- Benefit–Cost Analysis of Increased Funding for Agricultural Research and Development in the Global South. Fancy model says funding agricultural research is great value for money. Ok, let’s see if we can find some examples.
- Exploring CGIAR’s efforts towards achieving the Paris Agreement’s climate-change targets. Yeah, but in designing such research to mitigate climate change there should be more complete integration of food-systems perspectives.
- Crop species diversity: A key strategy for sustainable food system transformation and climate resilience. Now there’s a nice thing to integrate into your climate change adaptation and integration research.
- Cultivating success: Bridging the gaps in plant breeding training in Australia, Canada, and New Zealand. Gonna need more plant breeders also, though.
- Artificial intelligence in plant breeding. Yeah, and probably more artificial intelligence too.

- Enhanced radiation use efficiency and grain filling rate as the main drivers of grain yield genetic gains in the CIMMYT elite spring wheat yield trial. Gotta wonder if there’s a limit though.
- Origin and evolution of the bread wheat D genome. Maybe we can squeeze a bit more out of the D genome. I wonder what AI says about that.

- Deep genotyping reveals specific adaptation footprints of conventional and organic farming in barley populations — an evolutionary plant breeding approach. An initial, diverse barley population is allowed to adapt to contrasting organic and conventional conditions for 2 decades and diverges considerably genetically as a result. Don’t need AI to predict that. Perhaps more surprisingly, analysis suggests organic-adapted populations need to be selected for root traits to catch up in yield.
- Natural selection drives emergent genetic homogeneity in a century-scale experiment with barley. What is it with barley breeding and long-term experiments? This one shows that a hundred years of natural selection has massively narrowed genetic diversity. Why aren’t there long-term wheat experiments? Or are there?
- Association study of crude seed protein and fat concentration in a USDA pea diversity panel. Really high protein peas are possible. No word on whether kids will like them any better. Let’s check again in a hundred years?
- Telomere-to-telomere Citrullus super-pangenome provides direction for watermelon breeding. Forget sweetness and disease resistance, maybe one of these wild species will help us grasp the holy grail of seedlessness. Wait, let me check on the whole cost-benefit thing for this.
- An indigenous germplasm of Brassica rapa var. yellow NRCPB rapa 8 enhanced resynthesis of Brassica juncea without in vitro intervention. Sort of like that wheat D genome thing, but for mustard. I do wonder why we don’t try crop re-synthesis a lot more.
- Special issue: Tropical roots, tubers and bananas: New breeding tools and methods to meet consumer preferences. Why involving farmers in all of the above could be a good idea.

