Thirty genotypes of maize were evaluated in RBD with two replications under two regimes (i) no water stress and (ii) water stress during 2009-10 in Rabi. Eight water stress tolerance indices viz., stress tolerance (TOL), stress susceptibility index (SSI), stress tolerance index (STI), mean production (MP), geometric mean production (GMP), yield index (YI), stress susceptibility percentage index (SSPI) and modified stress tolerance index(MSTI) were calculated based on grain yield per plant (g) under water stress (Ys) and no water stress (Yp). Yield under Ys had significant positive association with STI, MP, GMP, YI and MSTI. Based upon the mean yield and stress tolerance indices, five genotypes GM-2, PM-3, EH-1731, EC-3160 and EH-1820 were found potentially drought tolerant.
