In a field of mature bananas, plants can be seen at all stages of
vegetative growth and fruit maturity, providing a fascination for anyone
who has an interest in growing crops. Banana farmers in the tropics can
harvest fruit every day of the year. The absence of seasonality in
production is an advantage, in that it provides a continuity of
carbohydrate to meet dietary needs as well as a regular source of
income, a feature that perhaps has been under-estimated by rural
planners and agricultural strategists. The burgeoning interest in
bananas in the last 20 years results from the belated realization that
Musa is an under-exploited genus, notwithstanding the fact that one
genetically narrow group, the Cavendish cultivars, supply a major export
commodity second only to citrus in terms of the world fruit trade.
International research interest in the diversity of fruit types has been
slow to develop, presumably because bananas and plantains have hitherto
been regarded as a reliable backyard source of dessert fruit or starch
supplying the needs of the household, and in this situation relatively
untroubled by pests, diseases or agronomic problems.
