Dessert bananas for world food trade are almost entirely derived from genetic make ups of Musa acuminate of triploid character, indicated as AAA. Plantain (Musa AAB) and other cooking bananas (Musa ABB) are also triploid and derived from the AA × BB hybridisation. Plantain and cooking bananas are very similar to unripe dessert bananas in outward appearance, although often larger. The major differences are that their flesh is starchy rather than sweet, that they are used unripe, and require cooking.
