Wheat is an ancient small grain cereal with pretty valuable nutrition. The high throughput nutrition makes it an essential part of human life. Wheat is also a staple grain food. Its demand is rising day to date. The wheat is facing water deficiency to sustain its production. The sustainability in its production has becoming confronted due to biotic and abiotic climatic hazards. The shortfall of water in world is rising due to climatic fluctuations. The present study was proposed to screen out valued genotypes of wheat from the present stocks to prepare drought tolerant material against the water deficit milieu. Five potential lines viz., 9618, 9508, 9797, 9493, 10111 and three approved varieties Bakhar-2002, BARS-2009, Chakwal-86 were identified as drought tolerant parents with diverse genetic background. These genotypes performed excellent for seedlings traits. Drought caused significant reduction e.g. 29.93 % in root length, 18.10 % in shoot length, 12.69 % in root to shoot ratio, 40 % in fresh weight, 36.6 % in dry weight and 13.69 % in relative water content. The traits viz., root length, fresh weight and relative water content showed maximum reduction under drought. So the selection of best performing genotypes on the base of root length, fresh weight and relative water content proved as good selection criterion for screening against drought.
