Pigeon Foot sorghum unmasked
You may remember my quandary over the meaning of the name of the sorghum variety Gadam El Hamam. Well, I had the opportunity of asking real experts at the ICRISAT office in Nairobi yesterday. They confirmed, first of all, that the Gadam sorghum that is being so successfully used in beer brewing in Kenya is indeed a selection from the Sudanese variety Gadam El Hamam. And after a quick email to their Sudanese sorghum breeder colleague based in Addis Ababa, we solved the mystery of the name. It turns out the correct transliteration is Gadam Elhmam, which means “Pigeon Foot” in Arabic. This is apparently a trope that is used in Sudanese poetry and songs to describe a beautiful lady. So I more or less had the bits, but I could not put them together. Thanks to all at ICRISAT in Nairobi for helping me do that at last.
Incidentally, the photo is of a beautiful Faidherbia albida tree on the ICRAF campus in Nairobi, which is where the ICRISAT regional office is housed. You may be able to make out from that the Napier grass and mulberries are taller and more lush just under the tree as compared to further back. They don’t call Faidherbia the cornerstone of “evergreen agriculture” (big PDF) for nothing.
The Queen of Crop Breeding
Yes, I know blogging has been slow the past week or so, but I’ve been on leave and Jeremy way too busy with work for everyone’s good, though mostly his. But look, you got couple of big fat Brainfoods to keep you going, no? 1 Anyway, thought you might be interested in this piece in Kenya’s Saturday Nation newspaper a couple of days back. It’s a profile of AGRA plant breeder Dr Jane Ininda. The illustration is a (poor quality, alas) photo of the actual newspaper, which I took because it was such a treat to see a crop breeder splashed all over a major national newspaper. And the effect is just not the same in the digital version.
Brainfood: Ethiopian coffee, Kenyan climate change, Biofortification, Pasture legume adoption, Moroccan veggies, Economics of pests, Grassland diversity & fire, Seed storage, Resistant beans, Maize OPVs, Low P tolerance in NERICA, Brazilian beans
- Prospects for forest-based ecosystem services in forest-coffee mosaics as forest loss continues in southwestern Ethiopia. Coffee agroforests provide about half to two thirds of the ecosystem services of plain old forests.

- Bioavailability of iron, zinc, and provitamin A carotenoids in biofortified staple crops. Focus on breeding varieties with elevated micronutrient concentrations is justified. Phew.
- The future of warm-season, tropical and subtropical forage legumes in sustainable pastures and rangelands. Those who cannot remember the past are condemned to repeat it. And the past, in this case, was full of mistakes.
- Wild leafy vegetable use and knowledge across multiple sites in Morocco: a case study for transmission of local knowledge? The Rif Mts are a hotspot of weed diversity. Not that kind of weed, settle down. No, wait…
- Agricultural Trade, Biodiversity Effects and Food Price Volatility. Pests are damaging to neat economic models. Pesticides fix that but damage the environment. No word on the economics of natural enemies, integrated pest management, varietal diversity etc.
- Annual burning drives plant communities in remnant grassland ecological networks in an afforested landscape. In the southern Afromontane region, annual burning does not reduce the species diversity of grassland patches, but does make these patches look more and more alike. Add heavy cattle grazing though and that does reduce diversity.
- Responses to fire differ between South African and North American grassland communities. Decreasing fire frequency increased species diversity in Kansas, decreased it in Kwa-Zulu Natal. It’s because of the rhizomatous species in America. What does this and above mean for crop wild relatives?
- Prolonging the longevity of ex situ conserved seeds by storage under anoxia. Remove oxygen to make seeds last longer in genebanks.
- Identification of Sources of Bacterial Wilt Resistance in Common Beans (Phaseolus vulgaris L.). Only 1 resistant accession out of 500 in the USDA collection. And it’s a wild one.
- Evaluation of Evolution and Diversity of Maize Open-Pollinated Varieties Cultivated under Contrasted Environmental and Farmers’ Selection Pressures: A Phenotypical Approach. OPVs are diverse and change over time. Still no cure for cancer.
- A novel allele of the P-starvation tolerance gene OsPSTOL1 from African rice (Oryza glaberrima Steud) and its distribution in the genus Oryza. Kasalath comes to the rescue of NERICA. Must be the only sativa gene NOT in NERICA.
- Agronomic potential of genebank landrace elite accessions for common bean genetic breeding. Yeah, but are they in the Brazilian genebank? Doesn’t look like it.
