| description | Water scarcity is a major challenge to wheat productivity under changing climate conditions, especially in arid and semi-arid regions. During recent years, different agronomic, physiological and molecular approaches have been used to overcome the problems related to drought stress. Breeding approaches, including conventional and modern breeding, are among the most efficient options to overcome drought stress through the development of new varieties adapted to drought. Growing drought-tolerant wheat genotypes may be a sustainable option to boost wheat productivity under drought stress conditions. Therefore, the present study was conducted with the aim to screen different wheat genotypes based on stress tolerance levels. For this purpose, eleven commonly cultivated wheat genotypes (V<sub>1</sub> = Akbar-2019, V<sub>2</sub> = Ghazi-2019, V<sub>3</sub> = Ujala-2016, V<sub>4</sub> = Zincol-2016, V<sub>5</sub> = Anaj-2017, V<sub>6</sub> = Galaxy-2013, V<sub>7</sub> = Pakistan-2013, V<sub>8</sub> = Seher-2006, V<sub>9</sub> = Lasani-2008, V<sub>10</sub> = Faisalabad-2008 and V<sub>11</sub> = Millat-2011) were grown in pots filled with soil under well-watered (WW, 70% of field capacity) and water stress (WS, 35% of field capacity) conditions. Treatments were arranged under a completely randomized design (CRD) with three replicates. Data on yield and yield-related traits (tillers/plant, spikelets/spike, grains/spike, 100 grain weight, seed and biological yield) and physio-biochemical (chlorophyll contents, relative water content, membrane stability index, leaf nitrogen, phosphorus, and potassium content) attributes were recorded in this experiment. Our results showed that drought stress significantly affected the morpho-physiological, and biochemical attributes in all tested wheat varieties. Among the genotypes, all traits were found to be significantly (<i>p</i> < 0.05) higher in wheat genotype Faisalabad-2008, including biological yield (9.50 g plant<sup>−1</sup>) and seed yield (3.39 g plant<sup>−1</sup>), which was also proven to be more drought tolerant than the other tested genotypes. The higher biological and grain yield of genotype Faisalabad-2008 was mainly attributed to greater numbers of tillers/plant and spikelets/spike compared to the other tested genotypes. The wheat genotype Galaxy-2013 had significantly lower biological (7.43 g plant<sup>−1</sup>) and seed yield (2.11 g plant<sup>−1</sup>) than all other tested genotypes, and was classified as a drought-sensitive genotype. For the genotypes, under drought stress, biological and grain yield decreased in the order V<sub>10</sub> > V<sub>2</sub> > V<sub>1</sub> > V<sub>4</sub> > V<sub>7</sub> > V<sub>11</sub> > V<sub>9</sub> > V<sub>8</sub> > V<sub>3</sub> > V<sub>6</sub>. These results suggest that screening for drought-tolerant genotypes may be a more viable option to minimize drought-induced effects on wheat in drought-prone regions. |
