- 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.
Organic breeding conferences
The European Consortium for Organic Plant Breeding (ECO-PB) has announced two up-coming meetings. One is dedicated to the European organic seed regime and the other one is a celebration of ECO-PB’s 10 year anniversary.
The Workshop on Organic Seed Regulation will take place at The Organic Research Centre near Newbury in England on 21-22 September 2011.
The 10-year shindig is scheduled for 3-4 November 2011 in Frankfurt am Main, Germany. That one has a call for papers, due by 15 June 2011.
ECO-PB is having a little trouble making the documents available at its website. As a service, here they are.
If you go, consider blogging for us.
Brainfood: Millet biscuits, Wheat micronutrients, Diversification and C footprint, Agroforestry, Epazote, Grape history, Belgian farmers, Millet phenology, Species migration, Barley domestication, Sheep genetics
- Quality characteristics of biscuits prepared from finger millet seed coat based composite flour. They’re nutritious. Crocodile Dundee on the tastiness of the iguana may, however, apply.
- Minerals and trace elements in a collection of wheat landraces from the Canary Islands. There are differences, but environment and agronomic practices could affect them.
- Lowering carbon footprint of durum wheat by diversifying cropping systems. Yes, by 7-34%, depending on how the diversification was done.
- Effect of shading by baobab (Adansonia digitata) and néré (Parkia biglobosa) on yields of millet (Pennisetum glaucum) and taro (Colocasia esculenta) in parkland systems in Burkina Faso, West Africa. Taro is a shade lover; grow it under néré, and vice versa.
- Ethnobotanical, morphological, phytochemical and molecular evidence for the incipient domestication of Epazote (Chenopodium ambrosioides L.: Chenopodiaceae) in a semi-arid region of Mexico. Good to know; I love epazote.
- Grape varieties (Vitis vinifera L.) from the Balearic Islands: genetic characterization and relationship with Iberian Peninsula and Mediterranean Basin. See the grand sweep of European history unfold.
- Microsatellite characterization of grapevine (Vitis vinifera L.) genetic diversity in Asturias (Northern Spain). No evidence of communication with the previous group.
- Plant economy of the first farmers of central Belgium (Linearbandkeramik, 5200–5000 b.c.). They were dope fiends.
- Selection for earlier flowering crop associated with climatic variations in the Sahel. Compared to 1976 millet samples, samples collected in 2003 had shorter lifecycle (due to an early flowering allele at the PHYC locus increasing in frequency), and a reduction in plant and spike size. So you don’t need new varieties, the old ones will adapt to climate change. Oh, and BTW, there’s been no genetic erosion.
- Do species’ traits predict recent shifts at expanding range edges? No.
- The domestication syndrome genes responsible for the major changes in plant form in the Triticeae crops. Failure to disarticulate and 6-rows in barley, in detail. Part of a Special Issue on Barley.
- The genetics of colour in fat-tailed sheep: a review. I didn’t know karakul had fat tails.
Diverse lawns are smarter lawns
There’s been a lot of talk lately about the demise of the Great American Lawn. Or at least its metamorphosis into something a little more sustainable. Even the White House lawn is not immune to re-development. But a recent post on the Native Plants mailing list of the Plant Conservation Alliance points to what may be the beginnings of a backlash. Here’s what Mark Simmons had to say in response to an article in the Star Tribune entitled Goodbye to Grass (Mark’s comments are reproduced here with his permission):
I really like my lawn – my low maintenance, species-rich, drought-adapted native lawn.
While I agree that lawns can be replaced with alternative vegetation, I think that the lawn is entitled to a place in the American landscape and we should be careful of following the current fashion of demonizing turf. It’s not the lawn that’s the problem is how lawns are manufactured. We take a usually single non-native species that’s been bred to rely on a life-support system of water, fertilizer, pesticides herbicides, and a crazy mowing regimen. If you look at native short grasslands around the world its clear that, in contrast, they are low nutrient, species-rich, systems which are at ecological quasi-equilibrium usually maintained by grazing and or fire. Here at the Lady Bird Johnson Wildflower Center we adopted an ecological approach to turf by testing different mixes of native turf grasses and against a commonly-used non-native turf lawn species (bermudagrass) and measured performance. The multispecies native mix needs less mowing, had less weeds and was a denser, finer (better looking) turf. The results were just published in the journal Ecological Engineering. Sure it can go drought-dormant and brown in summer if it’s not watered. But if that may be an acceptable alternative to no lawn at all.
My young children can’t play baseball in gravel and agaves. And I want to sink a beer on a Saturday evening bare foot in soft, cool turf. Let’s keep doing lawns, just do them smart.

- Farming for balanced nutrition: an agricultural approach to addressing micronutrient deficiency among the vulnerable poor in Africa. Dietary diversity is a good idea for many reasons.
- Cultivar characterization of Aegean olive oils with respect to their volatile compounds. Only two varieties, and they do differ.
- Beef Authentication and Retrospective Dietary Verification Using Stable Isotope Ratio Analysis of Bovine Muscle and Tail Hair. Back40 has an explanation of why this is more important than all the certification schemes in the world.
- Promoting native trees in shade coffee plantations of southern India: comparison of growth rates with the exotic Grevillea robusta. Some native species might be able to compete, more research needed.
- Regeneration of Vitellaria paradoxa and Parkia biglobosa in a parkland in Southern Burkina Faso. Vitellaria doing better, possibly because farmers are overharvesting Parkia seeds.
- Defining the poor by the rural communities of Burkina Faso: implications for the development of sustainable parkland management. It’s complicated.
- Does soil biota benefit from organic farming in complex vs. simple landscapes? Organic farming increases weed diversity. No word on what it does for birds, but…
- Species richness and composition of bird communities in various field margins of Poland. Some types of field margins are better than others. No word on what they do for weeds.
