- Strategic use of Iranian bread wheat landrace accessions for genetic improvement: Core set formulation and validation. Not much structure, but some accessions are good for multiple traits.
- Population studies of the wild tomato species Solanum chilense reveal geographically structured major gene-mediated pathogen resistance. Not all populations of a crop wild relatives will be equally useful in breeding.

- Exotic foods reveal contact between South Asia and the Near East during the second millennium BCE. Bronze Age Levantines ate bananas and soya, according to dental calculus. No word on coffee.
- Archaeological Central American maize genomes suggest ancient gene flow from South America. Pre-domesticated maize was taken to South America, where is was finished off away from introgression from pesky wild relatives, and then taken back home.
- Fruits of the Veld: Ecological and Socioeconomic Patterns of Natural Resource Use across South Africa. South Africans collect and eat a lot of wild fruits, but could plant and eat them more.
- Exploring the Biodiversity of Red Yeasts for In Vitro and In Vivo Phenotypes Relevant to Agri-Food-Related Processes. Which is interesting because they can delay food spoilage and also provide nutritional supplements. Though personally I’d prefer veld fruits.

- Couscous gets protected. Phew, ’cause it’s right on the verge of extinction, isn’t it.
- I hope tepary beans don’t become the next macadamia.
- Reviving old potatoes the Nordic way.

Nibbles: Benchmarking, Unintended consequences, Kenyan seeds, WFP, China genebank, Evolutionary plant breeding, Citrus, Maize, Lotus silk, Azolla, Spanish genebank
- How committed are 350 food companies to food system transformation? Well, take a wild guess…
- Mind you, transformation is tricky.
- A climate-smart seed system for Kenya? Would be transformative for sure.
- Great that WFP got the Nobel Peace Prize, but they’re only part of the food system picture.
- Another part is genebanks, as China recognizes.
- One way to use all that material in genebanks is through evolutionary plant breeding.
- Citrus: How it started. How it’s going. Meme alert.
- Maize was taken back to Mexico from South America in ancient times. And those early farmers really knew how to process it for maximum benefit, something we’re forgetting.
- A deep dive into lotus silk.
- An even deeper dive into Azolla-covered paddies.
- Esteban Hernández of the Andalusian genebank gets his 15 minutes.

- Tropical forage technologies can deliver multiple benefits in Sub-Saharan Africa. A meta-analysis. Including improved germplasm, which had on average 2.6 times higher herbage productivity than local controls.
- Effective population size remains a suitable, pragmatic indicator of genetic diversity for all species, including forest trees. Which is good because you can estimate it fairly easily. Well, kinda. It’s important because it’s one of the Genetic diversity targets and indicators proposed for the CBD post-2020 Global Biodiversity Framework.
- Exploring the genetic variability and diversity of pearl millet core collection germplasm for grain nutritional traits improvement. 15 of 212 accessions are good for multiple nutrients.
- Global Status of Sorghum Genetic Resources Conservation. The two biggest collections are updating their data.
- Genomic basis of geographical adaptation to soil nitrogen in rice. Rice lost high tillering in high N conditions, but can get it back to cope with low N conditions.
- The Economic Impact of Exchanging Breeding Material: Assessing Winter Wheat Production in Germany. It really pays for breeders to exchange material.
- Comparative analysis of the gene pool structure of Triticum aethiopicum wheat accessions conserved ex situ and recollected in fields after 85 years. Vavilov’s collections are more diverse.
- Evidence for Two Main Domestication Trajectories in Saccharomyces cerevisiae Linked to Distinct Bread-Making Processes. Being adapted for industrial and artisanal baking respectively.

- Long-distance dispersal of the beach strawberry, Fragaria chiloensis, from North America to Chile and Hawaii. For the birds.
- Genetic architecture of wild soybean (Glycine soja Sieb. and Zucc.) populations originating from different East Asian regions. At least 3 separate groups, and the collection stored in Korea is pretty representative.
- Supporting habitat conservation with automated change detection in Google Earth Engine. Fancy math can detect land use change quickly and accurately.
- Health Impacts of the Green Revolution: Evidence from 600,000 births across the Developing World. Modern varieties reduced infant mortality by 2.4–5.3 percentage points (from 18%), with stronger effects for male infants and among poor households. Why we do all of the above?
- Articulating the effect of food systems innovation on the Sustainable Development Goals. Yeah, not so fast…

- Perennial Staple Crops: Yields, Distribution, and Nutrition in the Global Food System. Most perennial staple crops are not as well known or widely grown as annual staple crops, but maybe should be.
- Determining appropriate interventions to mainstream nutritious orphan crops into African food systems. Look to the supply of seeds.
- Diversity and conservation of traditional African vegetables: Priorities for action. Focus on conserving diversity West Tropical Africa and southern Cameroon. And then look to the supply of seeds everywhere, presumably.
- The origins of agriculture: Intentions and consequences. Domestication happened pretty much all by itself, through co-evolution.
- The role of the microbiota in human genetic adaptation. Co-evolution happened with the gut microbiota as well as with plants.
- Genome analyses reveal the hybrid origin of the staple crop white Guinea yam (Dioscorea rotundata). Unclear if people were involved.
- Crop adaptation to climate change as a consequence of long‑term breeding. Better to focus on the slow but steady accumulation of small effects. By people, presumably.
- Trends of genetic changes uncovered by Env- and Eigen-GWAS in wheat and barley. Maybe you don’t even need to measure the results of those small effects.
- Genetic Diversity of Coffea arabica. We need to catalogue all germplasm collections, together with their marker profiles, and make material and data easily available. Easier said than done.
- Farmers’ social networks and the diffusion of modern crop varieties in India. Caste affects adoption of new varieties.
- From garden to store: local perspectives of changing food and nutrition security in a Pacific Island country. Those that have access to stores, and therefore enough food, don’t have a well balanced diet, and those that don’t have store have a better balanced diet but occasionally not enough food. No word on modern varieties.
- The role of the milpa in food and nutritional security in households of Ocotal Texizapan, Veracruz, Mexico. Who needs stores?
- Dilemmas of protection: decolonising the regulation of genetic resources as cultural heritage. But are the above natural or cultural resources?
- A meta-analysis contrasting active versus passive restoration practices in dryland agricultural ecosystems. Just add water.
- Soil biodiversity enhances the persistence of legumes under climate change. If you want to keep legumes, and thus diversity, in your vegetation under climate change, better maintain soil biodiversity. Or add water, presumably.
- Soil microbial legacy drives crop diversity advantage: linking ecological plant‐soil feedback with agricultural intercropping. Same as above, but for intercropping.
- Effect of high temperature drying on seed longevity of Bambara groundnut (Vigna subterranea) accessions. Initial drying at 45°C/35% RH for 8 days before moving to a more conventional 17°C/15% RH can be good for some accessions, but which?
