This project aims to address significant gaps in our understanding of mungbean yield including: what determines yield in mungbeans and what are the constraints that limit yield performance under optimal and sub-optimal (heat / water stress) conditions and why different genotypes have higher yields than others and dynamics of harvest index in mungbean. In addition, field data will be used to calibrate the APSIM mungbean model. This project focuses on optimising breeding and management strategies to increase grain yield and crop resilience in mungbean for the benefit of growers and the broader industry.
