Melon (Cucumis melo L.) is an important crop cultivated world wide. It belongs to the genus Cucumis (Kirkbride 1993). C. melo is a diploid (2n=24), allogamous and insect-pollinated species. Widely considered as originating from East Africa, recent phylogenetic data on the Cucumis genus demonstrated that C. melo originates from Asia, together with its closely related species C. sativus (Sebastian et al. 2010; Telford et al. 2011).
