Wheat is one of the most important products that is accepted as a primary indicator in the monitoring of hunger worldwide and it is a necessity to ensure that the amount of wheat production meets the needs of the increasing population. This study aims to reveal the relationship between meteorological factors and yields of wheat varieties grown in dry conditions in Sanliurfa Ceylanpinar region by growth periods and develop variety-based yield estimation models. In the research, wheat growth periods have been determined as Establishment, Tillering, Head Development, Flowering, Yield Formation and Ripening, and the average vegetation period together with Winter Dormancy was determined as 235 days. Pandas, Firat-93, Pehlivan and Cesit-1252, which are some of the most cultivated wheat varieties in the region during the research period, were included in the subject of the study. In the study, it was determined that vegetation period rainfall (r=0.74 and r=0.73, respectively) in Pandas and Firat-93 varieties, average wind speed (r=0.74) in Pehlivan variety and Establishment period rainfall (r=0.88) in Cesit-1252 varieties were the most effective variables on yields. Besides, in the scope of the studyvariety-based yield estimation models were developed, and yield estimates were made for the relevant years.
