- Constructing Seed Boundaries: Foundation and Evolution of Scientific Conceptions and Practices of Crop Diversity from the Green Revolution to date. We need to put the knowledge, expertise, activities and needs of farmers at the centre of conservation and use of crop diversity.
- Open Source Seeds and the Revitalization of Local Knowledge. Open-source seeds is one way we can put the knowledge, expertise, activities and needs of farmers at the centre of conservation and use of crop diversity.
- Evaluation of Global Composite Collection Reveals Agronomically Superior Germplasm Accessions for Chickpea Improvement. We need detailed, multi-location, multi-year agronomic evaluation of chickpea diversity to figure out what diversity we should use to give farmers the diversity we think they will need.
- Home gardens of Central Asia: Reservoirs of diversity of fruit and nut tree species. We need homegardens.
- Data-driven, participatory characterization of farmer varieties discloses teff breeding potential under current and future climates. We need detailed, multi-location, multi-year agronomic evaluation of teff diversity done in collaboration with farmers to figure out what diversity we should use to give farmers the diversity they will need, and what they already have.
- Cultural Effects on Sorghum Varieties Grown, Traits Preferred, and Seed Management Practices in Northern Ethiopia. We need detailed, multi-location, multi-year studies of farmers’ sorghum diversity, practices and needs to figure out what diversity we should use to give farmers the diversity they will need, and what they already have.
- Metrics for optimum allocation of resources on the composition and characterization of crop collections: The CIMMYT wheat collection as a proof of concept. We could use genotyping and this fancy maths to figure out what to have in our wheat genebank collections so we can then figure out which diversity to use to give farmers the diversity we think they will need.
- From marginalized to miracle: critical bioregionalism, jungle farming and the move to millets in Karnataka, India. Forget wheat. We need local food activism. But critical local food activism.
- G-DIRT: a web server for identification and removal of duplicate germplasms based on identity-by-state analysis using single nucleotide polymorphism genotyping data. We need this fancy software to get rid of duplicates from our genebank collections so it’s cheaper to maintain them and ensure that they’re always around for people to use to get to farmers the diversity they need.
- “Famine Foods” and the Values of Biodiversity Preservation in Israel-Palestine. We need recipes.
Nibbles: Food security, CWR, Rice, Food crisis, Yams, Peanuts, Tuscan wine, SADC seeds, Lonely trees
- Handy primer on the effects of climate change and biodiversity on food security, courtesy of the House of Lords.
- Crop wild relatives could help with all three.
- Trouble brewing for rice. House of Lords nodding wisely.
- The trouble that brewed for wheat wasn’t quite as advertised. Spoiler alert: the price spike had to do with China buying up all it could. So is rice next then?
- No trouble brewing for yams now that they’re getting sequenced.
- Nor for peanuts in the Gambia, for different reasons.
- Sounds like everything is hunky dory for the Tuscan grape too.
- Good to see SADC is on the job.
- It may be too late for some trees though.
After the flood
Pakistans farmers are going to need seeds after the floodwater recede. That could include local landraces, if we start planning for it now. Here’s a map of the current extent of flooding, plus the collecting localities of crop landraces conserved in genebanks around the world, according to Genesys.
Brainfood: Diversity & breeding in Coix, Triticum, Phaseolus, Manihot, Oryza, Vigna, Glycine, Zea, Malus
- Nutritional profiling and GIS-based grid mapping of Job’s tears (Coix lacryma-jobi L.) germplasm. 2 genebank accessions out of 32 are especially good.
- Diversity and Adaptation of Currently Grown Wheat Landraces and Modern Germplasm in Afghanistan, Iran, and Turkey. Some wheat landraces were just as productive as modern varieties, so crossing landraces with other landraces could be a good breeding strategy. Maybe even for Job’s tears.
- Mining of the national gene bank collection identifies resistance sources for loose smut of wheat in Northern Himalayan conditions. 58 of 586 were resistant. Let the inter-landrace crossing begin!
- Are Traditional Lima Bean (Phaseolus lunatus L.) Landraces Valuable to Cope with Climate Change? Effects of Drought on Growth and Biochemical Stress Markers. Oh no, the commercial variety is more drought-resistant than the, ahem, two landraces.
- Low-cost, handheld near-infrared spectroscopy for root dry matter content prediction in cassava. A faster and cheaper way of figuring out which cassavas are better than others.
- Mutations in DNA polymerase δ subunit 1 co-segregate with CMD2-type resistance to Cassava Mosaic Geminiviruses. Now for a faster and cheaper way of spotting the gene in your crosses.
- Phenotypic Variation and the Impact of Admixture in the Oryza rufipogon Species Complex (ORSC). Sometimes there’s no short-cut to the slog of detailed phenotyping if you want a short-cut to pre-breeding.
- Evaluation of black gram varieties using crowd source citizen science under northern hilly climatic condition of Chhattisgarh. Let the farmers do the slog of phenotyping.
- A view of the pan-genome of domesticated cowpea (Vigna unguiculata [L.] Walp.). The genes not shared by all six sub-populations of the cultivated cowpea are very important to the overall diversity of the crop. Let scientists do the slog of genotyping.
- Breeding for disease resistance in soybean: a global perspective. 800 resistance loci/alleles for 28 varied diseases from all over the world. Imagine one variety with all of them :)
- Genetic diversity in early maturity Chinese and European elite soybeans: A comparative analysis. Two equally diverse but distinct genepools. Unclear how the above 800 loci divide up.
- Association mapping across a multitude of traits collected in diverse environments in maize. More slogging through phenotyping, this time to uncover pleiotropy.
- Incorporating male sterility increases hybrid maize yield in low input African farming systems. But I guess you need the above to decide on the parents for your fancy hybrids.
- Pedigree reconstruction for triploid apple cultivars using single nucleotide polymorphism array data. Triploids apples may be bigger and stronger, but they’re also genetic dead ends.
- Evidence of an additional center of apple domestication in Iran, with contributions from the Caucasian crab apple Malus orientalis Uglitzk. to the cultivated apple gene pool. Another example of multiple domestication “events”.
Nibbles: Asian yams, Coconut survey, Belarus genebank, Jordan genebank, Tepary beans breeding, Dante’s wine
- Nice Twitter thread on Asian yams (and incidentally sweet potato and taro).
- Surveying and collecting coconuts in PNG. What will they do with those nuts?
- Belarus genebank gets a high-level visit. Can’t help wondering if the Ukraine genebank being in the news is behind this somehow.
- Jordan to get a(nother) genebank. Apparently.
- Tepary beans to get their 15 minutes of fame.
- Medieval Italian wine was biodynamic.
