- International Lima Bean Network: from the origin of the species to modern plant breeding. And you can join it here.
- Solving the mystery of Obake rice in Africa: population structure analyses of Oryza longistaminata reveal three genetic groups and evidence of both recent and ancient introgression with O. sativa. The wild African O. longistaminata is closer to Asian O. sativa than to other African wild species, and shows evidence of ancient introgression from O. sativa in southern Africa. Definitely worth a network.
- The origins and evolutionary history of feral apples in southern Canada. They are mainly recombinants involving early heritage cultivars, with no hybridization with local wild species. So, not like rice in Africa.
- Can seed exchange networks explain the morphological and genetic diversity in perennial crop species? The case of the tropical fruit tree Dacryodes edulis in rural and urban Cameroon. Cities are hotspots of African plum diversity because people bring in tress from all over the place. So, a bit like apples in Canada.
- Ancient Potato Varieties of the Canary Islands: Their History, Diversity and Origin of the Potato in Europe. “The Andes end in the Canary Islands.” A bit like how the Caucasus ends in Canada?
- Functional diversification of a wild potato immune receptor at its center of origin. Wild species can be used to improve the late blight tolerance of cultivated potatoes.
- Limited-transpiration trait in response to high vapor pressure deficit from wild to cultivated species: study of the Lens genus. Wild species can be used to improve the drought tolerance of cultivated lentils.
- A Tunisian wild grape leads to metabolic fingerprints of salt tolerance. Wild species can be used to improve the salt tolerance of cultivated grapes.
- Characterization of the genetic composition and establishment of a core collection for the INERA Robusta coffee (Coffea canephora) field genebank from the Democratic Republic of Congo. From 730 shrubs to 263 unique genotypes to 10 plants with 93% of the alleles. Some wild stuff involved. Do the same for African plum?
- Genetic diversity within landraces of barley (Hordeum vulgare L.) and its implications on germplasm collection and utilization. Maybe we should do core collections for each landrace?
- Phenotyping and identification of target traits for de novo domestication of wheat wild relatives. Maybe we should try it with that wild African rice too.
Happy retirement to USDA’s Dr Peter Bretting
Congratulations to Dr Peter Bretting on his imminent retirement from USDA.
After 32+ years of dedicated public service, Dr. Peter Bretting is retiring from his post as Senior National Program Leader for Plant Germplasm and Genomes with the USDA-ARS Office of National Programs. Dr. Bretting has been with National Programs since 1998. Previous to this post, he served as Research Leader and Coordinator, USDA-ARS, North Central Regional Plant Introduction Station (NCRPIS), and USDA-ARS Collaborator-Associate Professor of Agronomy and Botany, Iowa State University. Prior to joining USDA-ARS, he served as Research Program Director, Indiana Crop Improvement Association, and Adjunct Assistant Professor of Botany and Plant Pathology, Purdue University.
He rides off into the sunset on a high, having masterminded the USDA’s new National Strategic Germplasm and Cultivar Collection Assessment and Utilization Plan, as requested by the 2018 Farm Bill. That directed the USDA to “develop and implement a national strategic germplasm and cultivar collection assessment and utilization plan that takes into consideration the resources and research necessary to address the significant backlog of characterization and maintenance of existing accessions considered to be critical to preserve the viability of, and public access to, germplasm and cultivars.”
Quite the parting gift. And a worthy final touch to an enormous legacy.
There’s a celebration of Dr Bretting’s career and tremendous contributions to plant genetic research and crop genetics, genomics and systematics on Monday, 18 December 2023 at 1:00-3:00 pm EST. Let me know if you’d like the ZOOM link.
Very best wishes for a long and happy retirement, Peter!
Nibbles: Seed system, Food system, Coffee infographic, African agroecology, ENRICH, Land Institute citizen science
- Do you want to describe and analyze seed systems? Let the Norwegian University of Life Sciences show you how.
- Do you think there should be a, well, systemic approach to the food system? So does the Swedish University of Agricultural Sciences. Hope they include seed systems. And genebanks.
- Want a rather beautiful way to remember the complicated history of coffee? Let Chris Kornman sell you one. A time when botanic gardens acted as genebanks.
- Looking for an African take on African agricultural development? Million Belay has you covered. Wish he had mentioned African genebanks though.
- Would you like to celebrate 20 years of HarvestPlus? IFPRI to the rescue.
- Want to grow perennial crops for the Land Institute? Well now you can.
Nibbles: PlantSearch, Ranking apples, Pumpkin pix, Fruit pix, Livestock maps, Impact
- Searching for plants in botanic gardens.
- Searching for the best apple.
- Searching for pumpkins and squashes.
- Searching the Pomological Watercolor Collection.
- Searching for livestock.
- Searching for varietal turnover. And other kinds of impact.

- A New Methodological Approach to Detect Microcenters and Regions of Maize Genetic Diversity in Different Areas of Lowland South America. Multiple disciplines identify 4 microcenters of maize diversity in the lowlands of South America.
- Historical Routes for Diversification of Domesticated Chickpea Inferred from Landrace Genomics. Genomics identifies both Indian and Middle Eastern traces in Ethiopian chickpeas.
- Crop wild relatives in Lebanon: mapping the distribution of Poaceae and Fabaceae priority taxa for conservation planning. Spatial analysis identifies a couple of key ex situ and in situ conservation areas for CWR in Lebanon.
- Analysis of gaps in rapeseed (Brassica napus L.) collections in European genebanks. Spatial analysis identifies a few key ex situ and in situ conservation areas for rapeseed wild relatives in Europe.
- Genomic and population characterization of a diversity panel of dwarf and tall coconut accessions from the International Coconut Genebank for Latin America and Caribbean. Characterization of various sorts identifies different Atlantic and Pacific coconut genepools in the Western Hemisphere.
- Pleistocene-dated genomic divergence of avocado trees supports cryptic diversity in the Colombian germplasm. Genomics identifies a uniquely Colombian avocado genepool.
- Analysis of >3400 worldwide eggplant accessions reveals two independent domestication events and multiple migration-diversification routes. Genomics identifies separate Southeast Asia and Indian areas of domestication, and limited exchange between them.
- Population genomics identifies genetic signatures of carrot domestication and improvement and uncovers the origin of high-carotenoid orange carrots. Genomics identifies wester-central Asia as the area of carrot domestication in the Early Middle Ages, and western Europe as the place where the orange variant was selected in the Renaissance.
- A Citrullus genus super-pangenome reveals extensive variations in wild and cultivated watermelons and sheds light on watermelon evolution and domestication. Pangenomics identifies a gene in wild Kordofan melons as promoting the accumulation of sugar in watermelon.
- Pangenome analysis provides insight into the evolution of the orange subfamily and a key gene for citric acid accumulation in citrus fruits. Pangenomics identifies south central China as the primary centre of origin of the genus Citrus.
- Pangenome analyses reveal impact of transposable elements and ploidy on the evolution of potato species. Pangenomics identifies wild species from North and Central America as having lots of genes for abiotic stress response, but also fewer transposable elements.
- Pangenomic analysis identifies structural variation associated with heat tolerance in pearl millet. Pangenomics identifies the key genes and structural variations associated with pearl millet accessions from the most hot and dry places.
- Dark side of the honeymoon: reconstructing the Asian x European rose breeding history through the lens of genomics. Genomics and other data identifies a shift from a European to a mainly Asian genetic background in cultivated roses during the 19th century, leading to a narrowing of genetic diversity.
