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.
