The Root Crops Agrobiodiversity Project in Vanuatu is inventorying varieties in various villages around the archipelago, and coming up with some astonishing results. ((Although an old Pacific hand of my acquaintance disputes the inclusion of the Solomon Islands in this statement from the press release: “In other Pacific archipelagos, such as New Caledonia and the Solomon Islands, the introduction by the Europeans of new root and tuber species, combined with the arrival of a market economy, has totally disrupted the existing systems.”)) But, crucially, the work will not stop there. One of the objectives of the project is “to identify new varieties aiming at broadening the existing genetic bases and to propose them to producers and users, taking into account their needs and preferences.” So it’s more than the usual 3Cs — collect-characterize-conserve. There’s also creation, and dissemination, of new diversity, via seed production. That’s not that easy to do with taros and yams, but then, neither is conservation in conventional field and in vitro genebanks. It’s a very sensible idea to get the diversity increasing and moving around, rather than locking it up on research stations.

Blogging the big birthday: Darwin the seed networker
Sure: “The Voyage of the Beagle,” “The Origin of the Species,” “The Descent of Man.” But also thousands of letters. Darwin corresponded widely, asking for information and opinions, checking facts. He was very scrupulous in giving credit, just look at the footnotes in his books. But actually the flow was not one-way. Yes, Darwin was a phenomenal networker. He would probably have had a blog.
His passion for networking extended to seed. He carried on a correspondence for some years with a Mr James Torbitt, a spirit merchant of Belfast. Torbitt had the idea that potato late blight might be overcome by using true seed. He wrote a treatise explaining how, and sent it to Members of Parliament and prominent landowners. With each pamphlet was a packet of 9,000 potato seeds. And he put an ad in The Times:
EXTINCTION OF POTATO DISEASE, with doubled or trebled crops – Modus operandi – Grow from seed. Exposure of plants to full force of infection. Destruction of those which succumb. Propagation of the by the sett. (In all places some plants will repel the attack of the parasite: in some, all). Seed supplied Address Robertson, Brooman and Co.; 150 Fleet Street, London. Or James Torbitt, Belfast, Ireland.
Torbitt asked Darwin for advice. Was he doing the right thing? Darwin assured him that he was.
Torbitt’s project illustrated in practice the idea of selection, which was a controversial issue among naturalists from the time of the publication of On the origin of species in 1859, and of the advantages of cross-breeding, hence Darwin’s … interest.
He allowed his name to be used in connection with the initiative, and pledged financial support: “between March 1878 and May 1881, through Darwin’s initiative, Torbitt received £410 from Darwin’s friends and relatives.”
Research on true potato seed continues. Darwin would have approved. And maybe even sent some money.

Blogging the big birthday: A taste of things to come
Tomorrow we will be celebrating the 200th birthday of Charles Darwin. Here’s a little foretaste:
Gallesio gives a curious account of the naturalisation of the Orange in Italy. During many centuries the sweet orange was propagated exclusively by grafts, and so often suffered from frosts that it required protection. After the severe frost of 1709, and more especially after that of 1763, so many trees were destroyed that seedlings from the sweet orange were raised, and, to the surprise of the inhabitants, their fruit was found to be sweet. The trees thus raised were larger, more productive, and hardier than the former kinds; and seedlings are now continually raised. Hence Gallesio concludes that much more was effected for the naturalisation of the orange in Italy by the accidental production of new kinds during a period of about sixty years, than had been effected by grafting old varieties during many ages. I may add that Risso describes some Portuguese varieties of the orange as extremely sensitive to cold, and as much tenderer than certain other varieties.
From The Variation of Animals and Plants Under Domestication (1868, p 308)
And in an astonishing display of the power of Google, Serendip, and my dodgy memory, the same Gallesio (seen above) chronicled the Citrangolo di Bizzarria, noted by Luigi almost two weeks ago.
