- Genome-wide comparative diversity uncovers population structure, global distribution, and targets of selection in hexaploid oat. A worldwide survey reveals how oat diversity is structured, spread, and shaped by breeding, helping pinpoint untapped genetic resources for future improvement.
- Genomic diversity and the domestication history of cotton (Gossypium hirsutum). Its genome traces cotton’s journey from its wild origins in Mesoamerica while documenting the genetic narrowing that accompanied domestication.
- Genetic architecture of sugarcane traits in a polyploid genomics framework. New genomic tools finally begin to untangle the diversity of one of agriculture’s most genetically complex crops, exposing the basis of traits breeders have long selected largely in the dark.
- Projected warming will exceed the long-term thermal limits of rice cultivation. Rice has historically thrived within remarkably stable climatic boundaries. Those boundaries are now on course to be crossed across major growing regions, with profound implications for global food security. Diversity to the rescue?
- An inter-specific Amaranthus pangenome captures genetic variation potentially underlying key leafy vegetable traits in this underutilised crop. A rich reservoir of previously hidden diversity emerges from across multiple cultivated amaranths, offering breeders new options for improving a neglected but nutritious vegetable.
- Impact of gardening and nutrition support provided to women in refugee camps in Cox’s Bazar, Bangladesh. Even in one of the world’s most challenging humanitarian settings, greater interspecific crop diversity translated into better diets, improved food security, and enhanced wellbeing.
- Designing perennial crop-based agroforestry systems: specificities, challenges, and opportunities. Diversification does not stop at the field edge: how perennial crops can be combined with trees to deliver productive, resilient, and biodiversity-friendly farming systems.
- Towards Nature Positive supply chains: From biodiversity commitments to organisational action. What would it take to move biodiversity from corporate promises to business practice? Maybe the above examples can help turn aspiration into measurable action.
The wild bunch
Never rains but it pours. Along very similar lines as the previous post on a fun effort to document people’s favourite breadfruit varieties, here comes the FruitDev project’s Wild Fruit Population of the Month.
Each month, the series highlights one (or more) populations identified by a FRUITDIV partner, illustrating how field exploration, local knowledge, and cross-partner collaboration contribute to a better understanding of wild fruit genetic resources.
By focusing on individual populations, the series aims to make visible the often-overlooked genetic diversity found in natural and semi-natural landscapes, many of which are shaped by environmental pressures such as drought, poor soils, or past disturbances. These populations represent valuable reservoirs of adaptive traits that are increasingly relevant for resilience, conservation, and future breeding strategies.
This month’s featured population is a dwarf almond from North Macedonia. Nice idea.
A tale of many breadfruits
I can’t find anything online about the results of the regional Breadfruit Biocultural Conservation Knowledge Exchange Workshop organized by the Pacific Island Farmers Organisation Network (PFO) at the Tutu Rural Training Centre in Fiji from 27–29 April 2026. Beyond social media posts, that is. But I really like the idea of participants sharing the breadfruit varieties that are special to them.
Stairway to maize diversity
There’s a nice article in Rising Kashmir highlighting that region’s cold-tolerant maize landraces as a unique source of genetic diversity. What I liked about it is that it doesn’t condescend to its audience. It’s unapologetically technical and niche, while successfully (I think) striving to be understood by all. That’s rare. The author, Dr Salika Ramazan, argues that long adaptation to Himalayan environments has produced valuable traits for climate resilience and future maize breeding, and advocates for urgent conservation before this irreplaceable diversity is lost.
A quick search on Genesys revealed 302 maize accessions from above 1500 masl in the Himalayas (yellow on the map below), and 62 above 2500 masl (red). Of course, there are many more maize accessions from high altitudes in Central and South America, but their photoperiod adaptation (among other things) is likely to be quite different.
Brainfood: Markets edition
- “What is the essence of cultivating a crop that does not yield enough to feed my family?” Farmer agency and the management of agrobiodiversity in Ghana and Burkina Faso. Farmers balance subsistence needs and market opportunities when deciding which crop varieties to maintain. Well I never.
- Reassessing the economic returns of diverse traditional agricultural systems for smallholder farmers: a case study of the milpa in Mexico. Diverse traditional farming systems can generate significant economic value; so no, agricultural diversity is not necessarily less profitable than specialization for market production.
- Farmer participatory evaluation of Amaranthus cruentus L. breeding lines for marketable vegetable yield and organoleptic quality under on-farm and on-station conditions. In any case, farmers can work with researchers to select amaranth varieties with traits that improve both marketability and consumer appeal, linking crop improvement directly to market demand.
- Novel soybean type with improved volatile and sensory characteristics of raw soy slurries. Breeding soybean varieties with enhanced sensory qualities can hopefully increase consumer acceptance and create new market opportunities for soy-based foods. Unclear if farmers were involved, but they could have been..
- Can the digital long tail effect in farmers’ markets increase crop diversity on farms and in diets? Yes. Digital platforms can connect niche producers and consumers, creating markets for a wider range of crops, thereby encouraging agricultural and dietary diversity. How about linking seed producers to farmers?
- Preserving crop genetic diversity through traditional seed systems: insights from farmer-saved fonio (Digitaria exilis) landraces in Northern Ghana. Farmer-managed seed systems support the conservation of crop diversity while maintaining access to locally adapted varieties with potential market value. But maybe they could use a digital platform?
- Seeds and social norms: sorghum seed exchange among smallholder farmers in Northern Ethiopia. Cultural practices shape how farmers share seeds, influencing the circulation of crop diversity and farmers’ participation in local seed markets. Good luck with those digital platforms.
