If you’re interested in Central Asian biodiversity and its products you might enjoy some recent photographs of mine from Tashkent’s central fruit and veg market. And if you recognize something interesting, and know its local name, do please leave a comment.
Nibbles: LEISA, climate change in the US and India, Cocoa
- ILEIA celebrated 25 years with a conference yesterday. Reports to appear on the blog. h/t Danny
- Summary of the big ag bash in Copenhagen.
- US fruits and vegetables most at risk from climate change, says USDA.
- Wine and corn (maize) too!
- Perhaps they could learn from Indian farmers?
- Cocoa price highest for 32 years. Good news for cocoa farmers? I doubt it.
Nibbles: Mutton, Vegetaballs, Orchids
- Why real farming needs great cooking. Upland mutton? I’d eat that.
- Down-your-throat vegetarianism. Justine bouche? I’d eat that.
- Orchid cuisine in Bhutan. Olachotho? I’d eat that.
Nibbles: Glomus, Erosion, Horticulture, Sweet potato, Drought
- Arbuscular mycorrhizal fungus spread by human activity related to agriculture.
- UN food security expert says “75 per cent of agro-biodiversity has been lost”. Naughty.
- UC Davis to lead big USAID-funded international horticulture development project.
- Botany Photo of the Day: Vitis labrusca.
- “The connection between a convolvulaceous tuber bearing crop, a folk-blues artist and a cetacean…”
- IWMI maps drought. Globally.
Tracking down P efficient brassicas
In following up a recent University of Nottingham press release (nibbled a few days ago) on a project to breed vegetables with higher levels of Ca and Mg I came across an earlier, related project by the principal investigator, Dr Martin Broadley. This was to evaluate P-use efficiency (PUE) in Brassica oleracea as a model system. There’s lots of genetics, but also this objective:
Determine the PUE of up to 50 commercial B. oleracea varieties and 400 varieties from the HRI Genetic Resources Unit (GRU) representing a wide geographical and genetic distribution of B. oleracea and close relatives
And this deliverable:
A database of Brassica oleracea PUE phenotypes. This database will identify the range of PUE in modern varieties. This will allow varieties to be matched to their nutritional environment. The range of PUE found in accessions in the HRI-Genetic Resources Unit (GRU) will also be defined. This database will be delivered to growers, via a summary factsheet and subsequent consultation.
Cool, I thought. Rather complicated evaluation information on an important collection made readily available to users (breeders, growers, researchers) in a natty database. I had visions of Andy Jarvis and his crew mapping the provenance of accessions on soils base maps to look for correlations between PRU and low P. Problem is, though the dataset is probably somewhere on brassica.info, I wasn’t able to track it down in over half an hour of messing around. No doubt I’m missing something which is right in front of my nose. Alas, the link provided in the project final report seems to be broken. I suspect the data I’m looking for is lurking in the supplementary tables on the project webpage at Defra, but a bunch of spreadsheets is not really what was promised. Another soul-sapping foray into genebank database hell.
