Drought is a worldwide problem and present climatic changes have even made it is worse in many parts of the world. Exposing plants to water stress adversely affect plant growth and productivity. Twenty seven diverse wheat genotypes of bread wheat were evaluated for seedling trait sunder drought conditions. On the basis of mean values considerable variation was observed for all the characters. Comparison of mean performance under drought stress conditions indicated that the root related traits were the most sensitive traits, followed by shoot related traits. Wheat genotypes Chakwal-50 possessed maximum dry root weight, dry shoot weight and fresh shoot weight while had minimum shoot length. The genotype Ass-11 showed maximum fresh root weight while the genotype Pasban-90 had highest value for root length among studied genotypes. The superior genotypes Chakwal-50 followed by Ass-11 and Pasban-90 can be used to develop new promising and improved varieties for water stress conditions. These can be further exploited in further generations for more improves morphological characters conferring resistance to water stress conditions.
