The major threat of the agricultural crop is the climate change, which grown globally in the subtropical and the tropical regions. Negative impact on the plant growth, development and the economic yield regarding climate change due to consequences of the draught stress. For the prediction of the climate change and occurrence of the draught many simulation models were recorded, it’s very necessary to improve the crop against the draught stress which ultimately limits the production and the productivity of the crop. Wheat crop is widely used crop because of their social and the economic values. Many country around the world which depends on the wheat crop for food as well as feed and mainly wheat are the vulnerable against the draught stress. It’s very challenging task to improve the draught stress of many researchers. The advances in the technology which ultimately gives understanding and the improvement in draught tolerance including the main three research areas viz., breeding, physiology and the genetics. When plants exposed to the draught stress the biochemical and the physiological pathways activated, the physiology focused on that research. In wheat, making the crosses through the breeding program which give the some high degree of the draught tolerance genotypes and also the many genes responsible for the draught tolerance which is identified by using the advanced biotechnological tools like QTL mapping, association mapping and GWAS technology for particular trait. In the past studies recorded, the draught tolerance shows the polygenic trait and its genetic constitution will helpful for the dissecting the gene network for controlling the draught tolerance. The presented review gives the recent advances in the main three research field for improvement of the draught tolerance in wheat.
