- Average returns on agricultural R&D investment is 100%, says CGIAR.
- I wonder how many from this list of the most innovative plant varieties of 2020 can trace back to some CGIAR product. Or genebank.
- Which sweet potato varieties do consumers actually like in PNG?
- Cool visualizations of the relationships between Mexican crops and foods.
- One village, 100 mangoes. Visualize that.
- Don’t blame high food prices on war. Entirely, anyway.
- Lactase persistence is not due to the benefits of drinking milk. Entirely, anyway.
- A whole bunch of tools to help select trees to plant in Europe. The entirely correct URL for the climate matching tool is this one though.
- Why worry about any of that when you can have sea gardens, though?

- The genomic signature of wild-to-crop introgression during the domestication of scarlet runner bean (Phaseolus coccineus L.). The wild Mexican genepool is helping to counteract the effects of the domestication bottleneck.
- Genetic variation in wild and cultivated Arabica coffee (Coffea arabica L.): Evolutionary origin, global distribution, and its effect on fungal disease incidence in Southwest Ethiopia. Domesticated disease-resistant cultivars are threatening the genetic integrity of the wild genepool. You win some, you lose some.
- Uncovering haplotype diversity in cultivated Mexican vanilla species. Plenty of evidence of past hybridization events in cultivated vanilla in Mexico. Maybe it can swap stories with scarlet runner bean.
- Six-rowed wild-growing barleys are hybrids of diverse origins. In the case of barley, the wild-cultivated hybrids even got a separate Latin binomial.
- Portrait of a genus: genome sequencing reveals evidence of adaptive variation in Zea. Lots of variation in interesting adaptive traits in the wild relatives of maize. Did they, or will they, make their way into the crop, I wonder?
- An adaptive teosinte mexicana introgression modulates phosphatidylcholine levels and is associated with maize flowering time. This one did.
- A highly conserved core bacterial microbiota with nitrogen-fixation capacity inhabits the xylem sap in maize plants. Its wild relatives are not the only wild organisms maize benefits from.
- Phenomic data-facilitated rust and senescence prediction in maize using machine learning algorithms. Drones and fancy maths can be used to predict and document southern rust infection in maize. Maybe in wild relatives too one day, who knows.
- A Solanum lycopersicoides reference genome facilitates insights into tomato specialized metabolism and immunity. A tomato wild relative has a gene for resistance to bacterial speck disease, so of course they had to sequence its genome.
- Genetic gains in potato breeding as measured by field testing of cultivars released during the last 200 years in the Nordic Region of Europe. Genetic gains for yield (measured in non-target environments) were not that great and contributed about half of productivity gains. Results for other traits were even worse, mainly because of stringent market demands. So no chance of using wild relatives I suppose.
- Genotypic Response and Selection of Potato Germplasm Under Heat Stress. Not so fast…
- Dataset of historic and modern bread and durum wheat cultivar performance under conventional and reduced tillage with full and reduced irrigation. I wonder to what extent wild relatives contributed to the differences.
- Assessing returns to research investments in rice varietal development: Evidence from the Philippines and Bangladesh. Net returns from collaboration in rice breeding between IRRI and national partners are still strong in the Philippines and Bangladesh, but declining, and faster in the former than the latter. Plenty of genes from wild relatives in IRRI lines of course. Maybe there could be more?
Podcasting agricultural biodiversity
Talking of agrobiodiversity-themed podcasts 1, there’s a fun dip into (some of the) history of the tomato over at Historically Thinking. Meanwhile, at Eat This Podcast, Jeremy has embarked on a monumental romp 2 through the role of wheat in world history. Pizza, anyone?

- The quest for red rice beer: transregional interactions and development of competitive feasting in Neolithic China. In the 4th millennium BCE, in China, people brewed a sacred red beer in vats called dakougang using rice, millet, Job’s tears, wheat and snake gourd root.
- The biocultural origins and dispersal of domestic chickens. The earliest domesticated chickens are found 1650-1250 BCE in central Thailand and were attracted by stored rice and millet. No word on the role of beer.
- Performance, Economics and Potential Impact of Perennial Rice PR23 Relative to Annual Rice Cultivars at Multiple Locations in Yunnan Province of China. But does it make decent beer and attract chickens?
- Genomic prediction of zinc-biofortification potential in rice gene bank accessions. Check out in particular the aus subspecies. No word on whether the resulting beer and chickens are also high in zinc.
- Do ancient wheats contain less gluten than modern bread wheat, in favour of better health? More to the point, do they make better beer?
- Evidence for two domestication lineages supporting a middle-eastern origin for Brassica oleracea crops from diversified kale populations. Chickens not involved at all.
- Genome evolution and diversity of wild and cultivated potatoes. Propagation by tubers had a big effect on the cultivated potato genome compared to propagation by seed. And no, I’m not going to get into the whole chickens-in-South-America controversy right now, but you can google it.
- The genomics of linkage drag in sunflower. Introgression from wild relatives has been good for some things, bad for others, but in general pre-breeders should stick to the primary genepool. And watch out for chickens.
- From horticulture to agriculture: New data on farming practices in Late Chalcolithic western Anatolia. While domestic units were small and agriculture extensive, cooperation was widespread and inequality low. Then those Bronze Age elites got chickens…
Nibbles: Gulf garden, Lettuce evaluation, Jordanian olive, Kenyan seeds, Hybrid animals, FAOSTAT news
- Qatari botanic garden is providing training in food security, and more. Good for them.
- The European Evaluation Network’s lettuce boffins have themselves a meeting. Pretty amazing this made it to FreshPlaza, and with that headline.
- The Jordan Times pretty much mangles what is a perfectly nice, though inevitably nuanced, story about the genetic depth of Jordan’s olives.
- In Kenya’s seed system, whatever is not forbidden in proposed new legislation…may not be enough.
- Conservation through hybridization.
- FAOSTAT now has a bit that gives you access to national agricultural census data. Which sounds quite important but give us a few days to check it.
