To boost rice productivity under a changing climate

Global food demand has been rising to support future population growth under changing climates. My research interest is to increase crop yield (productivity per unit land area) in response to environmental changes, G x E interaction, using field phenotyping, crop growth model, QTL and GWAS analysis for mainly rice (Oryza sativa L.), addition to soybean and sweet potato. I want to share two topics of my current works, (1) Phenotypic plasticity: Breeding target for adapting future environments, and (2) Big data analysis: Upcycle yield trial data for future breeding.  Also, I want to introduce life in Japan.
