- Genetic structure and diversity of India hybrid tea. It’s complicated. It’s important because the success of tea outside its core are is due to hybridization between Indian and Chinese types in Assam starting in 1875. It’s limited.
- NGS technologies for analyzing germplasm diversity in genebanks. That’s Next-Generation Sequencing. Can be used to “identify patterns of genetic diversity, map quantitative traits and mine novel alleles.” Recommendation is for “genotyping by sequencing” to be applied stepwise, starting with a core collection. That’ll be complicated, but the real bottleneck will be the phenotyping.
- The role and influence of grandmothers on child nutrition: culturally designated advisors and caregivers. Wise up, nutrition advocates. You are, apparently, ignoring egg-suckers, a primary force for good.
- The importance of eating local: slaughter and scurvy in Antarctic cuisine. Who needs oranges when you have fresh penguin at hand?
- Islands and streams: clusters and gene flow in wild barley populations from the Levant. There is ecogeographic patterning in the wild material, once you remove the effect of recent admixture with cultivated barley. Geneflow is more N to S than vice versa.
- Global change belowground: impacts of elevated CO2, nitrogen, and summer drought on soil food webs and biodiversity. It’s complex, really complex; increased CO2 and N may result in new, simpler belowground assemblages.

A Green Revolution for trees
Prof Roger Leakey, sometime of ICRAF (among other places), where he pioneered tree domestication in support of rural livelihoods, and now Vice Chairman of the International Tree Foundation, has a fascinating new book in the offing.
In contrast to the doom and gloom often emanating from the tropics, ‘Living with the Trees of Life’ illustrates how many different aspects of agricultural science can be combined into a more robust approach to farming, which will be productive, as well as more environmentally and socially sustainable. This approach uses agroforestry as a delivery mechanism for multifunctional agriculture aimed at addressing the cycle of land degradation and social deprivation in the tropics. A key role in this is played by the ‘Trees of Life’, the large number of indigenous trees that produce marketable fruits, nuts, medicines and other products of day-to-day importance in the lives of local people throughout the tropics.
The book promises to be very practical.
A 3-step approach is described which can be used to close the Yield Gap (the difference between the yield potential of food crops and the yields actually achieved by farmers). This pays special attention to land husbandry and to the wise use of the natural resources which support agriculture and the livelihoods of poor farmers. By closing the Yield Gap agroforestry builds on the advances of the Green Revolution.
Builds on those advances while avoiding its pitfalls, and indeed rectifying its more regrettable consequences, one assumes.
Finally, all this comes together in a set of five ‘Convenient Truths’ which highlight that we have most of the knowledge and skills we need. This is illustrated by the Equator Prize winning project ‘Food for Progress’, in Cameroon, a project which has also been recognized by UK Government’s Office for Science as an African Success Story.
I had a little trouble identifying this project, but I believe I finally found it, and very interesting it sounds too.
Look out for the book in July, from CABI.
Featured: Lathyrus
This is just a teaser, the start of a long and interesting comment on grasspea from Fernand Lambein, a Belgian scientist.
I respect the authors for trying to put new live into Lathyrus sativus research and for questioning why two generations of efforts did not result in what has been achieved in other crops.
Don’t just take our word for it. Read the whole thing, and be amazed at how useful grasspea can really be.
Fire at the Filipino genebank
We have received sad news of a fire at the national genebank in the Philippines, the same one which featured in the news item we nibbled yesterday about the much-needed refurbishments it is undergoing. More details as we get them. If you have any information, let us know.
Any crops, or crop wild relatives, in the eastern Andes?
Well, of course there are. I mean, there must be. But we can’t be sure, at least not as far as this paper in BMC ecology is concerned. The abstract of Plant and animal endemism in the eastern Andean slope: Challenges to conservation tells us that “The Andes-Amazon basin of Peru and Bolivia is one of the most data-poor, biologically rich, and rapidly changing areas of the world” and goes on to say that the scientists “mapped ecological systems, endemic species concentrations, and irreplaceable areas with respect to national level protected areas”. It concludes:
We found that many endemic species and ecological systems are lacking national-level protection; a third of endemic species have distributions completely outside of national protected areas. Protected areas cover only 20% of areas of high endemism and 20% of irreplaceable areas. Almost 40% of the 91 ecological systems are in serious need of protection (=< 2% of their ranges protected).
Are any of the plants they studied wild relatives of crops? How about actual crops? Anyone able to comment?
