- A chickpea genetic variation map based on the sequencing of 3,366 genomes. Where the good and the bad alleles are. Even The Economist is impressed.
- Crop Wild Relatives Crosses: Multi-Location Assessment in Durum Wheat, Barley, and Lentil. There are lots of good alleles in the wild relatives.
- The arches and spandrels of maize domestication, adaptation, and improvement. Some alleles are good by accident, and that’s ok.
- Malting Quality of ICARDA Elite Winter Barley (Hordeum vulgare L.) Germplasm Grown in Moroccan Middle Atlas. Here are some alleles for good beer.
- High molecular weight glutenin gene diversity in Aegilops tauschii demonstrates unique origin of superior wheat quality. And here are some alleles for good gluten. In a wild relative from unexpected place, as it turns out. More in the press release.
- Genetic resources of bottle gourd (Lagenaria siceraria (Molina) Standl.] and citron watermelon (Citrullus lanatus var. citroides (L.H. Bailey) Mansf. ex Greb.): implications for genetic improvement, product development and commercialization: a review. Not just good as rootstocks, and lots of alleles to play with.
- Coconut genome assembly enables evolutionary analysis of palms and highlights signaling pathways involved in salt tolerance. Looks like coconut might have lost a lot of good alleles at the end of the Pleistocene glaciations.
- High-quality reference genome sequences of two coconut cultivars provide insights into evolution of monocot chromosomes and differentiation of fiber content and plant height. The same gene controls height in coconuts as in maize and rice.
- Enhancing the searchability, breeding utility, and efficient management of germplasm accessions in the USDA−ARS rice collection. And now you can look for rice germplasm with the good height allele you want.
- History and impact of a bean (Phaseolus spp., Leguminosae, Phaseoleae) collection. Hopefully will be able to do the same for this bean collection soon.
- Integrating Genomic and Phenomic Approaches to Support Plant Genetic Resources Conservation and Use. The above, summarized.
- Gene Bank Collection Strategies Based Upon Geographic and Environmental Indicators for Beef Breeds in the United States of America. The above, plus environmental data, for cattle.
- History of Global Germplasm Conservation System. The above, writ large.

- Development of the first axillary in vitro shoot multiplication protocol for coconut palms. Cloning the tree of life, really fast.
- Frequent germplasm exchanges drive the high genetic diversity of Chinese-cultivated common apricot germplasm. Looking forward to the same being said about coconut.
- Crop diversity effects on temporal agricultural production stability across European regions. The effects are good.
- Are agricultural sustainability and resilience complementary notions? Evidence from the North European agriculture. They are indeed, but what about stability though?
- Seasonal variability of women’s dietary diversity and food provisioning: a cohort study in rural Burkina Faso. Do Europe now.
- The “Sweet Spot” in the Middle: Why Do Mid-Scale Farms Adopt Diversification Practices at Higher Rates? Spoiler alert: it’s got less to do with farm size than with access to resources and markets. At least for Californian lettuce farmers.
- Politics of seeds in Ethiopia’s agricultural transformation: pathways to seed system development. The Ethiopian seed system needs diversification just as much as Californian lettuce farmers.
- Biocultural Diversity for Food System Transformation Under Global Environmental Change. What we all need is biocultural diversity.
- Harnessing the diversity of small-scale actors is key to the future of aquatic food systems. Yes, all of us, whether in mountains or by the sea.
- Combatting global grassland degradation. It may be stretching a point, but biocultural diversity may also be a useful lens through which to look at grassland restoration and sustainable management. But then I would say that.
- Supporting wild pollinators in agricultural landscapes through targeted legume mixtures. Yeah, let’s not forget the pollinators while we’re at it.
Nibbles: Pasta al forno, Polynesian dispersal, Ryan Phelan talk
- More evidence that some food staples are going to be in trouble.
- Samoa to Rapa Nui in 400 years. But the Americas before that? Mash up with banana, taro and sweet potato next.
- TED talk on genetic rescue.
Nibbles: Eat This Newsletter, Basmati, DSI, NBPGR collecting, Ganja page
- Jeremy’s latest newsletter covers in more depth things we just Nibbled here, including perry and ancient bananas, plus much other stuff. We talked about “wild rice” here a couple of times.
- As for actual rice, the controversy between India and Pakistan about the origin of Basmati just got a bit more complicated. Could it in fact have come from Afghanistan?
- Maybe everyone should listen to Dr Amber Scholz’s ideas about ABS.
- Meanwhile, India’s National Bureau of Plant Genetic Resources regional centre in Kumaon has been busy collecting germplasm. No word on whether that includes rice, Basmati or otherwise.
- Pretty cool way of presenting accession data, courtesy of Mystery Haze. I wonder where that’s from originally.

- A global database of diversified farming effects on biodiversity and yield. Always good to have the data.
- Dietary agrobiodiversity for improved nutrition and health outcomes within a transitioning indigenous Solomon Island food system. Maybe we should have a database of diversified farming effects on health and nutrition too?
- Exploring ‘beyond-food’ opportunities for biocultural conservation in urban forest gardens. Always good to have more trees.
- Community seed network in an era of climate change: dynamics of maize diversity in Yucatán, Mexico. Always good to have landraces. And neighbours.
- Microbe-dependent heterosis in maize. Maize hybrids need microbes.
- Assessment of genetic diversity and population structure of oil palm (Elaeis guineensis Jacq.) field genebank: A step towards molecular-assisted germplasm conservation. 30% seems a lot for a core collection. But it’s good to have the data.
- Sources of resistance to Pseudocercospora fijiensis, the cause of black Sigatoka in banana. 11 resistant accessions out of 95 seems pretty good, on the other hand.
- GWAS unveils features between early- and late-flowering pearl millets. Based on a national-level core collection in Senegal. Presumably this will scale?
- Germplasm Collection, Genetic Resources, and Gene Pools in Alfalfa. Lots of work has been done. More work is needed on the wild relatives though.
- Assessment and modeling using machine learning of resistance to scald (Rhynchosporium commune) in two specific barley genetic resources subsets. Fancy maths helps to identify the barley genebank accessions you really need.
- Strategic malting barley improvement for craft brewers through consumer sensory evaluation of malt and beer. More fancy maths, this time applied to a hedonic data in the service of beer. Germplasm evaluation we can all get behind. No FIGS, alas.
- Large-scale whole-genome resequencing unravels the domestication history of Cannabis sativa. 4 genetic groups: primordial (located in China, not Central Asia, and going back 12,000 years), 2 medicinal, 1 fibre. Now for the hedonic evaluation.
- The Origins of the Apple in Central Asia. Probably domesticated to cope with the munchies.
- Genetic Divergence and Population Structure in Weedy and Cultivated Broomcorn Millets (Panicum miliaceum L.) Revealed by Specific-Locus Amplified Fragment Sequencing (SLAF-Seq). There are interesting genetic differences between wild and feral forms, and between eastern and central-western cultivated forms. The Silk Road trifecta.
- Global range expansion history of pepper (Capsicum spp.) revealed by over 10,000 genebank accessions. Spoke too soon. The Silk Road had a role in pepper movement too. Among other trade routes. Interesting, and unsurprising, that genes for pungency show distinct geographic patterns.
- Genomic evidence supports an independent history of Levantine and Eurasian grapevines. First domestication in the Caucasus, and then in the Levant, but not clear if from local sources. No word on hedonic evaluation.
- Genotyping-By-Sequencing diversity analysis of international Vanilla collections uncovers hidden diversity and enables plant improvement. Belize seems to be a real hotspot. The Silk Road not involved.
