A Nibble big enough to choke on

Yeah, yeah, it’s been quiet here for the best part of a month. Work, you know. When you notice lack of action here, though, that doesn’t mean that I’m being completely idle. Not always, anyway. Check on Twitter and Facebook, if you dare, and you’ll see new stuff on a fairly regular basis, because that’s easier to do than a fully-fledged blog post. Anyway, what I’ll do here is a mega-Nibble hoovering up snippets from the past few weeks that I posted on social media but not here.

Where to find stressed rice in Nigeria

So last week’s Brainfood led with a paper mapping various abiotic stresses affecting rice in Africa, noting that the next step would be to mash up the results with germplasm provenances.

Well, I decided to do it myself. Here’s the distribution of “iron-rich soils” in Nigeria and potentially affected rice area (the paper’s Fig. 8b), the latter coming from the SPAM project we have alluded to before as a source of data on crop cultivation.

The yellow rings are African rice landraces, the red dots all rice landraces, both from Genesys. If you click on the map, you’ll see it much better, and notice that there’s not much rice germplasm from the more brownish areas, denoting rice cultivation areas with Fe-richer soils. Should these be targets for collecting? Kind of depends if landraces are still grown in those places, but it’s a start.
