Banana is a general term embracing a number of species or hybrids of the genus Musa of the family Musaceae which is cultivated in more than 100 countries throughout the tropics and subtropics. Musa is one of the cheapest food crops to produce and the cost of production is less than most other staples. The banana cultivars originated from the intra- and inter-specific hybridization of two wild diploid species, Musa acuminata Colla and Musa balbisiana Colla , contributing the A and B genomes respectively. In terms of gross value of production, bananas are the developing world’s fourth most important crop after rice, wheat, and maize. The bulk of the banana is eaten as raw and only a very small proportion are processed in order to obtain a storable product. They are harvested unripe and green, because they can ripen and spoil very rapidly.
