- Iron beans in Rwanda: crop development and delivery experience. 800,000 households, discontinuation rate 11%. But the health outcomes? Too early, I guess.
- Phylogenetic origin of limes and lemons revealed by cytoplasmic and nuclear markers. It’s so VERY complicated.
- Seed producer cooperatives in the Ethiopian seed sector and their role in seed supply improvement: A review. Sitting between the formal and informal seed systems, they “play a key role in meeting seed demand and contribute greatly to seed supply improvement through high-volume production of seed, crop, and variety diversification, and seed delivery to farmers.”
- Gamification of farmer-participatory priority setting in plant breeding: Design and validation of “AgroDuos”. Based on pairwise ranking. I remember doing it by hand, but it’s nice to have the app. And there’s more.
- Emerging Avenues for Utilization of Exotic Germplasm. It comes down to the collections being better characterized and understood.
- Genetic resource policies in international collaborative research for food and agriculture: A study of USAID-funded innovation labs. Transaction costs are rising. Well, yeah.
- Plums: A Brief Introduction. Will keep you regular.
- Characterization and phylogenetic analysis of ancient Italian landraces of pear. Some synonyms found, some unknown things identified. All very worthy.
- Genetic diversity and a population structure analysis of accessions in the Chinese cowpea [Vigna unguiculata (L.) Walp.] germplasm collection. The Chinese stuff is different to the African stuff.
- Out of Borneo: biogeography, phylogeny and divergence date estimates of Artocarpus (Moraceae). Yeah but how many can you eat?
- Effective seed harvesting strategies for the ex situ genetic diversity conservation of rare tropical tree populations. “…fewer seeds from each of a larger number of trees, … from peripheral subdivided regions of the population.”

- Participate!
- In plant breeding, that is.
- And seed systems too, natch.
- And you too could come up with the world’s hottest pepper.
- Or help save a heritage breed.
- Or sustainably harvest Himalayan nettle.
- But careful not to get high on this chocolate hack.
- Though binging on avocado is perfectly acceptable.
- And for goodness’ sake, watch out for those Russians.
Brainfood: CWR use, Mainstreaming, Duplicates, Phaseolus model, Cherimoya diversity, Legume mixtures, ICRISAT pearl millet, Taste breeding, Rhubarb rhubarb, Plasticity, Seed dispersal
- The Use of Crop Wild Relatives in Maize and Sunflower Breeding. In maize, unlike sunflower, it just hasn’t been worth it. Yet.
- Securing sustainable and nutritious food systems through mainstreaming agricultural biodiversity: an interdisciplinary study. What works in Brazil won’t necessarily fly in India.
- Duplication assessments in Brassica vegetable accessions. Half of 13 accession pairs/triplets with identical names from VIR and NordGen turned out to be morphologically identical.
- Beans (Phaseolus ssp.) as a Model for Understanding Crop Evolution. 7 independent domestication “events” spread across 5 species and 2 continents makes for some interesting natural experiments.
- A Mesoamerican origin of cherimoya (Annona cherimola Mill.). Implications for the conservation of plant genetic resources. Compare and contrast with above.
- Highly productive forage legume stands show no positive biodiversity effect on yield and N2-fixation. Sometimes diversity doesn’t add much.
- Genetic Resources of Pearl Millet: Status and Utilization. 22,888 accessions from 51 countries. Indian landraces: earliness, high tillering, high harvest index and local adaptation; African: bigger panicles, large seed size, and disease resistance.
- Use of natural diversity and biotechnology to increase the quality and nutritional content of tomato and grape. Both are needed.
- Rhubarb (Rheum species): the role of Edinburgh in its cultivation and development. From China, via Russia, with love.
- Will phenotypic plasticity affecting flowering phenology keep pace with climate change? If the change is smaller than about 13 days.
- Seed dispersers help plants to escape global warming. Because they move seed >35 m per decade uphill.
New CGIAR portfolio off and running
CGIAR launched its new portfolio yesterday, there was a Twitter chat thing, and I wrote a blog post about the Genebanks Platform. Not many people hurt.
How genetic improvement and crop intensification improve wellbeing
Mapping crops: Are we there yet?
I ran across a bunch of nice crop maps on the internet 1, so I made a GIF for you (click on it to get it cycling).
You’re welcome.
I’m reliably informed the source is Monfreda et al. (2008). You can download the data in multiple formats, but I don’t think I’ve ever seen the headline maps displayed all together as The Decolonial Atlas has done, albeit without attribution, which is naughty.
Anyway, people have obviously taken the trouble to download and play around with the data. For example, they have been ably mashed up by Bioversity to get a global crop diversity map.
Which, in turn, it is instructive to compare with the one from the Lancet Planetary Health map we blogged about a few days ago.
But which dataset to use to do this kind of stuff? Monfreda’s is only one of many.
I see that we now, after a long wait, have WordClim 2, thanks to the work of our friend Robert Hijmans and his colleagues. 2 Is it too much to hope for that he’ll now turn his hand to producing the definitive crop distribution dataset? 3 Maybe something for the CGIAR’s Big Data Platform, just launched, to think about organizing, convening, and/or inspiring.
