Screening of drought tolerant rice genotypes of Eastern Indo-Gangetic Plains. 12 days old seedlings of 10 Eastern Indo-Gangetic rice genotypes were exposed to 20% PEG-6000 induced drought stress for 24, 48 and 72 h. On the basis of morpho-physiological and biochemical performances enhanced drought tolerant genotypes were selected. a Root/shoot ratio, b Relative water content, c Chlorophyll content, d Proline content. Error bars represent mean standard deviation (n = 3). Different letters above the error bars indicate significantly different values (ANOVA, P ≤ 0.05)
