Common bean is adapted to relatively cool climatic conditions and temperatures of>30 Cduring the day or>20 C at night result in yield reduction. The long-term goal of breeding for heat tolerance is the development of germplasm with improved field level tolerance under variable temperature conditions. Using previously developed stress indices, this studypresents results fromhigh temperature scre...

maize improvement for high temperature tolerance requires the reliable assessment of parental inbred lines and their combinations. fifteen maize inbred lines were evaluated during 2007 and 2008 in shushtar city (khuzestan province). the inbred lines were planted at two dates: 6 july, to coincide heat stress with pollination time; and 27 july, as normal planting to avoid high temperature during ...

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 determine the most effective indices for quantifying drought tolerance and identify genotypes that are tolerant to water stress in bread wheat, 50 bread wheat genotypes were compared in a randomized complete block design with three replications under both the non-stress dry farming with two complementary irrigation and the water stress dry farming conditions in Khorramabad, Iran. An...

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...

Objective: In order to study genetic variation and effect of drought stress on grain yield and some morphological traits in chickpea, an experiment was conducted on 64 genotypes during 2013-2014 cropping season at deputy of Kermanshah Sararood Dry Land Agricultural Research Institute, located on the western part of Iran. Methods: The experimental design was a randomized lattice design with tow ...

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...
