also are eaten fresh. • Most of bananas in the U.S. are the latter type.
Primitive, probably diploid, banana
Balick and Cox, Plants, People, and Culture
• In the tropics, most gathered wild or cultivated on a local scale and consumed locally.
• Bananas, citrus crops, pineapples, mangoes, and avocados are major exceptions.

Tropical Fruits and Nuts: Outline
The rise of bananas as a cultivated crop is linked to the hiFra Baidu bibliotektory of the United Fruit Company.
In 1900, the company developed a good transport system to ship bananas to market.

Tropical fruits in a Queensland market
Introduction
• Many types of tropical fruits. Some exotic and not found commonly in temperate regions of the world.
They perfected the conditions to ship the fruits without spoilage and to ripen them at exactly the proper time for market.
They also dominated the politics of many Central American countries.
• More types of fruits in the tropics than in temperate portions of the world
• Few previously known here. The situation has changed in recent years. Many exotic tropical fruits are "in".
• Bananas reproduced vegetatively. This leads to many fungal disease problems.
• See figures pg. 94.
• Others are well-known cultivars such as tomatoes, squash, green peppers and cucumbers.
• Most of the other types of tropical crops are perennials that cannot be cultivated in temperate zones of the world.

Banana leaves and plantains
• Most banana species have seeds. • Common cultivars are sterile triploids. • Most bananas in the tropics cooked, but many
• See the table of tropical fruits and nuts on pg. 76.
• Tables of production, p. 77.
Bananas
• Bananas (Musa sp., Musaceae) are from southeast Asia. The taxonomy is complex. They were early taken to Madagascar and Africa by the Indonesians. In 600 B.C. they were in India. Alexander the Great saw them there. In 1522 in West Africa. To the Americas by 1516.
• Other evidence indicates that bananas were also domesticated in east Africa at an early date.
