Ascochyta blight, caused by Ascochyta rabiei (Pass.) Labrousse (teleomorph=Didymella rabiei), is one of the most serious diseases of chickpea in many countries including Turkey. In this investigation, we searched the reaction of some chickpea varieties against to the causal agent of ascochyta blight disease of A. rabiei in natural conditions and in different locations in the Southeastern Anatolia and revealed some data for the control of this disease. Rainfall and humidity has created ideal conditions for development this disease in the season of production between 2015 and 2016. In these circumstances, determined tolerant varieties and some applications are made in farm conditions against diseases for at least lowering the effect on the yield of chickpea in the winter sowing. As a result, Askan and Arda varieties were identified as the most tolerant varieties against the disease at all locations. It was determined that if these chickpea varieties sown in autumn, seed dressing and foliar spraying is done on time, the negative impact of disease will be minimum on yield.
