- Implication of high variance in germplasm characteristics. Last week’s Brainfood focused on genomic variation. This week, in contrast, we look at phenotyping. But not old school phenotyping, oh no. This paper, for example, uses fancy-ish, but not especially expensive, imaging.

- Mezcal worm in a bottle: DNA evidence suggests a single moth species. I rest my case.
Brainfood: Food biodiversity, Diversification, New crops, GMO maize, African livestock, Greek innovation clusters, Amazonian native cacao
- Food Biodiversity as an Opportunity to Address the Challenge of Improving Human Diets and Food Security. Biodiversity and food security can be mutually supportive, but you need education, research and inclusion, say educators and researchers.
- Achieving win-win outcomes for biodiversity and yield through diversified farming. Biodiversity and yield both win in only about a quarter of cases. But humanity does not live by yield alone, right?

Nibbles: Spanish wine, Wild bananas, African tree seeds, Ancient Foodways, Coffee genotyping, Barbados genebank, Modern plant breeding myths, Yam seeds, Climate funding for food systems
- There’s a piece in The Guardian on how Spanish wine makers are fighting climate change by going back to old grape varieties like estaladiña.
- Maybe the same will happen with bananas, and its wild relatives could help? If so, it’s good we have this nifty catalogue.

- Meanwhile, Barbados is still thinking about building a genebank.

- Yam researchers in Benin have their own take on improving agricultural practices.
- More climate funding should go to food system transformation, says the Global Alliance for the Future of Food in a report. Those Spanish winemakers — and everyone else above — would probably agree.
Brainfood: Why measure genetic diversity?
- Genetic diversity goals and targets have improved, but remain insufficient for clear implementation of the post-2020 global biodiversity framework. The struggle to ensure recognition of the importance of measuring genetic diversity is real, despite the available tools. And despite the range of uses to which the results can be put, as illustrated in the following papers.
- DNA barcoding markers provide insight into species discrimination, genetic diversity and phylogenetic relationships of yam (Dioscorea spp.). Measuring genetic diversity can help you tell species apart.
