- Alien introgressions represent a rich source of genes for crop improvement. Polyploids such as wheat do it best.
- Characterization of sorghum genotypes for traits related to drought tolerance. There is diversity within the “association panel” of diverse germplasm used. What I want to know is how that is different from a core or mini-core collection.
- Rice near-isogenic-lines (NILs) contrasting for grain yield under lowland drought stress. Small genetic differences can lead to big differences in yield under drought stress. What I want to know is whether doing this on NILs is better value for money than doing it on association panels of germplasm (see above), whatever they may be.
- Towards better tasting and more nutritious carrots: Carotenoid and sugar content variation in carrot genetic resources. European accessions sweeter and more orange than Asian.
- Changes in duration of developmental phases of durum wheat caused by breeding in Spain and Italy during the 20th century and its impact on yield. Fascinating unpicking of just where the genetic changes have their impact.
- Legume genetic resources: management, diversity assessment, and utilization in crop improvement. A lot of characterization, not enough evaluation. Core collections useful, but not useful enough. Crop wild relatives being used, but not enough. Good plug for the importance of geo-referencing.
- Genetic diversity and geographical peculiarity of Tibetan wild soybean (Glycine soja). Low and high, respectively.
- Analysis of agricultural production instability in the Gezira Scheme. Went up for wheat, cotton and sorghum, down for groundnuts, on liberalization.
- Biochar effects on soil biota – A review. It’s complicated but, on the whole, not unpositive.
- A research agenda to explore the role of conservation agriculture in African smallholder farming systems. Basically, it is likely to work least well in marginal conditions. Which is kinda surprising, and not, at the same time.
- Ecotypes of European grass species respond differently to warming and extreme drought. Yeah, but, alas, not in the way one might have wished.
- Comparison of nutritional quality of the crops grown in an organic and conventional fertilized soil. Maybe lower nitrate and N, higher P in organic crops. But really too much variation to be sure.

Earth Microbiome Project sets an example
Is there any good reason why we should not do this with agrobiodiversity, starting with crops and their wild relatives? In fact, is there any good reason why we have not done it already?
