- Trees help natural enemies of pests in vanilla plantations.
- Cool video by Sherry Flint-Garcia on the history of maize. And its genetics.
- CIMMYT releases a bunch of interesting maize pre-breeding products, though they don’t call them that.

- Germplasm Acquisition and Distribution by CGIAR Genebanks. A lot of stuff going in, a lot of stuff coming out, to everyone’s benefit. 35 years of data, with special focus on the last 10.
- Intraspecific diversity as a reservoir for heat-stress tolerance in sweet potato. 132 out of 1973 accessions tolerant of heat, though in different ways. A prime example of the above benefits.
- Identification and characterization of high‐yielding, short‐duration rice genotypes for tropical Asia. Short-duration varieties will need to be a bit taller and leafier to yield more. Another example of the above benefits.
- Modelled distributions and conservation priorities of wild sorghums (Sorghum Moench). More stuff needs to go into the above genebanks, though, for example from N. Australia.
- Ex situ and in situ conservation gap analysis of crop wild relative diversity in the Fertile Crescent of the Middle East. Same from the Fertile Crescent.
- In situ and ex situ conservation gap analyses of crop wild relatives from Malawi. And not just the above genebanks either.
- The Potential of Payment for Ecosystem Services for Crop Wild Relative Conservation. Ok, we have the gaps (see above), and now here we have the method. What’s stopping us?
- Assessing under-Estimation of Genetic Diversity within Wild Potato (Solanum) Species Populations. Wild diploid species more diverse than previously thought. So providing more ecosystem services?
- Genetic diversity and differentiation of Olea europaea subsp. cuspidata (Wall. & G.Don) Cif. in the Hajar Mountains of Oman. No word on the ecosystem services being provided.
- The investigation of minor and rare Tunisian olive cultivars to enrich and diversify the olive genetic resources of the country. Rare + minor doesn’t mean bad. But maybe an influx of Omani genes would help?
- Biobanking of vegetable genetic resources by in vitro conservation and cryopreservation. Yes, even for vegetables.
- From landrace to modern hybrid broccoli: the genomic and morphological domestication syndrome within a diverse B. oleracea collection. Four subpopulations: Calabrese broccoli landraces, hybrids, sprouting broccoli, and violet cauliflower. Diversity in modern varieties decreasing with time.
- Crop switching reduces agricultural losses from climate change in the United States by half under RCP 8.5. But it will have to be a lot of switching. Hopefully out of broccoli.
- The mosaic genome of indigenous African cattle as a unique genetic resource for African pastoralism. An influx of zebu genes about a thousand years ago is responsible for the success of African pastoralism.
- Protection of traditional agricultural knowledge and rethinking agricultural research from farmers’ perspective: A case from Turkey. Against power imbalances the gods themselves contend in vain.

- Archaeological expansions in tropical South America during the late Holocene: Assessing the role of demic diffusion. Some agricultural diffusion in lowland South America was the movement of ideas rather than people.
- The origins of Amazonian landscapes: Plant cultivation, domestication and the spread of food production in tropical South America. Where did the farming people and/or ideas move from? The sub-Andean montane forest of NW South America and the shrub savannahs and seasonal forests of SW Amazonia.
- Genetic Diversity, Nitrogen Fixation, and Water Use Efficiency in a Panel of Honduran Common Bean (Phaseolus vulgaris L.) Landraces and Modern Genotypes. Landraces showed better N fixation, but lower yields, than modern varieties.
- Maize genotypes with deep root systems tolerate salt stress better than those with shallow root systems during early growth. Ok, but? There’s always a but.
- Challenges for Ex Situ Conservation of Wild Bananas: Seeds Collected in Papua New Guinea Have Variable Levels of Desiccation Tolerance. Avoid the basal end of the infructescence. Among other things.
- Detection of banana plants and their major diseases through aerial images and machine learning methods: A case study in DR Congo and Republic of Benin. Yeah but can you apply it to collecting the wild relatives?
- Genetic and genomic resources for finger millet improvement: opportunities for advancing climate-smart agriculture. No way this can be called neglected any longer. But is it still under-utilized?
- Genotyping-by-Sequencing to Unlock Genetic Diversity and Population Structure in White Yam (Dioscorea rotundata Poir.). More landrace variation within countries than among.
- BRIDGE – A Visual Analytics Web Tool for Barley Genebank Genomics. Do white yam next?
- Pedigree analysis of pre-breeding efforts in Trifolium spp. germplasm in New Zealand. Not a huge number of parents have been used, but reasonable diversity in most species.
- Pleistocene climate changes, and not agricultural spread, accounts for range expansion and admixture in the dominant grassland species Lolium perenne L. Lots more unused diversity out there. For now.
- IUCN Red List and the value of integrating genetics. Applying some genetic rules of thumb make some endangered species even more so.
- Variation in Seed Metabolites between Two Indica Rice Accessions Differing in Seed Longevity. Candidate biochemical indicators of impending seed death detected.
- Sustainability strategies by companies in the global coffee sector. They are close to non-existent.
- Camel Genetic Resources Conservation through Tourism: A Key Sociocultural Approach of Camelback Leisure Riding. Camel rides could be used for conservation, but they’ll have to deliver more than just conservation.
Nibbles: Insurance edition
- Biodiversity is insurance, says insurance company.
- Especially biodiversity of fruits and vegetables.
- Research by CGIAR into how best to use that insurance generates a 10:1 return on investment. Kind of. Covers breeding et al., but not genebanks. Sigh.
- Professor Claire Kremen is awarded the Volvo Environment Prize 2020 for research on how to protect that insurance while feeding the world.
- People have been fiddling with that insurance for longer than we thought, archeologists say.
Nibbles: Crop mapping, Sampling, Rice domestication, Coffee rust podcast, Wool dogs
- Crop-Climate Suitability Mapping. Yes, another one. I feel a proper post coming on.
- Tweet from Sean Hoban on ex situ sampling strategies. I feel a proper post coming on.
- Proper blog post explains a really complicated rice domestication paper in about a page.
- Proper podcast from Jeremy on, among other things, why coffee leaf rust is not why the Brits drink tea.
- Not sure if this is blog post, but it’s a really good example of weaving together (see what I did there?) different pieces of work on the wool dogs (sic) of the Pacific NW.
