Wheat is an important cereal crop grown worldwide primarily for chapati, bread and biscuits. Target specific wheat breeding and quality improvement programs focus on developing genetically superior, high yielding, disease resistant cultivars with desired quality that are adapted to different growth environments. Drought refers to the condition of reduced soil moisture which induces several changes in crops ., morphological, biological, physiological and molecular changes. It also causes reduction in crop yield or in some cases cause crop failure. Rain-fed areas are more likely to face such conditions. These condition leads to the financial crisis among farmers whose major occupation is agriculture. Drought effects the crops in terms of its morphology, productivity etc. The essential stages of crop growth ., vegetative and reproductive are more likely to get affected. Some plants however possess mechanisms to tolerate such conditions.
