Yield Stability analysis of advanced spring wheat genotypes under non-stress and drought stress conditions
Wheat (Triticum aestivum L.) is the first most important Cereal crop in the world. Drought, among abiotic stresses, is known as the most complicated, devastating. Although drought impedes wheat yield at all growth stages, its negative impacts are more critical during the flowering and grain-filling phases (terminal drought) and results in substantial yield losses. A prolonged and severe drought will result in a significant decrease in the production of crop and serious issues of food supply and food security. Given the growing population in developing countries and Iran and the economic and political importance of producing this cereal, a special look at its production and breeding should be taken.
In order to study Yield Stability analysis of advanced spring wheat genotypes under non-stress and drought stress conditions (stop irrigation in the stage of the emergence of 50% inflorescence of each experimental unit), 28 genotypes were evaluated in 2016-2017 and 2017-2018 cropping yearin two separate experiments with a randomized complete block design with three replications in the research field of Islamic Azad University of Tabriz.
Combined analysis of variance under two conditions in two crop years revealed a statistically significant difference between studied genotypes for all traits (P
