This experiment was conducted in order to evaluate the effect of salinity stress on some traits of two barley genotypes (Hordeum vulgare L.) at greenhouse of Department of Agronomy and Plant Breeding, Shahrekord University, Shahrekord, Iran. A factorial experiment was carried out based on randomized complete block design (RCBD) with three replications. Treatments included two barley genotypes (...
Understanding the genetic background of complex behavioral traits, showing multigenic control and extensive environmental effects, is a challenging task. Among such traits, migration is known to show a large additive genetic component. Yet, the identification of specific genes or gene regions explaining phenotypic variance in migratory behavior has received less attention. Migration ultimately ...
abstract this reasearch was conducted to study the phenotypic diversity of thymus kotschyanus populations. seeds were collected from natural inhabitats (guilan, mazandaran, west azarbaijan, semnan and qazvin) and planted in qom reasearch station in 2007. a number of some such different morphological and phenological traits of the plants as plant,s height, leaf length, leaf width, oil content, i...
association analysis is a useful method for evaluation of significant association between molecular marker and phenotype of trait. this study was performed to evaluate association between traits related with powdery mildew resistance and molecular markers. this investigation was performed using 77 barley genotypes and aflp markers. in phenotypic evaluation, reaction of seedlings to powdery mild...
Barley (Hordeum vulgare ssp. vulgare) was first cultivated 10,500 years ago in the Fertile Crescent and is one of the founder crops of Eurasian agriculture. Phylogeographic analysis of five nuclear loci and morphological assessment of two traits in >250 domesticated barley accessions reveal that landraces found in South and East Asia are genetically distinct from those in Europe and North Afric...
introduction corn has been recently used for producing ethanol fuel in the major corn-producing countries such as the us and brazil. recent diversion of corn for biofuel production along with the increased world's demand for this feedstuff has resulted in unprecedented rise in feed cost for poultry worldwide. alternative grains such as wheat and barley can be successfully replaced for corn in p...
A total of 206 wheat and 200 barley farmers were interviewed in northeastern Syria to understand farmer perceptions and practice relating to modern varieties, seed sources and seed quality. Wheat farmers had better awareness and grew modern varieties (87%), applied fertilizers (99.5%), herbicides (93%), seed treatment (90%) or insecticides (41%). In contrast barley growers had low awareness (36...
In order to estimate narrow-sense heritability and heterosis for phenological traits, plant height, seed yield and oil yield, F2 progenies of half diallel crosses from six varieties including RAS-3/99, RW008911, 19H, RGS003, Option500 and PF7045/91 along with their parents were evaluated in a randomized complete block design with 3 replications. Diallel analysis revealed significant mean squar...
Global climate models predict an increase in the mean surface air temperature, with a disproportionate increase during winter. Since temperature is a major driver of phenological events in temperate woody perennials, warming is likely to induce changes in a range of these events. We investigated the impact of slightly elevated temperatures (+0.76 °C in the air, +1.35 °C in the soil) during the ...
Weed suppression and yield increasing are among the aims of intercropping systems. So, chickpea and barley intercropping was evaluated at the Agricultural Research Station, Faculty of Agriculture, University of Bu-Ali Sina during 2010 growing season. Experiment was conducted as split plot experiment based on randomized complete block design with three replications. Control (C) and non- control...
