction-There is very little literature on the floral biology, synchronization of maturity of male and female flowers, flowering phenology and controlled pollination of Dioscorea dumetorum (D. dumetorum). However, the genetic improvement of this yam species, which is widely consumed in Cameroon and has exceptional nutritional qualities, cannot be achieved without knowledge and understanding of these biological attributes or phenomena. The aim of this study was to (1) -examine the sexual reproductive biology of D. dumetorum; (2) -study the phonology of flowering in this plant species; and (3) -develop a pollination method in order to obtain hybrid seedlings.
