ABSTRACT
Among several factors known, drought remains the most important factor affecting wheat yield worldwide. Under the present study, total eleven wheat genotypes were screened to study the physiological and biochemical characters for drought tolerance. Pot experiment for two seasons was carried out with a view to understand the traits which help to find out the drought tolerant wheat genotypes quickly. Stress treatment was given on 60, 70 and 80 days after post-sowing and non stress (well watered) as control. Analysis of variance showed significant results for all traits studied. Stress significantly affected the 50% maturity and decreased the plant height, spike length and grain yield. Compared with drought susceptibly index (DSI), drought tolerance efficiency (DTE %) was found to be increased in all genotypes under stress conditions. Genotypes for membrane stability index (MSI %), proline and total soluble sugar content were also analyzed. Results showed that, increased MSI, proline, sucrose and glucose helped all genotypes to stand better under stress than control ones. Physiological characters are the yield stability parameters and could be useful for evaluating drought tolerance wheat genotypes while a biochemical character plays a role in osmotic adjustment including stabilization of cell membrane under stress conditions.
