A glass vial of beans is worth a thousand database entries

Check out one of the illustrations in Brainpicking’s review of a recent book on the Academy of Natural Sciences of Philadelphia (“which stands today as the oldest natural history museum in the Western Hemisphere,” and just celebrated its 200th anniversary). It’s the one labelled “Agricultural seed samples collected by Charles F. Kuenne, 1948,” towards the bottom of the page. I’m trying to find out who Mr Kuenne was. Or is. He’s not mentioned in GRIN, alas. But what I wanted to talk about was the sort of glass jars that he — and many others — used to store and display his seeds.

I always thought they were pretty useless, as you can virtually guarantee that the seeds will be dead in short order stored like that. Of course keeping them alive was not the point, and you can now extract DNA from much worse samples. But the fact of the matter is it that during last week’s trip to the CIAT genebank I saw bean breeders look at the assembled ranks of little grain-filled vials on display there so longingly, and lovingly, I cannot but revise my opinion.

Bean breeders discuss the CIAT collection.

Who needs fancy databases when you can just run your eyes past thousands of different bean samples in a few seconds? Having said that, if you search the CIAT database you will find the varieties Red Valentine (G07707) and Rust Proof Golden Wax (G09523) collected by Kuenne — though not his actual samples, of course. They’re in Philadelphia.

Multidisciplinary taro book on the way

The National Museum of Ethnology in Osaka has just announced the publication of what promises to be a fascinating book on taro:

M. Spriggs, D. Addison and P. J. Matthews (eds) (2012) Irrigated Taro (Colocasia esculenta) in the Indo-Pacific: Biological, Social and Historical Perspectives (Senri Ethnological Studies 78). Osaka: National Museum of Ethnology. 363 pp., with index.

According to one of the authors, “[t]his map from the preface shows main geographical coverage (areas 1 – 10) of the volume (there is also some extension to China and mainland SE Asia).”

All the chapters will soon be available on the Museum’s website, so keep a lookout.

Two things about agricultural biodiversity

If the point of a good blog post is to get you thinking, Alan Cann’s over at the Annals of Botany blog certainly worked on me. What are the two things you need to know about a subject? I’ve been pondering that since 18 March, when Alan’s post appeared. I had my answer almost immediately, but I haven’t been able to refine it as I thought I might.

A bit of background. Alan was riffing on an article in The Guardian, which in turn was building on a site kept (and now more or less abandoned) by economist turned screenwriter Glen Whitman. The basic idea is that

For every subject, there are only two things you need to know. Everything else is the application of those two things, or just not important.

So what are my two things?

  1. All intrinsic improvements in agriculture are founded on existing agricultural biodiversity.
  2. Improvements in agriculture intrinsically destroy existing agricultural biodiversity.

But I’m sure you can do better …
