Physiological assessment of drought tolerance in wheat (Triticum aestivum L.) varieties under moisture stress conditions
Drought is one of the major limiting factors in wheat production in Pakistan. Five commercial wheat varieties; Chakwal-97, Inqilab-91, Margalla-99, NR-234 and Wafaq2001 were grown in pots in glasshouse. Plants were subjected to three consecutive drought cycles at tillering, pre-anthesis and milky growth stages by withholding water till leaf rolling started. Measurements of physiological respons...
متن کاملGenetic analysis of agronomic and physiological traits of bread wheat (Triticum aestivum L.) using generation mean analysis under drought stress conditions and spring planting in the cold climate
Study of heritability and gene action to improve agronomic and physiological traits, especially under drought stress conditions, are very important. The objectives of this study were to investigate heritability for important agronomic traits and some physiological characters in a cross between two spring wheat cultivars. The experiment was carried out using different generations (BC1, BC2, F3, ...
متن کاملGenetic Analysis and QTLs Identification of Some Agronomic Traits in Bread Wheat (Triticum aestivum L.) under Drought Stress
In order to study the genetic conditions of some agronomic traits in wheat, a cross was made between Gaspard and Kharchia varieties. F2, F3 and F4 progenies with parents were evaluated under drought conditions. Three-parameter model [m d h] considered as the best fit for number of fertile tiller and flag leaf length using generations mean analysis method. For number of grain per spike and main ...
متن کاملEstimation of Genetic Control Model for Agronomic Traits in the Progeny of Marvdasht and MV-17 Wheat Cross under Normal and Terminal Drought Stress Conditions
The study of the genetic structure controlling agronomic traits is one of the preconditions for selecting the appropriate breeding method. In order to analyze genetic of some agronomic traits of bread wheat using generation mean analysis, parents and different generations resulting from the cross of Marvdasht × MV-17 wheat cultivars were assessed in a randomized complete block design with three...
متن کاملStudy of Expression Pattern of Some Transcription Factors in Wheat under Drought Stress and Zinc Nanoparticles
Under drought stress condition, the signaling system induces expression of certain genes to counteract the deleterious effects of environmental stress. Among the essential micronutrients for plant growth and development, zinc has an important role in many plant metabolic processes including gene expression and stress tolerance. In order to investigate the effect of drought stress and ZnO on r...
