- Detection of banana plants and their major diseases through aerial images and machine learning methods: A case study in DR Congo and Republic of Benin. Yeah but can you apply it to collecting the wild relatives?
- Genetic and genomic resources for finger millet improvement: opportunities for advancing climate-smart agriculture. No way this can be called neglected any longer. But is it still under-utilized?

- Pleistocene climate changes, and not agricultural spread, accounts for range expansion and admixture in the dominant grassland species Lolium perenne L. Lots more unused diversity out there. For now.
- IUCN Red List and the value of integrating genetics. Applying some genetic rules of thumb make some endangered species even more so.

Nibbles: Robin Graham RIP, Fred Bliss award, Seed production, Chile spuds, Indian goats, Ancient bread, Horner Bier, Cheap food, Vigna, Singing dog, Fungal diversity
- Remembering Robin Graham, prophet of biofortification.
- Honouring plant breeder supreme Fred Blisss.
- Need to produce seed of all those new varieties that breeders come up with.
- And save the stuff they will replace: The Economist does the potatoes of Chiloé.
- Hey, it’s not just about the crops: conserving goats on farm in India.
- The experimental archaeology of bread thrives under corona. And if you were intrigued by the potato detoxification reference, find the details on Bill Schindler’s website. And not only bread and potatoes, also beer…
- Like Mozart’s oat beer? Which was apparently killed off by lager back in Austria but is now available in Denver.
- Food shouldn’t be cheap, it should be affordable, and not only for those who consume it. Ancient Egyptian bread will be exempted.
- No way Kenyan coffee can be described as cheap. h/t Jeremy’s newsletter: have you subscribed yet?
- I don’t know how cheap mungbean is in Myanmar, but it seems to be very valuable.
- The PNG singing dog is not extinct in the wild after all? Priceless.
- Combination of key and photo guide to the identification of European fungi. Worth its weight in truffles. Source.

- Seed security response during COVID-19: building on evidence and orienting to the future. First and foremost, support farmers save their seeds.
- Blended finance for agriculture: exploring the constraints and possibilities of combining financial instruments for sustainable transitions. How about supporting farmers save their seeds?
- Dynamic conservation of genetic resources: Rematriation of the maize landrace Jala. Genebanks helping farmers save their seeds.
- Molecular Parallelism Underlies Convergent Highland Adaptation of Maize Landraces. Early farmers saving their maize seeds in the Mexican highlands eventually helped out farmers in the Andean highlands. With GIF goodness.
- Open access to genetic sequence data maximizes value to scientists, farmers, and society. How will it help farmers save their seeds?
- Applying Knowledge of Southern Seed Savers to Community-Based Agricultural Biodiversity Conservation Practice. The people saving and swapping seeds in the Ozarks respond to films, need how-to manuals, and could be a tad more diverse. I suspect this is not just true in Arkansas.
- Characterization of wheat germplasm conserved in the Indian National Genebank and establishment of a composite core collection. Farmers trying to save their seeds rejoice.
- Heritable epigenetic diversity for conservation and utilization of epigenetic germplasm resources of clonal East African Highland banana (EAHB) accessions. Hey, it’s not just seeds. Methylation patterns follow geography but not morphology in a genetically uniform group of vegetatively propagated cultivars.
- Blind spots in global soil biodiversity and ecosystem function research. Not now, soil biodiversity, I’m too busy dealing with seeds.
- Narrow genetic base shapes population structure and linkage disequilibrium in an industrial oilseed crop, Brassica carinata A. Braun. Landraces of Ethiopian mustard and improved lines cluster in separate groups, but overall diversity is low. Not enough seeds saved, perhaps?
- High-Throughput Genome-Wide Genotyping To Optimize the Use of Natural Genetic Resources in the Grassland Species Perennial Ryegrass (Lolium perenne L.). Only possible because of saved seeds.
- Presence of resveratrol in wild Arachis species adds new value to this overlooked genetic resource. I hope we’ve saved enough seeds.
- Main Challenges and Actions Needed to Improve Conservation and Sustainable Use of Our Crop Wild Relatives. It’s quite difficult — and insufficient — to save the seeds of wild species, but we should do it nevertheless.
- Influence of diversity and intensification level on vulnerability, resilience and robustness of agricultural systems. Why we should all save seeds.
Nibbles: Yunnan mushrooms, Torres Is bananas, Boxgrove, Gluten trends, Apple rootstocks, USDA horticulture job
- There’s a sort of mycological culinary hotspot in Yunnan… Yeah, I thought that too.
- Signs found of old banana cultivation in Australia. Well, kinda. As in not as old as in PNG, and not mainland Australia.
- Really, really old horse butchery site in southern England excavated. When the Brits ate horses. Well, kinda.
- New wheat is pretty much like old wheat, gluten-wise at least.
- Breeding better apple rootstocks at USDA. A hitherto somewhat neglected aspect of apple genetic conservation and improvement.
- Speaking of USDA, here’s another job.

- Maize long-term genetic progress explains current dominance over sorghum in Argentina. Follow the money.
- Phenotypic and physiological responses to salt exposure in Sorghum reveal diversity among domesticated landraces. Salinity tolerance was acquired early but then lost in some geographic regions where it wasn’t needed. See what happens when you invest in a crop?
- Massive haplotypes underlie ecotypic differentiation in sunflowers. It’s the recombination-suppressing inversions, stupid.

- The earliest domestic cat on the Silk Road. Coincided with rapid urbanization in the 9th century.
- Native American gene flow into Polynesia predating Easter Island settlement. Yeah, but did Americans go west of their own accord or in Polynesian boats? And did they have sweetpotatoes with them? And cats?
- Genetic markers associated with seed longevity and vitamin E in diverse Aus rice varieties. 5 markers on 4 chromosomes.
- Biogeoinformatics for the management of Farm Animal Genetic Resources (FAnGR). Software for monitoring erosion and detecting locally adapted genotypes. Plus preserve traditional practices.
- Computing on Phenotypic Descriptions for Candidate Gene Discovery and Crop Improvement. Casually talk about a plant in the field –> fancy math –> the plant’s genotype.
- Data synthesis for crop variety evaluation. A review. Focus on ranking. Oh, to mash it up with the above.
- Scenarios for Global Aquaculture and Its Role in Human Nutrition. For aquaculture to contribute to nutrition it needs enabling trade and economic policies. Well I never.
