The pawpaw (Carica papaya L.) is the most economically important fruit in the Caricaceae Family. In some parts of the world, specially Australia and some islands of the West Indies, it is known as papaw, or pawpaw, names which are better limited to the very different, mainly wild Asimina triloba Dunal, belonging to the Annonaceae. While the name pawpaw is widely recognized, it has been corrupted to kapaya, kepaya, lapaya or tapaya in southern Asia and the East Indies. In French, it is papaye (the fruit) and papayer (the plant), or sometimes figuier des Iles. Spanish-speaking people employ the names melón zapote, lechosa, payaya (fruit), papayo or papayero (the plant), fruta bomba, mamón or mamona, depending on the country. In Brazil, the usual name is mamao. When first encountered by Europeans it was quite naturally nicknamed "tree melon". (Morton, 1987). Production areas are located in most tropical and sub-tropical countries (CRFG, 1998). The pawpaw is believed to be native to southern Mexico and neighboring Central America. It is currently cultivated in Florida, Hawaii, Eastern British Africa, South Africa, Sri-Lanka,
India, Canary Islands, Malaysia and Australia. It is now present in every tropical and subtropical country. Pawpaw was first described in 1526 by the Spanish chronicler Oviedo, who found it first on Panamanian and Colombian coasts. The fruit was rapidly propagated in the tropics, most likely due to the abundant and highly viable seeds.
