Literature is flooded with reports on plant phenotypes which could potentially enhance plant adaptation to limited-water-supply environments. However, very few of these phenotypes are being practically used as selection criteria in crop improvement programmes. Part of the reason for this discrepancy is that 1) the phenotype doesn’t improve the crop production significantly 2) the phenotype … Continue reading Phenotype Variability => Phenotype Value
Why is it important? Lysimetric approach- the innovation How it works Importance to crop improvement Uniqueness of the facility and relevance to other locations Re-constructing the drought puzzle The two different angles this research led to Further Why is it important? Phenotyping, or measuring key traits of crops such as drought-tolerance, is crucial in … Continue reading Lysimetric Facility
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 Plant … Continue reading Trait Dissection
Phenotyping After the given plant phenotype is reasonably understood and the potential economic value of the phenotype assessed in silico, ultimately, the tools enabling massive screening of such phenotype is inevitable to assist the breeding programs. To encounter the typical breeding population size and screen for the phenotype relevant for crop production improvement in target … Continue reading Phenotyping
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.
