SECTION 1 
 
Going Bananas 
 

The world's favourite fruit could disappear forever in 10 years’ time. The banana is 
among the world’s oldest crops. Agricultural scientists believe that the first edible 
banana was discovered around ten thousand years ago. It has been at an evolutionary 
standstill ever since it was first propagated in the jungles of South-East Asia at the end 
of the last ice age. Normally the wild banana, a giant jungle herb called Musa 
acuminata, contains a mass of hard seeds that make the fruit virtually inedible. But now 
and then, hunter- gatherers must have discovered rare mutant plants that produced 
seed-less, edible fruits. Geneticists now know that the vast majority of these soft-fruited 
plants resulted from genetic accidents that gave their cells three copies of each 
chromosome instead of the usual two. This imbalance prevents seeds and pollen from 
developing normally, rendering the mutant plants sterile. And that is why some 
scientists believe the world's most popular fruit could be doomed. It lacks the genetic 
diversity to fight off pests and diseases that are invading the banana plantations of 
Central America and the small-holdings of Africa and Asia alike. 

In some ways, the banana today resembles the potato before blight brought famine 
to Ireland a century and a half ago. But "it holds a lesson for other crops, too", says 
Emile Frison, top banana at the International Network for the Improvement of Banana 
and Plantain in Montpellier, France. "The state of the banana,, 

Frison warns, "can 
teach a broader lesson the increasing standardisation of food crops round the world is 
threatening their ability to adapt and survive." 

The first Stone Age plant breeders cultivated these sterile freaks by replanting 
cuttings from their stems. And the descendants of those original cuttings are the 
bananas we still eat today. Each is a virtual clone, almost devoid of genetic diversity. 
And that uniformity makes it ripe for disease like no other crop on Earth. Traditional 
varieties of sexually reproducing crops have always had a much broader genetic base,
