Millet plays different roles in food security. It remains a staple of millions among the poorest in both India and Africa. At the same time, its growing value in the food and feed industry offers opportunities for income generation. This economic value is evident in the growth in production in both regions, even if acreage has declined. While among the staples most adapted to harsh environments, productivity gains from increased and broad stress tolerance will be significant.
The drier parts of the world are where development challenges are the greatest and market failure is most acute, and few if any of these are more urgent than the ‘Sahel’ region of Africa. Its unusual tolerance of low inputs, especially water, make the cereal crop sorghum essential to human populations in the Sahel, where episodic drought is a fact of life. Despite its importance, sorghum improvement has lagged that of maize, wheat and rice, largely if not entirely due to greater effort invested in the ‘Big Three’.
Simulation Modelling Once the reasonable depth of understanding the physiological traits is attained, ultimately, the tool for value/risk assessment of such new technology within target agro-eco-systems is necessary. Reproducing the physiological traits in silico using modelling tools enables probabilistic foresight on mechanistic of physiological traits within the framework of target agricultural production systems and so allows … Continue reading Simulation Modelling
Trait Dissection Within team activities, dissection of physiological traits lay the baseline on which all other activities are built. We focus on understanding the range of plant adaptive mechanisms underlying the crop water usage which can potentially contribute to plant production advantage in various drought stress environments. Regulated dry down Transpiration response to VPD … Continue reading Trait Dissection
Bioversity International is a global research-for-development organization that delivers scientific evidence, management practices, and policy options to use and safeguard agricultural biodiversity to attain global food and nutrition security. It works with partners in low-income countries in different regions where agricultural biodiversity can contribute to improved nutrition, resilience, productivity and climate change adaptation. Bioversity International is a member of the CGIAR, … Continue reading Alliance of Bioversity International and CIAT
Dr. Krithika Anbazhagan Krithika Anbazhagan is working with the GEMS team as a Visiting Scientist since Dec 2017. Her primary research project, in collaboration with WorldVeg, is on phenotyping elite genotypes of mungbean for drought adaptation. She is also involved and deriving mungbean crop growth parameters for crop models and farmer-participatory studies to extend relevant … Continue reading Dr Krithika – Plant Nutrition
For us gems means GEMS, or G*E*M*S (genotype by environment by management by society) interactions, i.e. the fact that crop yields results from complex biophysical interactions while acceptance depends on farmer/consumer preferences. This complexity becomes an opportunity when it is cracked into components that can be analysed, understood, predicted, and then used to prioritise research investments to maximise return. This is what we do, and this is when GEMS become gems!

A crop performs in different ways in different sites, years and agronomic managements. These are called genotype-by-environment-by management(G*E*M) interactions, and they are a main challenge for breeders and agronomists. There is one more layer of interaction, even more complex: the society (S). Farmers and consumers have different desires, needs, expectations, and a cultivar that fits one may not fit the other (G*E*M*S interactions). The puzzle is complex and challenging but if its components are understood, specific interventions can be undertaken.For instance, breeding for a particular genotype (G, with particular physiological characteristics), for a particular environment (E, with a particular kind of drought pattern that requires a specific adaptive trait), in a particular management practice (M, for instance a sowing density, or a N fertilizer treatment), and targeted to particular farmer/consumer (S, for instance a genotype that produces a lot of rich stover for cattle ranchers) is the need of the hour.
