Salinity is a major abiotic stress that threatens crop yield and food supply in saline soil areas. Crops have evolved various strategies to facilitate survival and production of harvestable yield under salinity stress. Wheat (Triticum aestivum L.) is the main crop in arid and semiarid land areas, which are often affected by soil salinity. In this review, we summarize the conventional approaches to enhance wheat salt tolerance, including cross-breeding, exogenous application of chemical compounds, beneficial soil microorganisms, and transgenic engineering. We also propose several new breeding techniques for increasing salt tolerance in wheat, such as identifying new quantitative trait loci or genes related to salt tolerance, gene stacking and multiple genome editing, and wheat wild relatives and orphan crops domestication. The challenges and possible countermeasures in enhancing wheat salinity tolerance are also discussed.

提高盐碱农业的小麦耐盐性

盐度是一种主要的非生物胁迫,威胁着盐渍土地区的作物产量和食物供应。作物已经进化出各种策略来促进盐胁迫下的生存和可收获产量的生产。小麦(小麦L.)是干旱和半干旱地区的主要作物,这些地区经常受到土壤盐分的影响。在这篇综述中,我们总结了提高小麦耐盐性的常规方法,包括杂交育种、化合物外源施用、有益土壤微生物和转基因工程。我们还提出了几种提高小麦耐盐性的新育种技术,例如鉴定与耐盐性相关的新数量性状位点或基因、基因堆叠和多基因组编辑,以及小麦野生近缘种和孤儿作物驯化。还讨论了提高小麦耐盐性的挑战和可能的对策。
