Exploring possibilities of enhancing water use efficiency in potato: A review

Abstract

Climate change threatens the global agriculture sustainability. Among different kinds of abiotic stresses, water stress is the most devastating component which curtails potato crop productivity. Our recent knowledge is limited concerning water stress tolerance and water use efficiency in potato. Many efforts are being made by the scientific community to reduce water use and to produce “more crop per drop”. This review elaborates quantitative and qualitative aspects of multiple stress mechanisms and their regulating system related to present scenario of water use efficiency (WUE) requirements. WUE can only be improved by using multidisciplinary promising research approaches like molecular breeding, high throughput genotyping, multi-gene transfer and bioinformatics applications to unleash the information needed to exploitation of required traits in potato.
