Potato (Solanum tuberosum L.) is often considered as a drought sensitive crop and its sustainable production is threatened due to frequent drought episodes. There has been much research aiming to understand the physiological, biochemical, and genetic basis of drought tolerance in potato as a basis for improving production under drought conditions. The complex phenotypic response of potato plants to drought is conditioned by the interactive effects of the plant's genotypic potential, developmental stage, and environment. Effective crop improvement for drought tolerance will require the pyramiding of many disparate characters, with different combinations being appropriate for different growing environments. An understanding of the interaction between below ground water uptake by the roots and above ground water loss from the shoot system is essential. The development of high throughput precision phenotyping platforms is providing an exciting new tool for precision screening, which, with the incorporation of innovative screening strategies, can aid the selection and pyramiding of drought-related genes appropriate for specific environments. Outcomes from genomics, proteomics, metabolomics, and bioengineering advances will undoubtedly compliment conventional breeding strategies and presents an alternative route toward development of drought tolerant potatoes. This review presents an overview of past research activity, highlighting recent advances with examples from other crops and suggesting future research directions.
马铃薯（Solanum tuberosum L.）通常被认为是一种对干旱敏感的作物，由于干旱频发，其可持续生产受到威胁。已有许多研究旨在了解马铃薯耐旱性的生理、生化和遗传基础，作为在干旱条件下提高产量的依据。马铃薯植株对干旱的复杂表型反应受植物基因型潜力、发育阶段和环境的交互作用影响。有效的耐旱作物改良需要将许多不同的性状进行聚合，不同的组合适用于不同的生长环境。了解根系地下吸水与地上茎叶系统水分散失之间的相互作用至关重要。高通量精准表型分析平台的发展为精准筛选提供了一种令人兴奋的新工具，结合创新的筛选策略，可有助于选择和聚合适合特定环境的耐旱相关基因。基因组学、蛋白质组学、代谢组学和生物工程进展的成果无疑将补充传统育种策略，并为培育耐旱马铃薯提供一条替代途径。本综述概述了过去的研究活动，突出了其他作物的最新进展，并提出了未来的研究方向。
