Farming relicts in peril in Georgia

From our friend and colleague David comes news of a paper on erosion of crop genetic resources in Georgia. The one in the Caucasus, not the southern US. Anyway, good to be reminded that it’s not just species that are in trouble, but also crop varieties.

There are some nice B&W photos in the article, including this one of a threshing board, which reminded me of one of our earliest posts.

The bottom line?

…in Georgia the main reason for genetic erosion of ancient crop varieties is demographic decline in mountain regions due to harsh economic conditions and lack of modern infrastructure.

Wait. So if there were more people in the mountains, and better roads, there would be more landraces? All those people wouldn’t be growing modern varieties and trucking the harvest to markets in the cities?

Pavlovsk: you are here

Chaffey’s regular words of wisdom on anything botanical. Well, mostly wise. But more on that later…

That’s from a nibble a few days ago. The qualification concerned Pavlovsk, and Jeremy has now set the record straight. Incidentally, the latest update on the situation from the Vavilov Institute itself has the first decent map of Pavlovsk I’ve seen. Here it is. Explore for yourself: no Street View, alas.

Map of the Pavlovsk Research Station. Yellow: border of the station; Red: border of disputed plots; Green: border of the fruit and berry collection.

  • The value of Pavlovsk. Jeremy delivers a slap.
  • CIRAD on kinky sex among the baobabs.
  • “I had never heard that there were distinct varieties of the jackfruit, although of course such a thing was reasonable, so I naturally wanted very much to taste one.” Naturally.
  • Wild relative of pea gets a weird hybrid in-ex situ conservation treatment.
  • A Cowpea Story, an illustrative children’s book by Vicky Inniss-Palmer, tells the hopeful story of a cowpea named Catalina and her struggle to overcome illness and disease with the help of scientists. Meanwhile, scientists meet.
  • Urban gardeners, beware lead. And nurture your pollinators.
  • Reading this, anyone would think nobody had ever researched banana Xanthomonas wilt.
  • Improved dairying in Kenya.
  • Vavilov Institute’s comprehensive update on Pavlovsk.
  • ICRISAT to put in place new market-oriented strategy which will use a “systems perspective in setting our priorities to ensure that all important issues along the dryland agriculture value chain are addressed.”
  • Meanwhile, ASARECA asks for ideas on how to intensify one of those dryland systems in the face of climate change.
  • ICIMOD promotes herbal gardens in schools.
  • Botanic gardens get wrists slapped over their inattention to genetics.

Brassica bounty

Couldn’t resist today’s trifecta of Brassica papers. At the meta level, there’s “Origin and Domestication of Cole Crops (Brassica oleracea L.): Linguistic and Literary Considerations” in Economic Botany. Then some of the same authors follow up in GRACE with “AFLP analysis of genetic diversity in leafy kale (Brassica oleracea L. convar. acephala (DC.) Alef.) landraces, cultivars and wild populations in Europe.” And finally, in Plant Breeding, enjoy “The cytoplasm effect comparison between Brassica napus and Brassica carinata on floral characteristics of Brassica oleracea.” Enough to keep brassica boffins busy for weeks.
