- The recent evolutionary rescue of a staple crop depended on over half a century of global germplasm exchange. Sorghum in Haiti was saved from pest by breeders mixing up material from all over the place.
- Does crop genetic diversity support positive biodiversity effects under experimental drought? Not straightforwardly, at least for barley cultivar mixtures in pots.
- A Nutrition-Sensitive Agroecology Intervention in Rural Tanzania Increases Children’s Dietary Diversity and Household Food Security But Does Not Change Child Anthropometry: Results from a Cluster-Randomized Trial. Well at least it’s more straightforward than the above.
- The tepary bean genome provides insight into evolution and domestication under heat stress. Better heat adaptation than common bean, but less disease and pest resistance.
- The international political process around Digital Sequence Information under the Convention on Biological Diversity and the 2018–2020 intersessional period. Can’t take the above for granted.
- Practical consequences of digital sequence information (DSI) definitions and access and benefit‐sharing scenarios from a plant genebank’s perspective. Genebanks trying not to take the above for granted.
- Cryopreservation of Woody Crops: The Avocado Case. There’s been a breakthrough in shoot tip cryopreservation.
- Using Regulatory Flexibility to Address Market Informality in Seed Systems: A Global Study. Regulatory flexibility would certainly be a breakthrough for linking formal and informal seed systems. And, incidentally, not bad for DSI either.
- A recipe development process model designed to support a crop’s sensory qualities. When you want to make a recipe for a new ingredient (crop or heirloom variety), start with what makes the ingredient special, not with what might make the end-product special.
- Genetic diversity and population structure analysis in a large collection of white clover (Trifolium repens L.) germplasm worldwide. Native and introduced populations are genetically differentiated.
- Limited haplotype diversity underlies polygenic trait architecture across 70 years of wheat breeding. Crunch time for UK wheat breeders: continue shuffling within the existing diversity, or expand it?
- Molecular Parallelism Underlies Convergent Highland Adaptation of Maize Landraces. Adaptation to high altitude from the SW US to the Andes was due to wild genes from the Mexican highlands.
Another career in crop diversity
Dr Mike Jackson is retired now, after a long and very impactful career in plant genetic resources conservation. But he writes about that career, and a lot more besides, on his blog. And now there’s also a nice conversation with him on the Plant Breeding Stories podcast, focusing on his work on potato and rice.
Tom Payne on a career conserving and using wheat diversity
It’s really transition time at the CIMMYT genebank. Denise Costich retired, and Terry Molnar took over her role running the maize part of the operation. And very soon Tom Payne will also retire, from leading the wheat genebank. Check out this nice Q&A with Tom, and join me in wishing him all the best on the next chapter of his life.

Nibbles: Cryo genebanks, In situ network, Biodiversity fund, Swiss grape, Coffee history, Wild plant use, Plant breeding impact
- Panel discussion on cryopreservation in genebanks on 25 June, save the date!
- Forget cryo, what about a network of European network for the conservation and sustainable use of plant genetic resources, in cultivation and in the wild? See who is interested. And express interest yourself.
- Germans launch Legacy Landscape Fund for biodiversity hotspots. European in situ PGR conservation network unavailable for comment. Let alone cryo genebanks.
- I wonder if that European on-farm conservation network will include the Completer grape, ideally in a monastery.
- Decolonizing coffee. Somebody want to write about religion and crops?
- Using wild plants in south and southeast Asia. Maybe they need a network too.
- Plant breeders say plant breeding is really important.
The value of seeds
Douglas Gollin, Professor of Development Economics at the University of Oxford will speak about genebanks tomorrow, and you really mustn’t miss it. The talk’s title? “In Praise of Seed Morgues.” See what I mean?
LATER: The recording is on the GROW webpage. And here’s a spoiler…
