Reconstructing bread wheat introduces novel genetic diversity.
One up, one down
Following on from Luigi’s post a month or so back about the probable return of the chestnut to American woods, two stories, on consecutive days, from the Christian Science Monitor. One gives more information about the complex breeding programme that involves Chinese chestnuts, resistant American trees and lots of painstaking crosses to produce blight-resistant chestnuts. That work has been going on since the early 1980s, and may now be close to complete. A few days earlier, the paper reported on the threat to the Eastern Hemlock, a woolly bug, originally from East Asia. Adelges tsugae has been slowly spreading across the US, where the only hope seems to be a decent cold winter. The fear is that the Eastern Hemlock will go the same way as the Carolina Hemlock, which once shared the forests with the American chestnut and which, experts fear, could now be eaten out of existence.

Seed sleuth
There’s a glowing portrait of Ken Street, a plant hunter, in the Sydney Morning Herald. Street works with ICARDA, the International Centre for Agricultural Research in the Dry Areas, based in Aleppo, Syria and spends much his time in the wilds of central Asia, searching out crop diversity. The piece is a bit gushy for my taste, and I’m not sure I agree with everything Street is quoted as saying. “We have been eating genetically modified organisms for 10,000 years” turns the phrase “genetically modified organisms” into meaningless guff. But he does make some good points about the amount of diversity that survives — for now — in places like Armenia and Tajikistan. If you want a glimpse into the life of a man they call “an agricultural Indiana Jones,” that’s what you’ll get.

Buckwheat musings
Greetings from Nairobi. I’m here for a week’s rest and relaxation, which does not of course preclude blogging! Anyway, what I wanted to write about has nothing to do with Kenya. Or at least I don’t think buckwheat — our subject this evening — is grown here. It all started a week back when I went up to Lucca, near Pisa, for the weekend. That included a lot of eating, of course, and one of the dishes that particularly struck me was a main course composed of a thin tortilla-type thing, folded up, and filled with a nice sauce. I can’t remember the name of the dish, but the tortilla was made of “grano Saraceno,” according to the menu. I hadn’t heard the name, but a little snooping confirmed it to be buckwheat. A rarish crop in Italy, but nevertheless the basis of some interesting traditional recipes. Now, I knew a little about buckwheat, but next to nothing about its nutritious relative, Tartar(y) buckwheat. And I certainly didn’t know that there’s an easily de-hulled variety of this crop called rice-tartary which promises to be a boon to breeders. Nor that you can emasculate the flowers with hot water, which could also be useful if you’re trying to make crosses. I should eat out more.
