Almost all of the bananas we eat are of a single variety, Cavendish, grown to replace one wiped out by a virus in the 1950's.
But the virus has mutated, and is now deadly not simply to local strains, but especially to the Cavendish.

Quote:
For decades the most-exported and therefore most important banana in the world was the Gros Michel, but in the 1950s it was practically wiped out by the fungus known as Panama disease or banana wilt.
Banana growers turned to another breed that was immune to the fungus - the Cavendish, a smaller and by all accounts less tasty fruit but one capable of surviving global travel and, most importantly, able to grow in infected soils.
But just as breeders were busy cultivating their Cavendishes, so too was the Panama disease developing a new strain capable of killing them off.
And the new fungus is even more deadly than that which wiped out the Gros Michel, for it also affects numerous local breeds of banana around the world.
"Banana?"
