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...

A parametric study approach evaluating drained/undrained behavior of sand has been developed as a simple/quick hypo-elastic model capable of being used in engineering applications. The volumetric interaction of sand grains behavior against pore water pressure induces the tendency of soil mass volume change to contract/dilate due to variation of effective mean stress on solid grain, pore water p...

We have investigated the results of alterations in indices pro-oxidant (conjugated diene and malondialdehyde) antioxidant (superoxide dismutase, ceruloplasmin, catalase) systems guinea pigs’ lungs under conditions immobilization stress. The experiment was conducted on 40 female pigs weighing 0.18-0.20 kg. animals were divided into 4 groups, each contained 10 pigs: I – intact (control), II–guine...

drought stress is one of the most important environmental stresses that affect yield of bread wheat strongly. considering that the yield achieved with the interaction of a large number of plant traits and environment, so the morphological and agronomical traits, can serve as selection criteria under environmental conditions. by genetic analysis and estimation of inheritance and mode of gene act...

abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...
