The business of bananas and apples
Quite by chance, two items that give insights into the backstory behind the No. 1 and No. 2 fruits in the world.
The always intriguing Nicola Twilley takes her class (Artificial Cryosphere) on a tour of New York’s biggest banana handler. Sure, we all know that the banana is the industrial fruit par excellence, but I guarantee Nicola’s report will open your eyes. And give you a million conversation stoppers, should you ever need them. Did you know, for example, that a recently gassed banana ripening room smells “like a wine-soaked carpet, the morning after”?
Next up, the patented, “managed variety” apple SweeTango®. I heard an interview with journalist John Seabrook at NPR, although unfortunately the New Yorker article that got him invited to talk about SweeTango® in the first place is not available for free. Among several fascinating elements in the story, I was struck by the control that the University of Minnesota is exercising over SweeTango®, which has its own website. Farmers cannot just sell direct to supermarkets or wholesalers. They have to sell back to a consortium established by the University, which aims to keep quality standards high. I wonder how much the University will make on the deal. I also wonder whether, like some of the DOC wines here, excess apples might be found for sale, unlabeled, at the side of a Minnesota county road. And it looks like there’s a lot more to Seabrook’s article than SweeTango®, about apples and apple breeding in general.
Nibbles: Push-pull award, MVP review, Thoroughbred breeding, Rice info, Aquaculture Clinic
- Push-pull pulls in prize.
- Which is more than can be said for the Millennium Villages Project. I wish someone would occupy them.
- You can have too much good breeding. If you’re a horse.
- Nice aerial pics of rice cultivation. And a sort of information service on that cereal called Rice 2.0, which unaccountably lacks an RSS feed.
- WorldFish invites entrepreneurs to get together and discuss investing in aquaculture. Here’s hoping diversity won’t be left in the dust.
Nibbles: Taiwan seedbank, American agroforestry
- Taiwan should establish a national seed bank. It says here. But will it be a genebank?

Conservation status of European crop wild relatives assessed
The latest IUCN assessment of the conservation status of European biodiversity is out, and is making the news. The bit on plants is co-authored by Melanie Bilz, Shelagh P. Kell, Nigel Maxted and Richard V. Lansdown and, unsurprisingly perhaps given their track record, includes, I believe for the first time, extensive discussion of crop wild relatives as a distinct class. 1 The authors, which coordinated input from dozens of experts, conclude that out of a total of 591 CWR species:
Within the EU 27, at least 10.5% of the CWR species assessed are threatened, of which at least 3.5% are Critically Endangered, 3.3% Endangered and 3.8% Vulnerable – in addition, 4.0% of the species are considered as Near Threatened. One species, Allium jubatum, is Regionally Extinct within Europe and the EU; it is native to Asiatic Turkey and Bulgaria, but has not been found in Bulgaria since its original collection in 1844.
It does not even seem to be available from botanic gardens, according to Botanic Gardens Conservation International’s database. I don’t know what has caused its disappearance in Bulgaria, but currently the main threats to CWRs seem to be intensified livestock farming, tourist development and invasives:
And there are maps 2 of both the distribution of overall CWR species richness and of the most threatened species:
An extremely useful review is provided of previous work assessing the extent to which CWRs are conserved in genebanks, botanical gardens and protected areas in Europe. But here perhaps I would like to quibble with the authors. Although their listing of existing conservation efforts seems to me thorough and comprehensive, there is no attempt made to synthesize the results of all the different initiatives and come up with a list, however preliminary, of high priority plants for immediate conservation intervention. Surely it would not have been particularly difficult to cross-reference their list of threatened species with listings of accessions in Eurisco and the BGCI database, for example. Maybe this was beyond the scope of this particular exercise and is the focus of parallel work. Perhaps Nigel or Shelagh will respond here.
This is a very important contribution to raising the profile of CWRs within the biodiversity conservation community. Let us hope that it will translate into increased support for their conservation, both ex situ and in situ, along the lines so usefully set out by the authors in their recommendations.
