Episode notes
India Dominates Production But Not Exports
- Bananas are the world's most produced and consumed fruit with Indians eating about 70–80 a year each.
- India makes ~35 million tonnes annually but exports only ~1% due to small landholdings and uneven post-harvest quality.
How Cavendish Became The Supermarket Banana
- The Cavendish replaced Gros Michel after Panama disease wiped out Gros Michel in the mid-20th century.
- Gros Michel was preferred for shipping but Fusarium (Panama disease) devastated it, forcing a global switch to Cavendish.
Monoculture Makes Cavendish Susceptible
- The Cavendish's apparent vulnerability comes from genetic uniformity: most commercial bananas are cloned seedless plants.
- Clonal monoculture means a pathogen like TR4 can infect entire crops because plants lack genetic diversity.
