Drought stress is an important limiting factor for plant growth. Using selection indices, it is possible to identify cultivars with high yield in normal and stressed conditions. So, the genetic analysis of drought tolerance indices can play important role in plant breeding programs. In order to identify molecular markers linked with drought tolerance indices in sunflower, 72 recombinant inbre...
Coriander is an annual plant belonging to Apiaceae family that its yield is affected by drought stress. Three experiments (normal irrigation regime, sudden drought stress and gradual drought stress) were conducted according to a randomized complete block design with three replications in 2015 to introduce the most drought tolerant Iranian coriander ecotypes based on several economical traits, a...
Among different environmental stresses, drought is of great importance that induces a highly negative effect on crop production. In order to evaluate drought tolerance in dryland wheat genotypes, 36 genotypes were studied in a randomized complete block design with three replications under rainfed (drought stress) and supplemental irrigation conditions during 2016–2017 growing season in Research...
this study was conducted to determine drought tolerance genotypes with superiority in different stressed environments. to screening quantitative indices of drought tolerance, genotypes of safflower (carthamus tinctorius l.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). significant positive correlation was fou...
in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...
In order to study tolerance of durum wheat (Triticum durum) lines to drought stress and also evaluating stress tolerance indices, an experiment based on randomized complete block design with four replications was conducted under two rain fed and supplementary irrigation conditions at Gachsaran station during 2011-2012 cropping season using 20 durum wheat lines. Results of combined analysis of v...
Drought stress is one of the most important environmental stresses that have limited the production of wheat, especially in arid and semi-arid regions of the world. To recognize drought tolerant rain-fed wheat genotypes and to determine the best tolerance/susceptibility indices, a study was conducted at the Agricultural Research Station of Miandoab for two cropping years (2013-15). The experime...
In order to find drought tolerance cultivars and determine the appropriate Indices to select drought tolerance in sunflower hybrids, an experimental research was conducted as split plot design based on RCB at the research field of college of Abouraihan of university Tehran in Iran-Pakdasht, in 2009. Irrigation rates were considered in the main plots and sunflower hybrids as sub plots. The resul...

To screening quantitative indices of drought tolerance, genotypes of safflower (Carthamus tinctorius L.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). Significant positive correlatio...
