The decrease in water resources due to the excessive use of water for irrigation purpose and climatic changes represents a serious world-wide threat to food security. In this regards, 50 wheat accessions were analyzed, using completely random factorial design at the seedlings stage under normal and drought stress conditions. Significant variation was detected among all accessions under both conditions. All characters studied showed variations in the mean values in water deficit environments in studied gemplasm at seedling stage. As seedling fresh weight, dry weight, relative water content, cell membrane thermo-stability, chlorophyll a & b were positively associated among themselves under drought conditions which showed the significance of these attribute for water deficit areas in future wheat breeding programs. Based on their performance, five accessions namely Aas-11, Chakwal-86, Pasban-90, Chakwal-97 and Kohistan-97 were selected as drought tolerant and three accessions namely Mairaj-08, Lasani-2008 and Gomal-2008 were selected as drought susceptible genotypes. The choice of wheat accessions based on the characteristics of the seedlings is informal, low-priced and less hassle. Likewise, the seedlings attributes exhibit moderate to high variation with an additive genetics effects on the environments. Best performance accessions under water deficit environment will be beneficial in future wheat breeding schemes and early screening for the attributes suggested in current experiment will be useful for producing best-yielded and drought-tolerance wheat genotypes to sustainable food security.

由于灌溉用水过多和气候变化导致水资源减少，这对全世界粮食安全构成了严重威胁。在这方面，在正常和干旱胁迫条件下，在苗期使用完全随机因子设计分析了50个小麦种质。在两种条件下，所有种质之间均检测到显着差异。所研究的所有性状均显示出所研究的种质在幼苗期缺水环境中平均值的变化。作为幼苗的鲜重，干重，相对含水量，细胞膜热稳定性，叶绿素a＆b在干旱条件下之间呈正相关，这表明这些属性对未来小麦育种计划中缺水地区的重要性。根据它们的表现，选择了五个种质，即Aas-11，Chakwal-86，Pasban-90，Chakwal-97和Kohistan-97作为耐旱性，选择了三个品种，即Mairaj-08，Lasani-2008和Gomal-2008。干旱易感基因型。根据幼苗的特征选择小麦种质是非正式的，价格低廉的和麻烦的。同样，幼苗的属性表现出中等到高度的变化，并对环境产生附加的遗传学影响。
