The record grain outputs of India’s Green Revolution in the 1970’s established India as one of the world’s largest agricultural producers, transforming the country from a starving nation to a food exporter, creating jobs and boosting the economy. However, behind this extraordinary achievement were varying levels of success across different Indian regions, and overuse of water, fertilisers, pesticides and other chemicals on an unsustainable scale. In terms of agricultural productivity, the technologies of the Green Revolution plateaued in the 1980s, yet the continued adherence to a strategy of intensive agriculture has led to increasing pressure on water and nutrient resources.

The latest experiment before the hot summer this year were two RIL populations of groundnut, a set of selected RIL and high resolution cross of pearl millet, a set of staygreen introgression lines of sorghum, and pearl millet hybrids bred for different rainfall zones of India.

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.
