Drought stress and wheat (Triticum aestivum L.) yield: A review
Akshay Kumar Rawtiya and Yuvraj Gopinath Kasal
The planet is facing the challenge of drought as a result of changing climate patterns. Drought is becoming a serious downside for wheat production because major wheat-producing countries are located in drier parts of the world and depend on monsoon rain for wheat cultivation. In this study, previous works were assessed to explore the effects of drought stress on wheat yield and yield-attributing characters. The plant alters its physio-chemical state. Plant height, spike length, number of spikes per unit area, number of spikelets/spike, number of grains/spike, biomass yield, harvest index, test weight, and other yield-attributing characters are all affected by moisture deficiency are impacted, resulting in a reduction in grain yield. The degree of yield loss varies by genotype and crop development stage, and is influenced by a variety of soil, plant, and environmental conditions. Drought stress and its effects are not only a concern of agronomists, but also of plant breeders, due to the relationship between yield and genetic make-up of the crop. Wheat is the foundation of many food and feed industries, so increasing wheat production is essential for the long-term survival of the world's population. The article focuses solely on the effects of drought on yield and yield-attributing factors, as this is a key problem among modern breeders and world leaders.
