Wheat (Triticum aestivum L.) contributes substantially to global food and nutritional security. With the growing demands under the constraints of depleting natural resources, environmental fluctuation, and increased risk of epidemic outbreaks, the task of increasing wheat production has become daunting. The factors responsible for first green revolution seem to be exhausting rapidly, and there is an immediate need to develop the technologies which can not only increase the wheat production but also sustain the same at a higher level without adversely affecting the natural resources. Understanding abiotic stress factors such as temperature, drought tolerance, and biotic stress tolerance traits such as insect pest and pathogen resistance in combination with high yield in plants is of paramount importance to counter climate change related adverse effects on the productivity of wheat crops. Thus, an important goal of wheat breeding is to develop high-yielding varieties with better nutritional quality and resistance to major diseases. Therefore, in this chapter, we present a judicious mixture of basic as well as applied research outlooks. We trust that the information covered in this chapter would bridge the much-researched area of stress in plants with the information to breed climate-ready crop cultivars to ensure food security in the future.
小麦(Triticum aestivum L.)对全球粮食和营养安全做出了重大贡献。在自然资源日益枯竭、环境波动以及疫情爆发风险增加的限制下,随着需求的不断增长,提高小麦产量的任务变得艰巨。引发第一次绿色革命的因素似乎正在迅速耗尽,迫切需要开发不仅能提高小麦产量,还能在不负面影响自然资源的情况下将产量维持在更高水平的技术。了解非生物胁迫因素,如温度、耐旱性,以及生物胁迫耐受性特征,如对害虫和病原体的抗性,并结合植物的高产特性,对于应对气候变化对小麦作物生产力的相关不利影响至关重要。因此,小麦育种的一个重要目标是培育出具有更好营养品质和对主要病害有抗性的高产品种。因此,在本章中,我们展示了基础研究和应用研究前景的明智结合。我们相信,本章涵盖的信息将把植物胁迫这一研究充分的领域与培育适应气候变化的作物品种的信息联系起来,以确保未来的粮食安全。
