This chapter discusses the target growing environments and sensitivity of pearl millet, sorghum, maize, groundnut, chickpea and pigeon pea to drought; phenotypic screens and natural genetic variations for response to drought; empirical and trait-based breeding methods to enhance drought tolerance; and deployment of emerging biotechnological tools (DNA markers and transgene) to enhance crop adaptation and productivity under drought stress conditions.
