Free the grasspea

Is there a valid scientific reason for the grasspea (Lathyrus sativus) ban in India? We’ve blogged about this before. Mongabay is now on the case.

The claim that khesari dal can cause lathyrism is increasingly being challenged by researchers who feel that the ban was not based on systemic research over a prolonged period.

So what’s the problem?

Sources in the FSSAI ¹ say that the ban has helped people associated with the import of other pulses such as toor dal ². “In the wake of drop in production of popular pulses ensuing imports, traders lobby is benefitted. (Shortage of pulses in India, increases prices, benefitting traders.) They would never want the ban lifted,” said one official on condition of anonymity.

Meanwhile, research and breeding continue.

Indigenous Grasses for Rehabilitating Degraded African Drylands. Promising results, but it’s not easy.
Variability in the Global Proso Millet (Panicum miliaceum L.) Germplasm Collection Conserved at the ICRISAT Genebank. Asian, European and mixed clusters, based on morphology. Out of over 800 accessions, 3 (IPm 2069, IPm 2076 and IPm 2537) are rich in grain Fe, Zn, Ca, and protein.

The genome of cowpea (Vigna unguiculata [L.] Walp.). There’s a gene for multiple organ gigantism.
Reduced response diversity does not negatively impact wheat climate resilience. The suggestion that the statistical methods used were faulty means wheat may not be as in trouble in Europe as a previous paper suggested.
Evaluating WorldClim Version 1 (1961–1990) as the Baseline for Sustainable Use of Forest and Environmental Resources in a Changing Climate. Maybe not as good as it might be. But what’s the alternative?

Global mapping of cost‐effective microalgal biofuel production areas with minimal environmental impact. The dry coasts of N and E Africa, the Middle East, and western S America. But how minimal is minimal?

Genetic association with high‐resolution climate data reveals selection footprints in the genomes of barley landraces across the Iberian Peninsula. Cold temperature, late‐season frost occurrence and water availability have driven landrace genetic differentiation.
