Drought Tolerance Studies of Wheat Genotypes

Abstract: To nose out the best drought tolerant wheat variety, an experiment was conducted during 1998-99 at Agronomic Research Farm, Ayub Agricultural Research Institute, Faisalabad, Pakistan. Ten wheat genotypes namely, Inqilab-91, Chakwal-83, Pasban-90, 85205, Rohtas-90, 4072, 4943 and Faisalabad-83 grown under an iron structure with moveable plastic sheet cover for protecting the plants from rain, were exposed to soil moisture stress at milking stage. Stress was imposed simply by withholding one irrigation. Various physiological and agronomic attributes were studied. On the basis of absolute grain yield, cultivar Barani-83 was found to be the most drought tolerant because of its better osmotic adjustment and Inqilab-91 the most sensitive one as it suffered from maximum loss (37.38 %) in grain yield due to decline in 1000- grain weight.
