A new genebank for the ages is set for ages
Great news from the opening ceremony of the new Future Seeds genebank in Palmira, Colombia on 15 March:
The Bezos Earth Fund pledged US$17 million for Future Seeds, a new CGIAR genebank inaugurated today. The new genebank will bolster global efforts to safeguard the world’s future food supply.
This genebank is truly next-level:
Future Seeds is the most advanced facility in Latin America and is expected to become the first ever platinum-level LEED (Leadership in Energy and Environmental Design)-certified genebank building in the world. Its Data Discovery and Biotechnology Lab will use big-data technologies to mine the genebank using the latest in genetics to document the range of possibly useful traits in the current collection. Other breakthrough technologies across genebanks include drones and robotic rovers, which are helping analyze crop characteristics in the field more rapidly, and the use of artificial intelligence to enable collectors to identify potential biodiversity hotspots in nature.
Here, check it out for yourselves:
And here’s an overview of the collections from Genesys (beans in red, cassava blue, forages green).

A champion rice going for a song in China
A few days back Jeremy shared with me a blog post he had come across that made reference to a documentary that in turn featured an old scroll from China’s Song Dynasty:
The documentary had a nice section about a scroll produced in this period, showing the scrum of life along a river during a festival. It is apparently one of the most famous images in all of Chinese history, so, I feel chastened never to have heard of it previously.
The scroll is online, with annotations along the way to help you understand what’s going on. They’re all pretty interesting, but the very last one is particularly relevant to us here. It’s associated with a farmhouse in some paddy fields.
Here’s what is says.
New Varieties of Rice
A farm house on the outskirts of the city. “In the early part of the Song dynasty … a new variety of early-ripening rice was introduced into China from Champa, a kingdom then located near the Mekong River Delta in what is now Vietnam, and by 1012 it had been introduced in the lower Yangzi and Huai river regions. … Because the variety of rice was relatively more drought-resistant, it could be grown in places where older varieties had failed, especially on higher land and on terraces that climb hilly slopes, and it ripened even faster than the other early-ripening varieties already grown in China. This made double-cropping possible in some areas, and in some places, even triple-cropping became possible … the hardiness and productivity of various varieties of rice were and are in large part responsible for the density of population in South, Southeast, and East Asia. According to the Buddhist monk, Shu Wenying, the Song Emperor Zhengzhong (998-1022), when he learned that Champa rice was drought-resistant, sent special envoys to bring samples back to China.”
Lynda Noreen Shaffer, in “A Concrete Panoply of Intercultural Exchange: Asia in World History,” in Asia in Western and World History, edited by Ainslie T. Embree and Carol Gluck (Armonk, N.Y.: M.E. Sharpe, 1997), 839-840.
If you’re interested in Champa rice, there’s a whole paper about it.
Turkey Red from Ukraine feeds America, and the world
As we ponder the possible effects of war on food security, a piece in Modern Farmer reminds us that Ukraine contributes to the world’s wheat crop more than just its annual harvest.
“If you’ve ever eaten a slice of bread, you can thank Ukraine. That’s not an exaggeration. The flavorful grains that transformed the North American prairies during the nineteenth century into a continental breadbasket were varieties native to Ukraine’s famed Black Earth districts of Crimea and Galicia [what is now southeastern Poland and western Ukraine].”
It has to do with the “Turkish type” hard red winter wheats that German Mennonite farmers, originally invited into the Russian empire by Catherine the Great, took with them to the US from the Crimea when things got tricky for them in the late 1800s.
Dr Tom Payne, formerly the head of the wheat genebank at CIMMYT, tells me that such varieties as Kharkov, Kherson and Kubanka were the foundation for Great Plains modern wheats, with Kharkov being the “check” against which new varieties have been compared for more than 50 years.
A few years ago, Jeremy told the story of Red Fife on his podcast. A foundational variety for Canadian wheat farming, that too can perhaps trace its ultimate origin to Ukraine.
One legend states that a load of wheat grown in Ukraine was on a ship in the Glasgow harbour. A friend of Farmer Fife dropped his hat into the red-coloured wheat, collecting a few seeds in the hatband, which he then shipped off to Farmer Fife. The wheat grew. The family cow managed to eat all the wheat heads except for one, which Mrs Fife salvaged. This was the beginning of Red Fife wheat in Canada.
Lately, some American and Canadian farmers, millers and bakers have been going back to older heritage varieties such as Turkey Red and Red Fife; and now, alas, these are making their way back home, though sadly not as one would have wished:
Janie’s Mill, which grinds grains from Janie’s Farm in central Illinois, sent customers a note about being the “direct beneficiaries of countless generations of Ukrainian wheat farmers.” In service of that direct connection, the mill is sending profits from sales of Turkey Red grains and flour to World Central Kitchen, which has been providing hot meals in the region to feed the more than two million refugees that have fled Ukraine since the attack began in February.
Brainfood: Kungas, Tomato domestication, Wild honeybees, Association mapping, Mixtures, Wild edible plants, DSI ABS, Fusarium wilt, Mango weeds, Conservation payments
- The genetic identity of the earliest human-made hybrid animals, the kungas of Syro-Mesopotamia. According to 4500 year old DNA, these super-donkeys were sterile crosses between female domestic donkeys and wild male asses. I guarantee nothing below will be as much fun as this.
- Haplotype analyses reveal novel insights into tomato history and domestication driven by long-distance migrations and latitudinal adaptations. I was wrong. Turns out tomatoes came about by one wild species evolving into a semi-domesticated one during a gradual migration from the Peruvian deserts to the Mexican rainforests and that fully domesticated Peruvian and Ecuadorian populations were the result of more recent back-migrations.
- Semi-natural habitats promote winter survival of wild-living honeybees in an agricultural landscape. Wrong again. Rare wild honeybees have been found in Galician power poles.
- High-resolution association mapping with libraries of immortalized lines from ancestral landraces. Actually, immortal landraces sound pretty cool too.
- From cultivar mixtures to allelic mixtures: opposite effects of allelic richness between genotypes and genotype richness in wheat. Mixtures of inbred lines are generally better than pure stands for coping with blotch disease, but sometimes specific allelic combinations undermine this. Well, ancient super-donkeys it ain’t, but still.
- Local communities’ perceptions of wild edible plant and mushroom change: A systematic review. The literature shows that local people are worried about the decreased abundance of the wild plants they rely on for food and nutrition security.
- Weeds Enhance Pollinator Diversity and Fruit Yield in Mango. That should be “weeds.” They’re not weeds if they’re actually useful. Maybe some of them are even edible.
- Multilateral benefit-sharing from digital sequence information will support both science and biodiversity conservation. We need a multilateral DSI benefit-sharing system which decouples access to DSI from sharing the benefits of DSI use. Where have I heard that before? And can I hear more about ancient hybrid super-donkeys instead?
- Diversity of Fusarium associated banana wilt in northern Viet Nam. The dreaded TR4 is still rare, but the pathogen lurks among the wild species too.
- Payments for Conservation of Animal Genetic Resources in Agriculture: One Size Fits All? I wonder what size would fit a hybrid super-donkey.
