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...

To study drought stress on seedling dry weight, proline contents and evaluate of antioxidant enzymes activity in canola genotypes (Brassica napus l.), an experiment were evaluated at laboratory physiology, Shahed University. This experiment was carried out in factorial with CRD design with 4 replications in 2008. The first factor was including levels of dough stress, one without stress as check...

Drought is one of the major abiotic stresses affecting wheat yield. A recurrent selection program was conducted to improve the drought tolerance and yield of bread wheat using drought tolerant advanced breeding lines from a drought tolerant x susceptible cross (HI 1500 x HUW 510). The parental lines were evaluated for yield, biomass and harvest index (HI) in addition to the drought adaptive tra...

The immediate need for the increase in wheat production to meet future world demand, associated with occurrence of drastic climatic events, such as drought, makes it necessary develop drought-resilient genotypes. aims this work were evaluate use drought-tolerance indices selection genotypes, compare genetic gains grain yield using different strategies by means a multi-trait index, and select su...

in order to locate the qtls involved in the inheritance of agronomical, physiological and metabolitical indicators of drought tolerance in barley, an experiment was carried out using a wheat-barley disomic addition lines. this research was conducted in 2003-2004 at the dry land agricultural research institute, sararood, kermanshah, iran. the results of analysis of variance revealed highly signi...

Cold shock proteins (CSPs) enhance acclimatization of bacteria to adverse environmental circumstances. The Escherichia coli CSP genes CspA and CspB were modified to plant-preferred codon sequences and named as SeCspA and SeCspB. Overexpression of exogenous SeCspA and SeCspB in transgenic Arabidopsis lines increased germination rates, survival rates, and increased primary root length compared to...
