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.”

If you’re interested in Champa rice, there’s a whole paper about it.
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.

Nibbles: Zimbabwe breeder, Indian genebank, Zambian genebank, Chinese genebank, Pakistan & Uzbekistan, Manchester planting
- Sorghum and millet breeder honoured in Zimbabwe. Always good to see.
- Germplasm evaluation efforts of Indian national genebank make it into the mainstream financial press. Also very good to see.
- Zambian national genebank does some much-needed safety duplication. More good news.
- Possibly good news, hard to say: Russian news agency on what seems to be a new wild rice genebank in China.
- Always good news to see two countries agree to collaborate on genetic resources.
- Manchester viaduct gets a greenlift. Good to see it, despite no genebanks being involved.
