- 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?

Brainfood: Finger millet diversity, US wheat diversity, Enset diversity, Anglo Saxon diets, Agrobiodiversity index, Rangeland management, Butia groves, Cryotherapy, Bogia Syndrome, Niche models, Merino ancestors
- Scientific Selection – A Century of Increasing Crop Varietal Diversity in US Wheat. Whether you take into account the genetic relationship among varieties or not, breeding has been driving up wheat diversity in American fields. But anyone else think this is a bit of a straw man?
- Novel GBS-Based SNP Markers for Finger Millet and Their Use in Genetic Diversity Analyses. The Zimbabwean and Ethiopian landraces are different and should be crossed more to inject some diversity into improved varieties. You mean like they did for wheat in the US?
- On-Farm Diversity of Enset (Ensete ventricosum (Welw.) Cheesman) Landraces, Use, and the Associated Indigenous Knowledge in Adola Rede District, Guji Zone, Oromia, Ethiopia. No problem with diversity in enset, at least morphologically speaking.
- Food and Power in Early Medieval England: a lack of (isotopic) enrichment. Elite “Anglo-Saxon” males did not have a diet that was consistently higher in meat than anyone else at the time, so there. I wonder if any ever ate enset.
- Assessment of agrobiodiversity in the intensive agriculture: a case study of the Indo-Gangetic Plains of India. Could do with some more legumes.
- Community-based rangeland management in Namibia improves resource governance but not environmental and economic outcomes. Market incentives do not always work the way you think.
- The palm trees choose the places – Popular knowledge associated with the use and conservation of butiá (Butia spp.). No word on market incentives.
- Shoot tip cryotherapy for plant pathogen eradication. Especially good if combined with thermotherapy or chemotherapy. May even work on enset, for all I know.
- The phytoplasma associated with Bogia coconut syndrome in Papua New Guinea is a new phytoplasma in the group of the lethal yellowing syndromes (LYTS) of coconut and other palms. Yeah but will cryotherapy work?
- Implementation of species distribution models in Google Earth Engine. Shhh, or everyone will want to do it, and then where will we be.

Brainfood: Green Revolution narratives, Soybean diversity, Wild barley diversity, Maize and bean breeding, Rice breeding, Apple pedigrees, Trees and diets, ICRISAT genebank, IITA genebank, GHUs, CGIAR policy, Diverse farming, De novo domestication
- Epic narratives of the Green Revolution in Brazil, China, and India. Symbols, heroes, heritage-making and we-will-do-it-even-better-next-time in the service of self-preservation and self-assertion. But, as we shall see below, not everything needs to be an epic success to be interesting, and useful.
- Using landscape genomics to infer genomic regions involved in environmental adaptation of soybean genebank accessions. Analysis of USDA collection shows that many haplotypes associated with high-latitude cold tolerance in China are still absent from modern American and European cultivars.
- Phenotypic evolution of the wild progenitor of cultivated barley (Hordeum vulgare L. subsp. spontaneum (K. Koch) Thell.) across bioclimatic regions in Jordan. Re-collecting after 23 years shows some loss of phenotypic diversity.

- A new method to reconstruct the direction of parent-offspring duo relationships using SNP array data and its demonstration on ancient and modern cultivars in the outcrossing species Malus × domestica. Sometimes it’s difficult to tell which variety is the parent and which the offspring.
- What are the links between tree-based farming and dietary quality for rural households? A review of emerging evidence in low- and middle-income countries. Meta-analysis shows that trees can help with diets, but it depends on a lot of things.
- Genebanks and market participation: evidence from groundnut farmers in Malawi. Improved peanut varieties derived from genebank accessions encourage market participation by farmers through expanding the area under cultivation, but not the amount sold.
- IITA’s genebank, cowpea diversity on farms, and farmers’ welfare in Nigeria. Improved varieties derived from genebank accessions don’t push out landrace diversity and are associated with higher yields and other benefits to farmers.
- The role of CGIAR Germplasm Health Units in averting endemic crop diseases: the example of rice blast in Bangladesh. The IRRI Germplasm Health Unit contributed about 2% to the benefits of the rice blast resistance breeding programme, but that’s a cost:benefit ratio of 112.
- Policy directions in public agricultural research: CGIAR’s public goods mandate and plant genetic resources. There has been too much focus on the “global” bit of “global public goods,” and opportunities have thus apparently been missed. The three papers above would like a word though.
