Abstract :
The wheat production is done mostly in arid and semi-arid areas, depending on rainfall in our country. The spring wheats are exposed to high temperatures especially during anthesis and grain filling. This situation is caused a significant decrease on the yield. Climatic changes have occurred seriously in different parts of the world that are voiced by the researchers. In 2007, at the Intergovernmental Panel on Climate Change, it was reported that, the temperature rise was the main effect of will have on crop production. Climate change-induced temperature rise with all the violence continues. Consequently, potential yield losses in wheat in developing countries are expected to be around 20 to 30%. High temperature and drought, many of the world wheat mega-environment, the most important environmental factors limiting plant growth, and they occurred at the same time. Under normal circumstances, the period of wheat growth, 1°C increase on the optimum temperature values causes 57 kg ha^-1 yield loss for the spring-wheat.
