introduction: more plains of iran are located in arid and semi-arid regions and so agricultural production systems depend heavily on water. recently, the reduction of water resources has become a serious threat for crop production such as cotton planting. therefore, application of low irrigation methods can be an appropriate method to cope with mentioned condition. in addition, it is vital to i...

abstract drought is the most important factor limiting crop yield word wide. osmotic adjustment (oa) and strong and deep root system result in increased cereal drought tolerance through increasing water uptake and water use efficiency. the impact of root structure and physiological traits on drought stress response was studied in three barley cultivars including yousof (drought tolerant), moroc...

The narrow genetic variation of bread wheat is one of the limitations to improve it for drought-tolerance. The research carried out to study the responses of different genotypes and traits to imposed moisture stress. The plant material comprised of 10 Aegilops tauschii accessions as well as a tolerant (BW2) and a susceptible (BW1) bread wheat cultivar. To assess the root and shoot-traits, two s...

The use of high yielding and resistant to drought stress cultivars in crops is one of the proper way to incorporation other water deficit management methods. This study in order to evaluate grain yield and morphological traits, an experiment was conducted with 100 genotypes of durum wheat which were planted based on lattice design with three replications under normal and drought stress conditio...

Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...

Finding the appropriate parents for breeding programs is the main aim of selecting in drought tolerant crops and landraces under stresses conditions. In present survey, eigthey wheat landraces and varieties from different areas of Iran were evaluated in Gorgan agricultural research station (as a normal or potential yield) and Mazrae-Nemoneh (as under stress condition) during two years (1999-200...

In order to determine suitable drought tolerance indices and to identify drought tolerant wheat genotypes, an experiment was conducted at the experimental field of Ardabil Agricultural Research Station in 2010-11 cropping season. Thirty wheat genotypes were evaluated in a randomized complete block design with three replications under stress as well as non-stress conditions. Drought tolerance in...
