Abstract: The study was conducted at the Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad, Pakistan to evaluate the drought stress tolerance efficiency of wheat cultivars. Eight wheat (Triticum aestivum L.) genotypes namely (Pasban-90, Inqalab-91, Auqab-2000, AS-2002, Sahar-2006, Shafaq-2006, Lasani-2008, and FSD-2008) were used for screening in laboratory. Three techniques were used for the screening. These techniques are (I) seed germination at -0.6 MPa external water potential (PEG-6000), (2) seedling growth after 14 days at -0.6 MPa (PEG-6000), and (3) plant water relations of seven-week-old pot-grown plants. Significantly highest germination stress tolerance index, root length stress tolerance index and the water content was recorded in Lasani-2008 and lowest was recorded in Auqab-2000. Dry matter percentage was recorded significantly highest in pasban-90 while the lowest dry matter percentage was observed in auqab-2000. FSD-2008 gained maximum plant height and was recorded minimum in Inqilab-91. Relative saturation deficit was significantly highest in Auqab-2000 while the significantly lowest relative saturation deficit was recorded in case of Lasani-2008. It was concluded from the results that Lasani-2008 performed better under drought and Auqab-2000 was recorded most drought sensitive variety.
