Banana production in Panama that United Brands would expand its production in Panama because bananas could be produced more cheaply in Costa Rica and Ecuador. The history of banana production in Panama virtually coincides with that of United Brands, which has been in Panama since 1899. The company built railroads, port facilities, and storage areas for the processing and export of bananas. In the 1930s, a disease seriously curtailed banana production. In the 1950s disease resistant plants were developed, and production increased rapidly. In the early 1970s, a "banana war" erupted when banana-producing countries disagreed among themselves and with United Brands about an export
Crop diversity can be the result of genetic differences: a crop may have genes conferring early maturity or disease resistance Such traits collectively determine a crop's overall characteristics and their future potential. Diversity within a crop includes genetically-influenced attributes such as seed size, branching pattern, height, flower color, fruiting time, and flavor. Crops can also vary in less obvious characteristics such as their response to heat, cold, a drought, or their ability to resist specific diseases and pests. Modern plant breeders develop new crop varieties to meet specific conditions. A new variety might, for example, be higher yielding, more disease resistant or
