Thai rice on the genebank menu

158826661 3Cb29Defdd M There was a slightly odd article at Seed Magazine a little while back on Thailand’s efforts to conserve almost extinct varieties of rice in its genebank. Odd because while the story is familiar enough in this kind of piece, the details are slightly confused (or confusing). But no matter, that’s probably only of concern to a pedant like me. The rest of you won’t worry about statements like “farmers across Asia once grew more than 100 varieties of rice, but now that number is down to only 20 or 30 of the most productive types”. Instead, you’ll be thrilled to know that the Thai national collection houses nearly 24,000 varieties, 17,000 of which “are in danger of dying out because they are no longer grown by Thai farmers”. That’s great because SINGER, a window on the world of genebank accessions, lists only 5982 samples from Thailand. Maybe one of those is “the fragrant Pin Kaew variety that was named the best rice in the world at a competition in 1966 but which has since disappeared, having lost out to more productive varieties”.

Rice stories

The BBC World Service is broadcasting a series of four programmes on the rice cultures of Asia, called Rice Bowl Tales. Starts 28 February, but if you miss it, it seems like the series has already aired on Radio National, and if you follow the link I’ve just given, you should be able to listen online or download audio files.

More on CWRs

I’ve gone back to my blog a few days back on crop wild relatives and expanded it somewhat. In particular, I’ve added links to several more recent papers on the subject. Should have probably done that in the first place. Sorry.

Starch grains and the origins of agriculture

A couple of papers discussed here and here (among other places: the chili pepper story in particular has been getting a lot of media coverage) describe how the minute, species-characteristic starch grains found in micro-crevices on stone tools and cooking utensils recovered from archaelogical sites are being used to study the domestication of crops as varied as maize, cassava and chilies in the Americas. The findings are pushing back the timing of domestication and suggesting that wet lowland areas were more important in the process than previously thought. Jeremy blogs on the chili angle at greater length here. No word on the past of cactus cultivation, at least in these papers, but this piece suggests its future may be troubled.
