The particular problem strain of the Panama disease affects the Cavendish specifically. This has happened before; the Cavendish, itself, only became the dominant cultivar after other strains of the same disease killed the previous dominant cultivar, the Gros Michel. All members of a given cultivar are clones, so they&#x27;re genetically identical and thus very susceptible to being wiped out by disease as they have no mechanism to evolve resistance. We&#x27;ll probably just have to switch again.
