Abstract
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.
