Genotype by Environment by Management (GxExM) Symposium IV
Event information
The ARC Centre of Excellence for Plant Success is coordinating the next Genotype by Environment by Management (GxExM) symposium on 5 and 6 November 2026 in Brisbane, Queensland and online. The symposium will focus on a range of topics related to the study of GxExM interactions and their importance for crop improvement.
The symposium will be conducted to stimulate new approaches, building on a foundation of sharing understanding and insights from case studies, leading to discussion of ideas that will advance experimental, modelling and prediction methods to enhance crop improvement strategies.
To improve accessibility for all participants, presentations will be recorded (whenever permission is granted) and made available online. If you have any questions about the format of the meeting or your potential for involvement, please contact plantsuccess@uq.edu.au.

GxExM Background
The potential importance of GxExM interactions has been considered for many performance properties of agricultural systems. There are complex and growing pressures acting upon the global crop systems on which we depend for our livelihoods.
Universally, significant yield gaps have been identified between potential and realised on-farm crop productivity for most crop systems. Further, the sustainability of the current and required levels of crop productivity to meet the expectations of future needs are continually questioned.
The challenges are diverse, complex and multi-faceted. Crop breeders seek to utilise available genetic resources to develop improved cultivars.
Crop agronomists seek to define agronomic management practices that will work for the improved cultivars.
Farmers seek to combine the improved cultivars with appropriate agronomic practices to achieve a target on-farm productivity while balancing short and long-term risks and rewards.
There have been and continue to be many calls for integrated efforts.
There are successful examples of integrated efforts between breeders, agronomists in partnership with farmers. A number of such efforts have emphasised the importance of considering the potential influences of GxExM interactions at multiple levels within the crop systems.
