Unfried beans

Are you interested in populations that happen to be hybrids between common beans and some other species? Well, so are our friends at CIAT, and they’re involved in a project with NIAB in the UK to study these hybrid populations from their genebank:

The idea is to see if they could be used in breeding for climate change adaptation.

Researchers will be exploring common bean hybrid populations to learn more about their physical characteristics, genetics, responses to disease and ease of use for breeding programmes.

You can catch up on the latest findings on the NIAB website, but also in an online workshop on March 1.

Brainfood: Spatial data, Extinction risk, Improved lentils, Lentil collection, Ohia germination, Shea genomics, Wild olive, Cacao climate refugia, Cacao sacred groves, Italian winter squash, Nigerian yams, Bambara groundnut diversity

CropHarvest: A global dataset for crop-type classification. 90,000 datapoints all over the world, nicely labelled with what’s going on there agriculturally speaking. Let the AI rip.
Using publicly available data to conduct rapid assessments of extinction risk. Pretty much useless, but at least now we know why. Should have used AI.
Plot-level impacts of improved lentil varieties in Bangladesh. About 15% higher yields and gross margins, resulting in lots of savings on imports.
Agro-Morphological Characterization of Lentil Germplasm of Indian National Genebank and Development of a Core Set for Efficient Utilization in Lentil Improvement Programs. And a core subset to boot. Unclear if any were used to breed the above.
Variation in Germination Traits Inform Conservation Planning of Hawaiʻi’s Foundational ʻŌhiʻa Trees. Germination was lower from some populations than from others, but not because of environmental factors.
Genomic Resources to Guide Improvement of the Shea Tree. Ok, great, but now what exactly? And no word on germination…
Current Status of Biodiversity Assessment and Conservation of Wild Olive (Olea europaea L. subsp. europaea var. sylvestris). When can we expect something similar for shea tree?
Extreme climate refugia: a case study of wild relatives of cacao (Theobroma cacao) in Colombia. The forest areas where wild cacao has survived the longest, and is particularly diverse, will be cut in half in 50 years. I wonder what the figures are for wild olive.
Soil biomarkers of cacao tree cultivation in the sacred cacao groves of the northern Maya lowlands. Maybe re-introduce it? More here.
How to save a landrace from extinction: the example of a winter squash landrace (Cucurbita maxima Duchesne) in Northern Italy (Lungavilla-Pavia). It’s great to have ‘Berrettina di Lungavilla’ back, but 7 years for one landrace? No sacred groves involved. Shea harvesters unavailable for comment.
Collection, characterizaton, product quality evaluation, and conservation of genetic resources of yam (Dioscorea spp.) cultivars from Ekiti State, Nigeria. At least it’s more than one landrace.
Genetic Diversity and Environmental Influence on Growth and Yield Parameters of Bambara Groundnut. 95 landraces, no less. All safe from extinction. Right?

Nibbles: Wild coffee, Humble potato, Banana seeds video, Citizen Bean, Svalbard, Microlivestock, Transhumance, Exotic tea, BIPOC heirlooms

The Food Programme does coffee wild relatives.
Potatoes are not that bad nutritionally.
Getting banana seeds.
Want to do citizen science with beans?
The latest from Svalbard.
Bugs again?
Counting sheep.
Weird tea is the best tea. But any tea will do in a pinch.
BIPOC communities saving heirloom seeds.

Brainfood: Aspen mapping, Biodiversity & ag, Mining forages, China forages, China groundnuts, Soil microbes, Agroecology messaging, Old wood, Ugandan sorghum, New wild sweetpotato, Tasty fruits

