The Voice Of America has five podcasts/articles (I have no idea if the articles and the podcasts say the same things, as I haven't made it very far into either at this stage) on bananas:
Banana Mooted As Top Crop In Africa (1 of 5)
Disease Threatens Banana Industry (2 of 5)
Top Trade Lawyer Doubts Feasibility of East African Banana Exports to Europe (3 of 5)
Governments and Global Businesses Urged to Help African Banana Sector (4 of 5)
Sweeping Reforms Needed to Improve African Banana Industry (5 of 5)
I've thought a little bit about doing a fruit breeding podcast, but I'm not convinced it's worth the bother.
