摘要：Twenty wheat genotypes such as Bhattai, Gal- axy, Borlaug, Benazir, Sindhu, Ujala-2015, Moomal- 2002. Marvi-2000. Khirman, Sasui. NIA-Sun- hari. TD-1. SKD-1. TJ-83. Sehar-2006, Pakistan- 2013. Kiran-95. Imdad-2005. NIA-Amber and NIA- Saarang were selected for the development of water stress tolerant wheat genotypes through conven- tional plant breeding. Varieties were grown in splitplot design with two treatments and four replicationat the experimental field of the department of PlantBreeding and Genetics, Sindh Agriculture University, Tandojam during 2017 for various traits such as grain yield plant-1 (g), relative water content in leaves (%), flag leaf area (cm2), spike fertility (%), chlorophyll content (rg) and cell membrane stability(%). The analysis of variance showed that genotypes. treatment and treatment x genotypes were significantfor all the traits studied. The average mean perfor- mance of twenty wheat genotypes for grain yield plant-1 and physiological traits showed that varieties. TD-1. TJ-83, Benazir, NIA-Saarang and Imdad-05 proved drought tolerant wheat genotypes they can be grown in water deficit conditions with minimum yield loses. Grain yield plant-l was significant posi- tive associated with physiological traits under water deficit condition which suggested that physiological traits were good indicators for the development of stress tolerant breeding materials.
