- In Praise of Seed Morgues. You heard me. Webinar next week: sounds like a doozy.
- Plan of Action on Forgotten Foods. Another webinar next week.
- Walk into the Gateway. The GenRes Gateway, that is, “a crowd-sourced platform to guide you through the landscape of forest, plant and animal genetic resources in Europe.” A third webinar. Looks like I’ll be busy next week.
- Maybe I’ll read about how to evaluate agroecology in the meantime.
- Agroecology is not on FarmGeek, but other interventions are, like GMOs and “genetic diversity” (ie cultivar mixtures) and you can explore how effective they are around the world.
- Speaking of genetic diversity, there’s a lot of it in ICRISAT’s pearl millet fields at the moment, though not in cultivar mixtures. And breeders are having a busy week of it.
Managing seed on the web
The ambition of the CoEx ((Gouvernance adaptative des stratégies de gestion de la diversité cultivée)) project is to improve our understanding of the gap between (1) seed policies and laws and (2) farmers’ seed management practices. Such a gap is detrimental to the access and mobilization of a wide variety of seeds by farmers.
Intrigued? Speak French? There’s a webinar on the project today.
Brainfood: Lettuce, Little millet, Finger millet, Rice, Maize, Apple, Brassicas, Onions, Grapevine, Tomato, Sheep, Species diversity, Genetic diversity
- Whole-genome resequencing of 445 Lactuca accessions reveals the domestication history of cultivated lettuce. Originally domesticated in the Caucasus, for oil, and then a long, slow wander westward. But so much more to it…
- Variability and trait‐specific accessions for grain yield and nutritional traits in germplasm of little millet (Panicum sumatrense Roth. Ex. Roem. & Schult.). From 200 accessions to 5 both high yielding and rich in Ca.
- Genomic and phenotypic characterization of finger millet indicates a complex diversification history. Wait, East Africa is the least genetically diverse area?
- Portrait of a genus: the genetic diversity of Zea. There has been convergent adaptation in high altitude teosinte and high latitude (temperate) maize.
- Genetic diversity of African wild rice (Oryza longistaminata Chev. et Roehr) at the edge of its distribution. The Ethiopian material is special.
- Candidate genes and signatures of directional selection on fruit quality traits during apple domestication. Fruit colour and taste genes lose diversity during domestication.
- The Evolutionary History of Wild, Domesticated, and Feral Brassica oleracea (Brassicaceae). B. cretica is the closest wild relative.
- Brassica rapa domestication: untangling wild and feral forms and convergence of crop morphotypes. The truly wild stuff comes from the Caucasus, Siberia and … Italy. But it all goes back to turnips in the Hindu Kush.
- ‘Neodomesticates’ of the Himalayan allium spices (Allium species) in Uttarakhand, India and studies on eco-geography and morphology. Gotta know your onions.
- Multiple independent recombinations led to hermaphroditism in grapevine. The switch from dioecious to hermaphroditic flowers happened two times in the last 6000 years, but before domestication.
- Revitalization of the Greek Vitis database: a multimedia web-backed genetic database for germplasm management of Vitis resources in Greece. Welcome back!
- Participatory Plant Breeding and the Evolution of Landraces: A Case Study in the Organic Farms of the Collserola Natural Park. From 80 plants of the Mando tomato landrace to over 2000.
- Evidence for early dispersal of domestic sheep into Central Asia. Sheep were being kept in the Ferghana Valley 3000 years earlier than thought.
- A metric for spatially explicit contributions to science-based species targets. Sustainable crop production and forestry in Indonesia, Colombia, Mexico, Madagascar and Brazil would make a hell of a difference.
- Conserving intraspecific variation for nature’s contributions to people. Oh good, I’m glad somebody thought of this.
Yes we have banana catalogues
Great to hear that recent banana diversity collecting in my old stamping ground of the Pacific ((And, yes, we have blogged about this sort of thing before. And, yes, I do need to stop using this cliche in banana posts. But not today.)) has resulted in three beautiful germplasm catalogues:
- Rarotonga and Aitutaki, Cook Islands
- Upolu, Samoa
- West New Britain, Papua New Guinea
In due course, this material will end up in the Musa International Transit Centre and will be available for breeding, research and training under the SMTA of the Plant Treaty.
