- All of the presentations from the World Congress on Agroforestry.
- Scuba rice in 13 slides.
- You got off easy on that last one. Here’s 55 slides on fish biodiversity and the food supply.
- Not much fish in the food supply of early farmers in Britain.
- New IFPRI book highlights technologies to beat hunger. Includes plant breeding. But no fish?
- Kenyan agroforestry organization gets C credits. Details sketchy though.
- The Bible got it wrong on camels. And that’s all I’m saying about that.
- Cuneiform tablets are so beautiful. Especially when they depict agricultural biodiversity. Via.
French grape genebank on the move?
After Pavlovsk and Brogdale, it is now the turn of a French fruit genebank to feel the heat. According to Declan Butler’s somewhat breathless piece in Nature:
Uncertainty hangs over one of the world’s largest and most important grapevine collections. The Domaine de Vassal vineyard, on France’s Mediterranean coast, houses a vast sweep of grape biodiversity that is essential to research and winegrowers in France and around the world.
That would be the Station de Recherches Viticoles of the Institut national de la recherche agronomique (INRA). For those that know genebank-speak, that is institute FRA139. Plug that into the “institute code” slot on ECPGR’s Vitis database page to get the details of its holdings. Or you can get summary data from WIEWS. It’s actually not the only grape genebank in France, but there’s no word on overlap with other French collections, or indeed with collections in other parts of the world. Numbers vary among the sources, but this collection represents maybe half of France’s holdings of cultivated grape accessions, and a tenth of the world’s. ((Is it the ultimate source of Tahiti’s wine? No idea, but I’d like to think so.))
So it’s an important collection, large and well documented, both phenotypically and genotypically. What’s the problem? Well, the lease is running out on the land it’s been on for the past 138 years, and it needs to shift. The move will cost €4 million, and the money isn’t in the budget. INRA says it’s committed to maintaining the collection, and will find the cash. The boffins fret and worry about the disruption to research and possible losses in the process. I asked our friends at the Myles Lab in Canada for their opinion and they do see an upside:
@AgroBioDiverse @BrianFLloyd @plantbiology 1/2 The move is a good idea – offers chance to plant collection in specific experimental design

But it is worrying. We’ll keep an eye on it for you.
Brainfood: Genomics trifecta, Ex/in situ, Oat disease resistance, Drying beads, Biodiversity assessment, Maize models, Trees & nutrition, NTFP, Fortification
- Maintaining Food Value of Wild Rice (Zizania palustris L.) Using Comparative Genomics. Cultivated cultivated rice assists in the breeding of cultivated wild rice. If you see what I mean.
- Mining the Genus Solanum for Increasing Disease Resistance. The key is distinguishing the alleles from the paralogs.
- Genetic Dissection of Aluminium Tolerance in the Triticeae. And the trifecta from the Genomics of Plant Genetic Resources book. Rye has most, barley least, and we know how they do it.
- Dual Threats of Imperiled Native Agroecosystems and Climate Change to World Food Security: Genomic Perspectives. Genebanks are necessary but not sufficient.
- Identification of new sources of resistance to powdery mildew in oat. In the wild species, natch.
- Optimum ratios of zeolite seed Drying Beads® to dry rice seeds for genebank storage. 1:1 by weight.
- The Biodiversity Forecasting Toolkit: Answering the ‘how much’, ‘what’, and ‘where’ of planning for biodiversity persistence. Yeah, but will it work with agricultural biodiversity?
- How do various maize crop models vary in their responses to climate change factors? Enough to make using an ensemble best, not enough to doubt that temperature will be the main factor affecting yields by the end of the century.
- Dietary quality and tree cover in Africa. More trees, more dietary diversity, more fruit & veg consumption, though up to a point.
- The importance of local forest benefits: Economic valuation of Non-Timber Forest Products in the Eastern Arc Mountains in Tanzania. $42 million a year, spread over 2000 households.
- Fortification: new findings and implications. It’s worked in the US for some nutrients, but not for others, and in some case we don’t understand how and why. We know in other cases it is unlikely to work. Nutritionists have to work together with plant breeders. And, we would add, the agricultural sector in general.
The apple of Poland’s eye
You may have noticed a certain slackness in our blogging last week. That’s because we were both travelling for work, Jeremy holed up at an undisclosed location with lots of copy and a red pen, myself in Warsaw, trying to drum up support for genebanks. It was my first time in Poland, and much too short a visit, but I learned a lot. Like that Poland is a huge apple exporter. It also, and perhaps not coincidentally, has a lot of apple diversity, and Poles are very proud of it. Even a small corner grocery shop in Warsaw will have half a dozen and more distinct varieties on display.
That, I was told, is at least partly due to the tireless efforts of the famous apple breeder Prof. Szczepan Pieniążek, founder and long-time head of the Research Institute of Pomology in Skierniewice. The apple genebank there has maybe a thousand accessions still. Prof. Pieniążek has obviously left quite a legacy, despite being, if I understand the Google Translate rendition of his Polish Wikipedia entry, a proponent of quasi-Lamarckian theories, after the fashion of the equally famous Russian breeder Ivan Vladimirovich Michurin. I guess, in breeding, practice is much more important than theory.

- A genomic variation map provides insights into the genetic basis of cucumber domestication and diversity. Four geographic groups, bottleneck not too bad. Opportunity for breeding for better nutritional value. But I suspect that’s a low bar.
- Dietary mineral supplies in Africa. Zn seems to be the lowest hanging fruit, as it were. I wonder if above’s super-cucumbers would help.
- Mechanisms for flowering plants to benefit arthropod natural enemies of insect pests: Prospects for enhanced use in agriculture. If you chose the right plants to plant, you can boost biological control of insect pests on farms.
- Agricultural expansion and its impacts on tropical nature. Roads will lead to increased conversion of natural ecosystems to agriculture in South America and Sub-Saharan Africa. Sustainable intensification is the answer.
- From Food Insufficiency towards Trade Dependency: A Historical Analysis of Global Food Availability. If most of us have more food now, it’s because of trade.
- Technical challenges in evaluating southern China’s forage germplasm resources. Nothing they can’t handle, clearly.
- Sustaining Frafra potato (Solenostemon rotundifolius Poir.) in the food chain; current opportunities in Ghana. Better varieties and processing. Where have I heard that before? Oh yeah, in every single paper on neglected crops.
- Rayada specialty: the forgotten resource of elite features of rice. It’s a weird variant of deepwater rice from Bangladesh with possible enhanced stress tolerance due to longer root system.
- Persea schiedeana: A High Oil “Cinderella Species” Fruit with Potential for Tropical Agroforestry Systems. Superior genotypes of this neglected avocado relative identified in fairs in Mexican region, and targeted for vegetative propagation and participatory breeding.
- Quality characteristics of European avena genetic resources collections. The modern varieties are better, but that doesn’t mean the old ones are useless.
- Nutrient Intake, Morbidity and Nutritional Status of Preschool Children are Influenced by Agricultural and Dietary Diversity in Western Kenya. Low food variety is associated with stunting. Kinda sorta.
