This chapter reviews the key stages in corn plant development when water deficits can most impact on productivity. It reviews progress made in genotyping and phenotyping that enable selection for improved productivity in water-limited growing conditions. Technical approaches to experimental design and data analysis that can facilitate discovery, validation, and implementation of research outputs at a commercial level are also described.