Remote sensing of cytotype and its consequences for canopy damage in quaking aspen. You can tell diploid from triploid trees from space.
Future global conflict risk hotspots between biodiversity conservation and food security: 10 countries and 7 Biodiversity Hotspots. Fancy maths tells us biodiversity and agriculture are most in conflict in DRC, Sierra Leone, Malawi, Togo, Zambia, Angola, Guinea, Nigeria, Laos, and Cambodia.
Allele mining in diverse accessions of tropical grasses to improve forage quality and reduce environmental impact. A draft reference genome from a single species tells us about 7 potentially useful alleles among 104 clearly very well chosen accessions of Urochloa spp and Megathyrsus maximus.
Research Status of Forage Seed Industry in China. I wonder how many of the above alleles can be found in the Chinese forage collection. Might be easier to eventually find out if the website supposedly serving up the national forage germplasm resource management system actually worked.
Safe conservation and utilization of peanut germplasm resources in the Oil Crops Middle-term Genebank of China. We are even told about some individual interesting accessions, though not how to get hold of them.
The impact of crop diversification, tillage and fertilization type on soil total microbial, fungal and bacterial abundance: A worldwide meta-analysis of agricultural sites. Meta-analysis tells us that use of organic fertilisers and reduced tillage are associated with more microbes, fungi and bacteria in the soil.
Detecting the linkage between arable land use and poverty using machine learning methods at global perspective. Machines tells us that higher crop yields and more fertilisers are associated with lower poverty levels. Non-machines are shocked. No word on soil microbial abundance.
The 10 Elements of Agroecology: enabling transitions towards sustainable agriculture and food systems through visual narratives. Well, these 10 are not only the elements of agroecology, so they could tell us about other messaging too.
Regional Patterns of Late Medieval and Early Modern European Building Activity Revealed by Felling Dates. Tree rings in old buildings tells us more felling where and when grain prices were low and mining activity high. No machines involed.
Genetic diversity analysis and characterization of Ugandan sorghum. A tropical genebank collection can tell us about temperate-adapted germplasm, if we know how to ask.
Discovery and characterization of sweetpotato’s closest tetraploid relative. Meet Ipomoea aequatoriensis T. Wells & P. Muñoz sp. nov. from, well, Ecuador.
Metabolomic selection for enhanced fruit flavor. Another machine tells us how to pick tasty tomatoes and blueberries from chemical profiles. No word on when it will be able to describe new species.

Scaling up neodomestication for climate-ready crops. Ok, but when is enough enough?
Can Feeding a Millet-Based Diet Improve the Growth of Children? — A Systematic Review and Meta-Analysis. Yes. So maybe make the most of the crops we already have?
Does vitamin A rich orange-fleshed sweetpotato adoption improve household level diet diversity? Evidence from Ghana and Nigeria. Sometimes. So maybe make the most of the crops we already have?
Global interdependence for fruit genetic resources: status and challenges in India. So many crops out there.
DATASET: The World Vegetable Center okra (Abelmoschus esculentus) core collection as a source for flooding stress tolerance traits for breeding. This is one way of making the most of the crops we already have.
The floating garden agricultural system of the Inle lake (Myanmar) as an example of equilibrium between food production and biodiversity maintenance. This is another way of making the most of the crops we already have.
Phenotyping a diversity panel of quinoa using UAV-retrieved leaf area index, SPAD-based chlorophyll and a random forest approach. Oh look, here’s another, and all you need is a drone and fancy maths.

Prehistoric Farming Settlements in Western Anatolia. What, only 5 crops?
Two divergent haplotypes from a highly heterozygous lychee genome suggest independent domestication events for early and late-maturing cultivars. Ancient farmers knew what they were doing after all, eh?
Expected global suitability of coffee, cashew and avocado due to climate change. Millennials could be in trouble if new crops don’t come along.
Traditional Foods From Maize (Zea mays L.) in Europe. Maybe European millennials could eat more maize.
Growing maize landraces in industrialized countries: from the search for seeds to the emergence of new practices and values. Nah, let’s domesticate something else instead.

1. Collecting tree seeds properly and respectfully is not easy.
2. No word on how easy it is to collect tepary beans respectfully.
3. Helping the USDA with their germplasm evaluations, on the other hand, is a breeze. Any tepary beans?
4. Seed Savers Exchange makes conserving seeds look easy. Spoiler alert: it isn’t.
5. It seems to be very easy to open new national genebanks in China.