- The authors of book “Moving Crops and the Scales of History” have been awarded the Edelstein Prize 2024 for their work to “redefine historical inquiry based on the ‘cropscape’: the assemblage of people, places, creatures, technologies, and other elements that form around a crop.” Let’s see how many cropscapes we can come up with today.
- Here’s one. The Ecuador cacao genebank gets some much-needed help.
- Digging into Nigerian yams. And another.
- Castle Hex has a programme on Lima beans on 7-8 September. Sounds like fun.
- What if you can’t work out what the crops are, though? As in Mesopotamian recipe books, for example.
- The community seed banks of Nepal have a new website. Good news for those Nepalese cropscapes.
- A new project is testing RNA integrity number (RIN) as a metric of seed aging for a bunch of rare wild plants. One day maybe community seed banks will be using it.
- China has inventoried its agricultural germplasm. Will it be applying RIN next?
- The French are using bandes dessinées to teach about cryopreservation of animal genetic resources. Livestockscapes?
- Some drylands are getting greener and some people think that’s a problem. Always something.
Not Your Usual Potatoes
Jeremy’s latest newsletter discusses a very humble wild potato species, which we have actually blogged about here on a number of previous occasions. Do subscribe, there’s other cool stuff in there.
Indigenous people in the southwest of North America had more of a hand in crop domestication than is often thought, according to a new paper on the Four Corners potato, Solanum jamesii. So much so, according to the press release I read, that the results “support the [uncited] assertion that the tuber is a ‘lost sister,’ joining maize, beans and squash—commonly known as the three sisters—as a staple of crops ingeniously grown across the arid landscape”.
The release explains that populations of Four Corners potato, found, naturally enough, in the areas where Arizona, Utah, Colorado and New Mexico meet, fall into two distinct types. Some — archeological populations — grow within 300 metres of an archaeological site and are relatively small. The rest are non-archaeological and widely spread throughout the species’ range. Sampling the DNA of both types, the researchers discovered much more diversity in the non-archaeological populations than in those associated with settlements, which suggests domestication by local people.
Researchers were also able to show that specific archaeological populations were most like non-archaeological populations quite some distance away, which means that transport networks among the indigenous people were well developed. Settlement sites in the southwest of Utah were around 500 km from the nearest natural populations from which they might have been derived.
S. jamesii contains double the protein, calcium, magnesium, and iron of more familiar potatoes (S. tuberosum). The archeological populations were, however, not within the species’ central range, where the wild populations are much larger and more productive. So did people transport and grow the tubers simply to have a nourishing source of food close at hand in winter? That would be cultivation. Or were they, as seems likely, also actively selecting for things like taste, size and frost tolerance, which would put them well on the way to domestication? More detailed DNA might studies provide an answer.
A further thought. Four Corners potato, which is still grown by some Diné people (and probably others), copes well with drought and heat. Might it also have a wider market?
Nibbles: SeedLinked, Heritage Seed Library, HarvestPlus, Enset, EBI, Saharan/Sahelian flora, Pollen, Food & climate, Food prices, Moonraker, Svalbard eats, Devex does seeds, CGRFA ABS survey
- SeedLinked: an app to source cool vegetable seeds. And more.
- Want to become a variety champion for the Heritage Seed Library? Where’s the app though?
- A compendium of evidence on the efficacy of biofortification from HarvestPlus. Jeremy surely available for comment?
- Kew celebrates efficacy of enset conservation in Ethiopia.
- Not sure if the Ethiopia Biodiversity Institute is in on that celebration.
- Some of Ethiopia is Sahelian, no? Anyway, here’s a nice piece on the forgotten, but important plants from that neck of the woods.
- We should all celebrate pollen banking much more.
- Celebrity chef worried about the effect of climate change on food.
- Including food prices. I dunno, maybe pollen banking will help.
- Or maybe even a lunar repository.
- Speaking of food prices, I bet this Svalbard restaurant is not cheap. Maybe there’s a nice view of the Seed Vault though. Who needs the moon?
- The latest Devex newsletter has lots of stuff on food prices and prizes and (non-lunar) seed vaults.
- Do you use any of the above for research and development? The FAO Commission on Genetic Resources for Food and Agriculture would like to hear from you.
Nibbles: Forest seed collecting, Colombian maize, Türkiye & China genebanks, Community seedbank trifecta, Wheat breeding, Rice breeding, Bean INCREASE, WorldVeg regen, UK apples, Rangeland management
- How to collect forestry seeds.
- Whole bunch of new maize races collected in Colombia.
- The Türkiye national genebank in the news. Lots of collecting there. Though maybe not as much as in this genebank in China.
- But small communities need genebanks too. Here’s an example from Ghana. And another from India. And a final one from the Solomon Islands.
- Need to use the stuff in genebanks though. Here’s how they do it in the UK. And in Bangladesh. And in Europe with the INCREASE project, which has just won a prize for citizen science. And in Taiwan. Sort of citizen science too.
- Collecting apples in the UK. Funny, the canonical lost-British-apple story appears on the BBC in the autumn usually. Kinda citizen science.
- Or we could do in situ conservation, as in this South African example… Just kidding, we all know it’s not either/or. Right? Probably a good idea to collect seeds is what I’m saying. Could even do it through citizen science.
