干旱是限制全球作物生产力和产量稳定性的主要环境压力。提高农作物的抗旱性被认为是在可用水量减少的情况下提高农业生产力的可持续且经济可行的解决方案。该解决方案的实施需要广泛探索潜在的遗传资源并深入了解其适应机制和对缺水的反应。在这篇小综述中，我们总结了野生二粒小麦 [Triticum turgidum ssp.] 抗旱性的生理、生态和遗传方面。 dicoccoides (Korn.) Thell.] 并讨论它们对小麦改良的影响。对以色列整个干旱梯度范围内收集的野生二粒小麦种群进行的全面调查显示，干旱反应具有广泛的遗传多样性，相当多的野生品种表现出优于硬质小麦品种的优势。与改善表现相关的各种适应性特征...
Drought is the main environmental stress limiting crop productivity and yield stability worldwide. Improving drought resistance of crop plants is considered a sustainable and economically viable solution to increasing agricultural productivity under diminishing water availability. The implementation of this solution requires wide explorations of potential genetic resources and in-depth understanding of their adaptive mechanisms and responses to water deficit. In this minireview we summarize the physiological, ecological, and genetic aspects of drought resistance in wild emmer wheat [Triticum turgidum ssp. dicoccoides (Korn.) Thell.] and discuss their implications on wheat improvement. A comprehensive survey of wild emmer wheat populations, collected across the aridity gradient in Israel, revealed wide genetic diversity for drought responses, with a considerable number of wild accessions exhibiting an advantage over durum wheat cultivars. A variety of adaptive traits associated with improved performances u...
