Cereals including wheat and barley are of primary importance to ensure food security for the 21st century. A combination of lab- and field-based approaches has led to a considerably improved understanding of the importance of organ and particularly of whole-plant (monocarpic) senescence for wheat and barley yield and quality. A delicate balance between senescence timing, grain nutrient content,...
In order to determine the stability and reaction of barley genotypes in different climatic conditions, grain yield of ten barley cultivars were evaluated in five locations. Studied areas were Karaj, Birjand, Kashmar, Sanandaj and Shiraz. The experiment conducted in a randomized complete block designs with three replications in 2013-2014. Genotype by environment interaction effect was significan...
The main purpose of this research was to identify barley promising lines with high grain yield and yield stability for warm region of Iran. In this experiment, 17 barley promising lines and two check cultivars were evaluated in five agricultural research stations; Ahvaz, Darab, Zabol, Gonbad and Moghan, Iran, in 2015-16 and 2016-17 cropping seasons, using randomized complete block design with t...
Soil salinity is an environmental and agricultural problem in many parts of the world. One of the keys to breeding barley for adaptation to salinity lies in a better understanding of the genetic control of stomatal regulation. We have employed a range of physiological (stomata assay, gas exchange, phylogenetic analysis, QTL analysis), and molecular techniques (RT-PCR and qPCR) to investigate st...
The development and growth of plant organs is regulated by phytohormones, which constitute an important area of plant science. The last decade has seen a rapid increase in the unravelling of the pathways by which phytohormones exert their influence. Phytohormones function as signalling molecules that interact through a complex network to control development traits. They integrate metabolic and ...
: In order to study the effect of different nitrogen levels on yield components and seed yield of three barley cultivars, an experiment was conducted in 2011-2012 in a research farm of farming building of Islamic Azad University Khorasgan (Isfahan) Branch located in Khatunabad village (latitude 32o /40' N and Longitude 51o /48' E). A split plot layout within randomized com...
Crop wild relatives adaptively diversified for environmental stresses are valuable resources for crop breeding especially for climate change scenarios, supposedly worsening drought and heat conditions. In this study, genetic variation of 54 barley genotypes comprised of 47 H. vulgare spp. spontaneum genotypes collected from west of Iran along with Reyhan cultivar and six F1 hybrids resulted fro...
The simultaneous sowing of two or more species in the same field without a fixed location relation to each other—mixed intercropping—is associated with problem optimizing agrotechnics for plants different requirements and instability composition crop. An alternative which eliminates these problems can be strip intercropping. Based on published results seven long-term experiments aimed at unders...
Barley traits related to salt tolerance are mapped in a population segregating for a dwarfing gene associated with salt tolerance. Twelve quantitative trait loci (QTLs) were detected for seven seedling traits in doubled haploids from the spring barley cross Derkado x B83-12/21/5 when given saline treatment in hydroponics. The location of QTLs for seedling growth stage (leaf appearance rate), st...
Improving the drought tolerance of barley varieties through the integrated efforts of plant biotechnology and conventional breeding is an important objective in barley breeding. One hundred and fifty eight doubled haploid lines of barley were mapped with 50 SSR and 93 AFLP markers. Agronomic traits such as early growth vigor, plant height, peduncle length, extrude of spike from flag leaf, spike...
