Morphological traits (plant height, peduncle length, length of fourth internode, specific mass of fourth internode, flag leaf length, width and area), physiological traits (gas exchange parameters and relative water content of flag leaf) of 21 bread wheat genotypes grown under irrigated, rain-fed and drought stress conditions were studied during 2012–2013 and 2013–2014 growing years. The 2013–2014 growing year was characterized by less rainfall and higher temperatures compared to the 2012–2013 growing year, which was reflected in the morphological and physiological parameters. Water stress was found to decrease plant height, internode length, as well as productivity. Genotypic differences of studied traits were significant. The studied parameters were influenced by growth condition as well as by growth year. An influence of growth year was more significant than the influence of the growing condition. Reduction in morphological and physiological parameters was significant under drought stress condition. Drought-susceptible and drought-tolerant genotypes were revealed. Water deficit significantly affected grain yield rather than plant height components. In unfavorable 2013–2014 growing season, significant reduction in grain yield was detected in genotypes Aran, Vostorg, Tale 38, Gyrmyzygul 1, Ferrigineum 2/19 and 12th IWWYT No. 8. Less reduction in grain yield was detected in genotypes Sheki 1, Murov 2, Gobustan, Fatime and 7th WON-SA No. 465.

21个面包小麦基因型的形态性状（株高、花序梗长度、第四节间长度、第四节间比质量、旗叶长度、宽度和面积）、生理性状（气体交换参数和旗叶相对含水量）研究了 2012-2013 年和 2013-2014 年的灌溉、雨养和干旱胁迫条件。与 2012-2013 生长年相比，2013-2014 生长年的特点是降雨量较少，温度较高，这反映在形态和生理参数上。发现水分胁迫会降低植物高度、节间长度以及生产​​力。研究性状的基因型差异显着。研究的参数受生长条件和生长年份的影响。生长年份的影响比生长条件的影响更显着。在干旱胁迫条件下，形态和生理参数显着降低。揭示了干旱易感和耐旱基因型。水分亏缺显着影响谷物产量而不是株高成分。在不利的 2013-2014 生长季节，在基因型 Aran、Vostorg、Tale 38、Gyrmyzygul 1、Ferrigineum 2/19 和 12th IWWYT No. 8 中检测到粮食产量显着下降。在基因型 Sheki 1、 Murov 2、Gobustan、Fatime 和 7th WON-SA No. 465。揭示了干旱易感和耐旱基因型。水分亏缺显着影响谷物产量而不是株高成分。在不利的 2013-2014 生长季节，在基因型 Aran、Vostorg、Tale 38、Gyrmyzygul 1、Ferrigineum 2/19 和 12th IWWYT No. 8 中检测到粮食产量显着下降。在基因型 Sheki 1、 Murov 2、Gobustan、Fatime 和 7th WON-SA No. 465。揭示了干旱易感和耐旱基因型。水分亏缺显着影响谷物产量而不是株高成分。在不利的 2013-2014 生长季节，在基因型 Aran、Vostorg、Tale 38、Gyrmyzygul 1、Ferrigineum 2/19 和 12th IWWYT No. 8 中检测到粮食产量显着下降。在基因型 Sheki 1、 Murov 2、Gobustan、Fatime 和 7th WON-SA No. 465。
