Chickpea (Cicerarietinum L.) is mainly grown in rainfed area and terminal drought stress is one of the major constrain to chickpea production in India. The present study was undertaken to identify the traits of significance that contribute towards terminal drought tolerance in chickpea. The two chickpea genotypes HC-1 (drought sensitive) and RSG 931 (drought tolerant) and F3 progeny lines of cross HC-1 × RSG 931 were grown in drought microplots and data was recorded for rootand physiological traits under terminal drought stress. The results showed wide variation for root and physiological traits in HC- 1, RSG 931 and F3 progeny lines of chickpea. Significant positive correlation was recorded between seed yield and water potential; seed yield and RWC; seed yield and quantum yield of photosystem II,whereas root traits were not positively correlated with seed yield. The results of present study showed that physiological parameters could be reliable tools for screening of terminal drought tolerance in chickpea.
