Drought stress resistance indicators of chickpea varieties grown under deficit irrigation conditions.

The aim of this study was to determine the drought stress resistance of three chickpea cultivars (Inci, Hasanbey and Seçkin) grown under water deficit conditions and to discuss the use of yield, crop water stress index and chlorophyll index values as drought stress tolerance indicators in breeding studies. Three drought stress levels, (full irrigation = no stress - I, deficit irrigation = moderate stress - I, and no irrigation = severe stress - I) were used as irrigation treatments. The highest seed yield (1,984 kg ha) in severe stress conditions was recorded for the Inci cultivar with a low crop water stress index (CWSI) (0.
