Wheat is considered as a major staple food crop in the world that fulfil the nutritional requirement of people globally. Since ages, wheat production has been providing nutritional security to people all around the world. But there are several factors that hinders the production of wheat and abiotic stress is one of them. This article is a review of abiotic stress that leads into several physiological, morphological and biochemical alterations in wheat. Abiotic stress is environmental condition that reduces growth and yield of plant below optimum level. Drought, salt, heat, wind is the major abiotic stress that adversely affect plant growth and productivity. These stress alone or in combined form can pose a serious intimidation on the wheat production. Delayed germination, decreased net photosynthetic rate, plant stunting, water and nutrient stress, reduced tillering and number of spikelets, lower grain test weight and low grain yield are the consequences of abiotic stress in wheat. Some of the wheat varieties are found to be highly tolerant to this abiotic stress while some are sensitive to these stresses. Stress resistance superior wheat genotypes with suitable agronomic management and scheduling is found to be the ultimate solution to this abiotic stress.
