- Push-pull pulls in prize.
- Which is more than can be said for the Millennium Villages Project. I wish someone would occupy them.
- You can have too much good breeding. If you’re a horse.
- Nice aerial pics of rice cultivation. And a sort of information service on that cereal called Rice 2.0, which unaccountably lacks an RSS feed.
- WorldFish invites entrepreneurs to get together and discuss investing in aquaculture. Here’s hoping diversity won’t be left in the dust.
Brainfood: OSP adoption, Milk quality, Passport data quality, Historical collections, Sweet potato domestication, African veggies, Baobab diversity and domestication, Cassava diversity, Strawberry breeding, Barley GWA, Pest symbionts, Maize diversity and climate change
- A large-scale intervention to introduce orange sweet potato in rural Mozambique increases vitamin A intakes among children and women. Just 1 year of training worked just as well as a higher intensity intervention (3 years) in increasing OSP and vitamin A intake by younger children, older children and women, and decreasing prevalence of inadequate vitamin A intakes. OSP represented about half of all sweet potatoes consumed so I guess there was not complete replacement of local varieties.
- Composition of milk from minor dairy animals and buffalo breeds: a biodiversity perspective. There are significant interbreed and inter-species differences. Dromedary milk is closest to cow milk, mare and donkey milk maybe the healthiest, but moose milk is the one I’d like to try.
- Quality indicators for passport data in ex situ genebanks. That would be the genebanks in Eurisco. Verdict: not bad, but could do better. Most variation in quality is among institutes.
- Exploring the population genetics of genebank and historical landrace varieties. Old samples of dead seeds of 4 crops in Swedish museum jars more genetically variable than genebank accessions, but it’s not the genebank’s fault. And at least their seeds are still alive. Also no genetic correspondence between geographically matched museum and genebank samples.
- Combining chloroplast and nuclear microsatellites to investigate origin and dispersal of New World sweet potato landraces. Two areas of domestication, probably from a single wild progenitor species: lowland NW South America and lowland Central America/Caribbean. Genetic differences between these 2 genepools not accompanied by morphological differences, but then again nobody’s looked properly, and the current descriptors are useless anyway.
- The significance of African vegetables in ensuring food security for South Africa’s rural poor. Their huge potential is being thwarted by evil extensionists. Ok, but don’t we need to move beyond that?
- Comparative study on baobab fruit morphological variation between western and south-eastern Africa: opportunities for domestication. Hang on a minute, aren’t there a million factsheets about all this?
- Marriage exchanges, seed exchanges, and the dynamics of manioc diversity. Kinship structures determine cassava diversity patterns in Gabon. Matrilineal societies have more diversity.
- Interspecific hybridization of diploids and octoploids in strawberry. You get pentaploid and tetraploid plants.
- Genome wide association analyses for drought tolerance related traits in barley (Hordeum vulgare L.). Ok, deep breath. Over 200 accessions, both wild and cultivated, from 30 countries, so quite variable, but also structured. There were some QTLs that differed between dry and wet sites, but they didn’t explain much phenotypic variation, and they couldn’t be related to previous work. So GWA not much use, probably because of population structure. But couldn’t that have been predicted? And isn’t it possible to do something about structure in the analysis?
- Population genetics of beneficial heritable symbionts. Of insects, that is. Mostly proteobacteria. So my question is, could somehow attacking the symbionts form the basis of a pest management strategy?
- Projecting the effects of climate change on the distribution of maize races and their wild relatives in Mexico. Many races and wild relatives are predicted to shift in geographic distribution. Unless of course agronomy intervenes. Teocinte taxa should be collected.
Nibbles: Q&A, Zoopharmacognosy, Pigeonpea genome, Turkey, Wheat relatives
- Everyday agriculture mysteries solved.
- Other animals self-medicate too.
- Dueling pigeonpea genome sequencers? Who knew. Well spotted, James.
- I’m thankful for turkeys.
- And for the crop wild relatives in ICARDA’s genebank too.
Nibbles: Heirloom cattle, Saleb, Wheat protein, Dog domestication, Rooibos
- Why Highland Cattle? Because they look so cool, of course.
- It’s sahlib time!
- Australians find the extra gluten protein gene they need in Italian wheat.
- Where the hell was the dog domesticated?
- Rooibos tea is latest climate change victim.
Nibbles: Cassava bad and good news, Soybean domestication, Bitter gourd, Drought, Agrobiodiversity job, Heirloom turkey, Eurisco, Artisanal wheat, MSB, Food culture
- FAO really very worried about cassava. Does it know that the CGIAR has the technology?
- In today’s “crop X domesticated earlier than usually thought” story, X = soybean.
- The Deccan Chronicle discovers the Bitter Gourd Project and likes what it sees.
- How to drought phenotype crops.
- The Christensen Fund has a position open for a Program Associate – Agrobiodiversity and Biocultural Landscapes. Damn, that sounds interesting.
- “But, miraculously, the Ghost Turkey survives.”
- Eurisco has a new website!
- Artisanal wheat on the rise. I love the quip in the caption.
- Vancouver ♥ Millennium Seed Bank, and fawns over faux royalty.
- Amaranth and pizza offer entreés to culture and politics.
