Grain legumes being affordable sources of proteins, vitamins and essential micronutrients are key to human nutrition worldwide. However, frequent drought episodes present serious threat to grain legume production worldwide. Advances in legume omics in concert with evolving phenotyping and breeding techniques hold great promise to improve drought response of these crops. These resources could underpin prebreeding efforts to expedite discovery and deployment of novel drought tolerance traits into elite backgrounds. Fast‐track transfer of traits that confer drought tolerance using marker technologies has been demonstrated in grain legumes like chickpea. However, complex genetic architecture of drought tolerance demands embracing more efficient tools like genomic selection (GS) for accelerated trait improvement. Recent studies on GS for addressing complex traits like drought tolerance have yielded encouraging results in these crops. Recently, speed breeding (SB) protocols have also been optimized for the improvement of long‐day/day‐neutral grain legumes. Efficacy of SB protocols with regard to complex traits awaits further evidences though. There remains immense scope for integrating SB with GS and gene editing to deliver drought‐tolerant cultivars.

解决谷物豆科植物干旱胁迫的“组学”方法的进展

谷物豆类是可负担的蛋白质，维生素和必需微量营养素的来源，是全球人类营养的关键。然而，频繁的干旱事件严重威胁着全球谷物豆类的生产。与不断发展的表型和育种技术相结合，豆科组学的进步为改善这些作物的干旱响应提供了广阔的前景。这些资源可以为加快新发现的耐旱性状的发现和推广到优良背景中提供基础。在鹰嘴豆等豆类谷物中已证明使用标记技术可以快速转移赋予耐旱性状的性状。但是，复杂的抗旱基因结构要求采用更有效的工具，例如基因组选择（GS），以加速性状的改善。GS在解决诸如耐旱等复杂性状方面的最新研究在这些作物上取得了令人鼓舞的结果。最近，速育（SB）协议也已进行了优化，以改善长日/日中性谷物豆类。SB协议对于复杂特征的功效尚待进一步的证据。将SB与GS整合以及基因编辑以提供耐旱品种仍然存在巨大的空间。
