Crowdsourcing variety evaluation data
Jacob van Etten has a new paper out which uses information on variety performance crowdsourced from farmers to support climate change adaptation. He’s been tweeting about it. A lot. Here’s a taste:
Yesterday I promised to write some tweets about our recent article in @PNASNews. A nerdy thread on technical details first! We used a cool model to analyze farmers' crop variety evaluation and test if seasonal climate could explain differences. https://t.co/4DD7eSVq1l pic.twitter.com/xF9MSCiJ4I

The threads are unrolled here, here and here if you prefer to stay away from Twitter.
We’re hoping Jacob will answer any questions you might have on the paper right here on the blog in the near future. If you do have any questions, tweet them at him, or leave them here.
And let me take this opportunity of linking to this “field guide” to methods for making new crop diversity available to farmers which sort of sets Jacob’s paper in context.
Brainfood: Improvement recapitulates domestication, Functional variation, Intensification, Gender & nutrition, Collaboration double, Losses, AgRenSeq , Crocus domestication, Saffron evolution, Mascarene CWR, Mexican CWR, ABS, Sweet cocoa, Tasty fruits, Baobab diversity
- How can developmental biology help feed a growing population? By figuring out how domestication hacked developmental processes.
- Distinct characteristics of genes associated with phenome-wide variation in maize (Zea mays). Analyzing a lot of traits at a time identifies a different set of phenotypically causal genes than more conventional single-trait approaches. What it all means in practice I have no idea, you tell me.
- Sunflower pan-genome analysis shows that hybridization altered gene content and disease resistance. Not only is one trait not enough, one genome is not enough.
- Agriculturally productive yet biodiverse: human benefits and conservation values along a forest-agriculture gradient in Southern Ethiopia. Depends what you mean by productive.
- Does providing agricultural and nutrition information to both men and women improve household food security? Evidence from Malawi. Yes.
- Principles of effective collaboration in agricultural development and research for impact. Learn from the birds.
- Opening the dialogue: Research networks between high‐ and low‐income countries further understanding of global agro‐climatic challenges. See above. Maybe.
- The global burden of pathogens and pests on major food crops. About 20%. We talked about this…
- Resistance gene cloning from a wild crop relative by sequence capture and association genetics. A new way to reduce the above, using crop wild relatives.
- Adding color to a century‐old enigma: multi‐color chromosome identification unravels the autotriploid nature of saffron (Crocus sativus) as a hybrid of wild Crocus cartwrightianus cytotypes. Which means you can now re-synthesize it.
- Crop wild relative diversity and conservation planning in two isolated oceanic islands of a biodiversity hotspot (Mauritius and Rodrigues). Basically coffee.
- Diversity and conservation priorities of crop wild relatives in Mexico. Over 300 species, but not coffee.
- Benefit sharing mechanisms for agricultural genetic diversity use and on-farm conservation. Profit-sharing is better for conservation than technology transfer.
- Are Cocoa Farmers in Trinidad Happy? Exploring Factors Affecting their Happiness. Well, those whose main crop was not cacao are happier, which must say something.
- Edible fruits from Brazilian biodiversity: A review on their sensorial characteristics versus bioactivity as tool to select research. Eat Anacardium occidentale, Passiflora edulis and Acrocomia aculeata to be happiest. Seems very unadventurous, though.
- Genetic differentiation in leaf phenology among natural populations of Adansonia digitata L. follows climatic clines. Anyone going to do this for all those Brazilian fruits?
Brainfood: Gene mining, Using genebanks, Wild tomato hybrids, Domestication genes, Intensification, Cicer photoperiod, China ABS, Hybridization, Conservation vs livelihoods, Flax evolution, Clean cassava
- Seeing nature as a ‘universal store of genes’: How biological diversity became ‘genetic resources’, 1890–1940. “Beyond the space-time of Neo-mendelian and Morganian laboratory genetics, genes became understood though a geographical gaze at a planetary scale.”
- Harnessing the potential of germplasm collections. Start with diverse germplasm, then edit in domestication genes.
- Spatial proximity determines post-speciation introgression in Solanum. But said introgression is not that important, in the grand evolutionary scheme of things, at least for these wild tomatoes.
- Understanding Grass Domestication through Maize Mutants. It’s not straightforward, because domestication genes work differently in maize, because of differences in regulation.
- May innovation on plant varieties share agricultural land with nature, or spare land for it? It may do both, under certain conditions. If I understand the economics jargon correctly.
- Photoperiod Response of Annual Wild Cicer Species and Cultivated Chickpea on Phenology, Growth, and Yield Traits. They need 15-18h to flower.
- China’s Legal Issues in the Access and Benefit-sharing of the Genetic Resources. …need addressing urgently.
- Insights from genomes into the evolutionary importance and prevalence of hybridization in nature. It’s everywhere, but whether it’s adaptive is hard to prove. One crop example: common bean.
- Incorporating basic needs to reconcile poverty and ecosystem services. Complicated but workable methodology to identify the win-win solution space.
- Flax latitudinal adaptation at LuTFL1 altered architecture and promoted fiber production. Flax became a fibre crop when it was carried north into Europe as a result of adaptation to higher latitudes, including by introgression from local wild species.
- A method for generating virus-free cassava plants to combat viral disease epidemics in Africa. Chemo- and thermotherapy in tissue culture.
