inheritance of several yield-based drought resistance indices was studied by a halfdiallel method using seven winter wheat varieties. the parental lines were such chosen as to represent a broad range of drought stress resistance. the experiment was conducted in a split-plot design at the research farm, faculty of agriculture, zanjan university, iran, in 1998. irrigated vs. rainfed regimes w...

In order to identify drought tolerant chickpea genotypes, an experiment was conducted in the west of Iran, during 2007-2009 cropping seasons. Several selection indices were used to illustrate genotypic differences in response to drought stress. The results of combined analysis of variance showed that year, genotype, stress conditions and their interaction effects were highly significant. Correl...

one of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. in order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...

the objective of this study was evaluation of salt tolerance of elite forage sorghum lines in laboratory and field conditions. salinity treatments were 5, 10, 15, 20, 25, 30 decisimens per meter in laboratory and distilled water as control. lines were kfs1, kfs2, kfs3, kfs4, mfs1, mfs2 and lfs56. the lines also cultivated in saline and non saline field conditions during 2004-2005. electrical co...

We previously reported that type 2 diabetes risk, early impaired glucose tolerance and insulin resistance can be predicted by measuring the fasting levels of certain biomarkers. Here we validated these findings in randomly recruited healthy volunteers (n = 101) based on biomarker expression as well as various non-invasive indices. Weight, body mass index, waist circumference and visceral fat di...

OBJECTIVE To evaluate correlations between insulin secretion and resistance in patients with gestational diabetes mellitus (GDM) and gestational impaired glucose tolerance (GIGT). METHODS Three hundred thirty six pregnant women with an oral glucose tolerance test (OGTT) were tested and measured insulin function indices (IFI), insulin resistance indices (HOMA-IR) as well as blood serum triglyc...
