- Genetic Diversity within a Global Panel of Durum Wheat (Triticum durum) Landraces and Modern Germplasm Reveals the History of Alleles Exchange. Modern varieties have a lot of rare alleles, and Ethiopian landraces may be the results of a separate domestication. But I’m not sure you can call this a core collection. Incidentally, genotyped by 35K Affymetrix Axiom wheat breeders array1 at TraitGenetics (Gatersleben, Germany).
- Genome Wide Association Study to Identify the Genetic Base of Smallholder Farmer Preferences of Durum Wheat Traits. Farmers know what they’re talking about. No word on any overlap with above. Incidentally, genotyped on the Infinium 90K wheat chip at TraitGenetics (Gatersleben, Germany). There’s a coincidence!
- The role of livestock intensification and landscape structure in maintaining tropical biodiversity. If we want to keep more livestock while maintaining biodiversity, we should spare forests and avoid using agrochemical inputs. Assuming that dung beetles can stand in for tropical biodiversity as a whole.

A sustainable way forward for public plant breeding
How can public plant breeding programs reap royalties and research investments while keeping their cultivars in the public domain?
Good question. For some answers, see the proceedings on the 2016 Intellectual Property Rights for Public Plant Breeding Summit, released yesterday by the University of Wisconsin-Madison’s College of Agricultural and Life Sciences.
Here’s the organizer, Bill Tracy:
For many years now, we have heard how public plant breeding has been on the decline. What was exciting about this meeting is that we heard real world solutions implemented by colleges and technology transfer agencies that not only support current cultivar development but have increased the number of plant breeders, crop varieties released, and royalties generated.
In an era of continuing consolidation on the private side, it’s good to see public sector plant breeding making a stand.
Brainfood: Kolli Hills diversity, Fergana diversity, Chinese rice terraces, ICRISAT prebreeding, Spanish CWR collecting, Edible flowers, Diversification, Prices vs volatility
- An ethnographic exploration of perceptions of changes in dietary variety in the Kolli Hills, India. Cassava cash cropping has had unforeseen effects on dietary diversity.
- Mapping and assessing crop diversity in the irrigated Fergana Valley, Uzbekistan. More crops on the edges.
- An Analysis on Crops Choice and Its Driving Factors in Agricultural Heritage Systems—A Case of Honghe Hani Rice Terraces System. Established for “red rice”, but that’s not enough.
- Prebreeding Using Wild Species for Genetic Enhancement of Grain Legumes at ICRISAT. It’s not easy, but it’s been worth it.
- A Multispecies Collecting Strategy for Crop Wild Relatives Based on Complementary Areas with a High Density of Ecogeographical Gaps. Collecting in Spain in “…top 10 selected complementary areas would allow the capture of 59 of the 88 targeted taxa and 31% of the 683 different taxa-ELC category combinations identified in the ecogeographical gaps.”
- Antioxidant power, anthocyanin content and organoleptic performance of edible flowers. Tycoon Blue will be quite the marketing challenge.
- Diversifying Food Systems in the Pursuit of Sustainable Food Production and Healthy Diets. And nary an edible flower mentioned.
- Cereal price shocks and volatility in sub-Saharan Africa: what really matters for farmers’ welfare? Prices.
Brainfood: African tea, Iranian olives, Persistent identifiers, Fast breeding, Lablab domestication, Pea origin, Celebs & conservation, Ancient dope, Sugarcane evolution, Chicken selection
- Multiple origins and a narrow genepool characterise the African tea germplasm: concordant patterns revealed by nuclear and plastid DNA markers. It’s a “potpourri,” but kinda missing Chinese Assam stuff.
- The eastern part of the Fertile Crescent concealed an unexpected route of olive (Olea europaea L.) differentiation. It was in Iran before domestication.
- Identifiers for the 21st century: How to design, provision, and reuse persistent identifiers to maximize utility and impact of life science data. Why DOIs succeeded, and why something like them needs to be applied to biological specimens, including genebank accessions, to combat “desultory citation practices”. But we knew that.
- Speed breeding: a powerful tool to accelerate crop research and breeding. Can double the number of generations per unit time with fully-enclosed controlled-environment growth chambers.
- Evidence for two domestication events of hyacinth bean (Lablab purpureus (L.) Sweet): a comparative analysis of population genetic data. With the 2-seeded group domesticated in Ethiopia, the 4-seeded somewhere else in Africa.
- Refinement of the collection of wild peas (Pisum L.) and search for the area of pea domestication with a deletion in the plastidic psbA-trnH spacer. Maybe not Turkey.

- Cannabis in Eurasia: origin of human use and Bronze Age trans-continental connections. Proto-Indo-Europeans were real stoners.
- Analysis of Three Sugarcane Homo/Homeologous Regions Suggests Independent Polyploidization Events of Saccharum officinarum and Saccharum spontaneum. It’s really complicated, not least because of plant breeders.
- Genomic Comparison of Indigenous African and Northern European Chickens Reveals Putative Mechanisms of Stress Tolerance Related to Environmental Selection Pressure. African chickens able to withstand high temperatures due to a region on chromosome 27 and European chickens low temperatures due to region on chromosome 2.
