- Genomic variation in tomato, from wild ancestors to contemporary breeding accessions. A first domestication in South America, a second step in Mesoamerica, occasional hybridization in the wild, differentiation through human selection. Some Ecuadorian and Peruvian diversity still unexplored for breeding.
- Characterization of a collection of local varieties of tomato (Solanum lycopersicum L.) using conventional descriptors and the high-throughput phenomics tool Tomato Analyzer. Instant gratification comes to tomato characterization.
- Molecular diversity and genetic structure of 380 sweetpotato accessions as revealed by SSR markers. Also a two-step domestication history? What are the odds?

- Genetic Diversity Among the Microorganisms in Daqu Used for Beidacang Liquor as Revealed by RAPD Analyses. Well that’s a new one on me, but it’s good to have the data.
- Farm animal genetic and genomic resources from an agroecological perspective. If you’re going to really be ecological in your management of livestock genetic resources, you need to factor in ecosystem services, and figure out how genomic tools are going to help you. Well, that pretty much goes for crops too, surely.

Promoting the sweet potato in Africa
Good to see the March edition of Hortinews magazine focusing on the sweetpotato in Africa. 1 I found it a little difficult to navigate the feature online, although you can also just download the whole issue as a pdf, so let me link directly to two stories on orange-fleshed sweetpotatoes (OFSP):
- Shaping up the orange-fleshed sweetpotato: Shamba Shape Up programme aired 8 episodes about the orange-fleshed sweetpotato, focusing on planting, diseases, storage, cuttings, vine health and cooking on Citizen TV.
- Nutritional analysis is critical to the development of OFSP in SSA: CIP advocated for increased nutrition related research at BecA-ILRI to meet the growing demand for quality nutritional analysis.
Now, a lot of effort has gone into developing and disseminating OFSP in parts of Africa, and their potential importance in addressing vitamin A deficiency is not disputed. However, not everything has gone totally smoothly. As an IDS report, coincidentally also just out, points out:
Donor-funded initiatives have played a central role in developing all stages of the OFSP value chain, with a particular focus on breeding new varieties that appeal to the preferences of both producers and consumers. Development projects have also supported the dissemination of planting materials and funded public awareness campaigns. However, information collected for this case study suggests that, so far, interventions have not achieved widespread uptake of OFSP. Only a small minority of farming households in intervention districts grow OFSP. 2 Commercial farmers who supplied OFSP planting materials to project distribution systems have found that, after project funding ended, the local market was not viable, and have ceased production. Meanwhile, awareness of and demand for the crop among consumers have been very limited; one survey conducted in an intervention district found that only 2 per cent of households consumed OFSP. Traders and food processors report that there is little demand, and dealing with the crop is not profitable. This state is perhaps unsurprising given that the introduction of OFSP is still relatively recent, that project efforts have been relatively scattered and uncoordinated, and that there has been little focus on commercially viable value chains. Yet the challenges encountered in Tanzania provide important lessons for other agriculture-nutrition initiatives.
But no need to panic, all is not lost. It’s still relatively early days yet, and the report also makes some sensible recommendations to turbo-charge adoption:
I think it would have been useful, as well as fair, for Hortinews to point out what still needs to be done, as well as what has been achieved. But maybe that doesn’t sell glossy magazines.
Brainfood: Spanish sheep, Chicory diversity, Sweetpotato GMO, Wild sweetpotato gaps, Diverse grassland, Sorghum nutrition, Diverse agriculture, Diverse farmland, Medicinal fungus, Colombian olives, Citrus phylogeny
- The biodiversity and genetic structure of Balearic sheep breeds. 5 types, pretty well differentiated among themselves, and very different to the mainland breeds.
- Exploration of genetic diversity within Cichorium endivia and Cichorium intybus with focus on the gene pool of industrial chicory. Species reasonably, though not completely, differentiated. C. intybus division into 3 phenotypic cultivar groups (Witloof, root chicory and leaf chicory) confirmed. Leaf chicory division into 3 phenotypic subgroups confirmed (Radicchio, Sugarloaf and Catalogne cultivars). Modern industrial root cultivars have high phenotypic and genetic variability.
- The genome of cultivated sweet potato contains Agrobacterium T-DNAs with expressed genes: An example of a naturally transgenic food crop. No doubt it will soon be banned in Europe.
- Distributions, ex situ conservation priorities, and genetic resource potential of crop wild relatives of sweetpotato [Ipomoea batatas (L.) Lam., I. series Batatas]. 79% of species identified as high priority for further collecting. None of them GMOs. Yucatan is the place to go to get bang for buck.
- Complementary effects of species and genetic diversity on productivity and stability of sown grasslands. Species diversity increased productivity under drought, regardless of number of genotypes per species present. Genotypic diversity increased temporal stability of production under both drought and non-drought conditions, regardless of number of species.
- Exploiting Nutritional Value of Staple Foods in the World’s Semi-Arid Areas: Risks, Benefits, Challenges and Opportunities of Sorghum. Unbalanced amino acid composition, cyanogenic glycosides and antinutrients are obstacles to increased consumption, but can be overcome by: reduction of worrisome components (or their activity), good practices to minimise contamination and compensation by varied diet.
- Nutritional and Health Implications of Conventional Agriculture — A review. Only agricultural biodiversity can save us.
- Pollination services from field-scale agricultural diversification may be context-dependent. Hedgerows may not always be good for both crop pollination and wild bee conservation.
- Morphological, Physiological and Molecular studies on wildly collected Cordyceps militaris from North West Himalayas, India. You can cultivate it.
- Olive biodiversity in Colombia. A molecular study of local germplasm. 5 of the genotypes could not be identified with known varieties.
- A phylogenetic analysis of 34 chloroplast genomes elucidates the relationships between wild and domestic species within the genus Citrus. 3 main clades: citron/Australian species, pummelo/micrantha and papeda/mandarins. Lots of heteroplasy. 4 genes showing positive selection.
