Genotype by environment interaction is a phenomenon that a better genotype in one environment may perform poorly in another environment. When the genotype refers to a quantitative trait locus (QTL), this phenomenon is called QTL by environment interaction, denoted by Q×E. Using a recently developed new Bayesian method and genome-wide marker information, we estimated and tested QTL main effects ...

Genome-wide association studies (GWAS) for amylose, amylopectin and β-glucan concentration in a collection of 254 European spring barley varieties allowed to identify 20, 17, and 21 single nucleotide polymorphic (SNP) markers, respectively, associated with these important grain quality traits. Negative correlations between the content of amylose and β-glucan (R = -0.62, P < 0.01) and amylopecti...

With the aim of understanding and identifying the traits which can be used as the suitable criteria for quick screening of the water deficit tolerant barley genotypes, an experiment based on randomized complete blocks design with three replications was conducted during two years to evaluate the biochemical responses of 20 barley genotypes to full irrigation and terminal water stress in the fie...

despite the importance of forage quality to animal performance, the quality of barley as a feed and forage crop has not been taken into consideration as a selection criterion in its breeding programs. in order to map the genomic regions affecting barley forage quality, two experiments were conducted while employing 72 doubled haploid lines and their two parents (‘steptoe’ and ‘morex’), at the r...

The chamomile species of Anthemis triumfettii (L.) All is one of important medicinal plant belong to Compositae family and it grows as wild species in Zagros and Alborz Mountains, Iran. The aim of this study was to evaluation of morphological and phenological traits and their relationships with essential oil. Seeds of seven accessions were sown in jiffy pots and transferred to field using rando...

Climate change is altering spring snowmelt patterns in alpine and arctic ecosystems, and these changes may alter plant phenology, growth and reproduction. To predict how alpine plants respond to shifts in snowmelt timing, we need to understand trait plasticity, its effects on growth and reproduction, and the degree to which plants experience a home-site advantage. We tested how the common, long...

tion database for the barley accessions is vital to increasing the utility of the collection in choosing parents for Cultivated barley (Hordeum vulgare subsp. vulgare L.) accessions germplasm enhancement, in genetic diversity assessfrom the USDA-ARS National Small Grains Collection (NSGC) have been tested systematically for the past 20 yr for disease and insect ments, and as baseline data for g...

This article represents some current thinking and objectives in the use of molecular markers to abiotic stress tolerance. Barley has been chosen for study as it is an important crop species, as well as a model for genetic and physiological studies. It is an important crop and, because of its well-studied genetics and physiology, is an excellent candidate in which to devise more efficient breedi...

The Pantanal is one of the world's largest tropical wetland areas and harbors high mammal biomass. There is no formal list of dung beetle species, and studies on their functional roles have never being carried out in Pantanal. In this study, we identified dung beetle species occurring in the north Pantanal region (Poconé sub-region, Brazil) and studied their functional organization, by measurin...

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...
