- Landrace in situ (on-farm) conservation: European Union achievements. Lots of organizations and farmers are conserving landraces in Europe, in lots of ways, and pretty successfully, but the most sustainable way to do so would be to decrease barriers to their marketing, in particular in the context of organic agriculture.
- An assessment of the implementation of the EU policy for conservation varieties from 2009 to 2023 and its relationship to Geographical Indications. Few European GIs use conservation varieties (i.e. landraces), but this should, and probably will, change.
- New citizen science initiative enhances flowering onset predictions for fruit trees in Great Britain. Imagine doing this for European landraces.
- Genetic markers identify duplicates in Nordic potato collections. Ooops, some alleged landraces in European genebanks turn out to be old improved varieties.
- Curation of historical phenotypic wheat data from the Czech Genebank for research and breeding. You need data on all those landraces if people are going to use them. Citizen scientists might help, I guess.
- Trait-customized sampling of core collections from a winter wheat genebank collection supports association studies. But you need to use that data to create subsets first, and you can do that in lots of different ways, for different purposes: let the German genebank show you how.
- Collecting Mediterranean wild species of the Brassica oleracea group (Brassica sect. Brassica). Even in Europe some gap-filling collecting is still necessary.
- A comparison of Chinese wild and cultivar soybean with European soybean collections on genetic diversity by Genome-Wide Scan. Even breeders in the soybean center of diversity might find material from Europe’s genebanks useful.
- Can Sustainability and Biodiversity Conservation Save Native Goat Breeds? The Situation in Campania Region (Southern Italy) between History and Regional Policy Interventions. Conservation livestock breeds, anyone?

- Why we need crop wild relatives.
- No, really, we need crop wild relatives.
- The banana is in trouble.
- Which is why we need to conserve banana wild relatives and landraces.
- Lots of wild relatives are conserved in the IRRI genebank mentioned in this Guardian article on breeding low glycemic index and high protein rice. Some of them may even have been used in this work. May look that up one day.
- I doubt that IITA used wild relatives in breeding these high quality cassava varieties, but there’s always a first time, and there may even be some in its genebank. I should probably look but I don’t have time for this rabbit hole today.
- And livestock get conserved in genebanks too, though not as much as crops. I’m really not sure how many livestock wild relatives are in the world’s genebanks, but my guess is not many.
- Farmers conserve crop (and livestock) diversity too, of course. And sometimes even their wild relatives.
- It’s amazing what can be done from space to figure out what farmers are growing. This is an example of sunflower in Ukraine, but one day we’ll even be able to locate crop wild relatives, I’m sure.
- To finish off, a reminder that we need conserved seed of wild species for more than just breeding: restoration too.

- Never thought I’d see the Svalbard Global Seed Vault in Psychology Today, yet here we are.
- The Pacific’s regional genebank is set for more work on lesser-known crops. Too bad most of them won’t be able to go to Svalbard.
- How to make a genebank beautiful as well as sustainable.
- Australia has a rice genebank. For some reason.
- Bangladesh gets a new genebank. Could have sworn it already had one.
- Mutants need a genebank too.
- And inoculants.
- Community-level genebanks have their place too. Though probably not for mutants.
- As long as the farmers get a benefit, of course.
- Tricot is a good way of evaluating all that stuff in genebanks.
- But you should also genotype it.
- Why bother with all this? Andreas Volz has a nice explanation.
- Genetic diversity is all very good, but don’t forget to intercrop.
- Which includes agroforestry.
- For a more varied diet.
- And a better world economy.
- And a more sustainable food system.

- 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.
