Barley, a widely grown cereal grain commonly used to make beer and other alcoholic beverages, possesses a large and highly repetitive genome that is difficult to fully sequence. Now a team led by scie...
Rare Virulences of Barley Powdery Mildew Found in Aerial Populations in the Czech Republic from 2009 to 2014
Blumeria graminis f.sp. hordei Hordeum vulgare specific resistances
2015/4/1
In breeding plants for resistance to disease pathogens major genes are often used. They mostly confer a resistance, which can be overcome by a corresponding pathogen virulence specific to the resistan...
Breeding for enhanced drought resistance in barley and wheat – drought-associated traits, genetic resources and their potential utilization in breeding programmes
drought resistance genetic mapping genetic materials plant water regime QTL analysis
2014/12/1
Drought represents the most devastating abiotic stress factor worldwide. It severely limits plant growth and development as well as agricultural characteristics including the final yield. The aim of t...
Newly discovered genes for resistance to powdery mildew in the subtelomeric region of the short arm of barley chromosome 7H
DNA marker genetic mapping Hordeum vulgare simple sequence repeats
2014/2/24
Two dominant genes for resistance to powdery mildew (caused by Blumeria graminis f.sp. hordei) from the PI296825 and PI466461 accessions of wild barley (Hordeum vulgare subsp. spontaneum) were identif...
Effect of the nud gene on grain yield in barley
advanced backcross lines doubled haploids naked barley nud gene QTL mapping yield
2014/2/25
Naked barleys are less yielding than the hulled ones while the reason for this difference has not been definitely clarified. To investigate the effect of the nud gene on yield, a barley doubled haploi...
Presence of the Newly Designated Powdery Mildew Resistance Landi in some Winter Barley Cultivars
Blumeria graminis f.sp. hordei Hordeum vulgare pathogen isolates reaction types
2014/2/25
In the last two decades, resistance to the powdery mildew pathogen has been investigated in a large number of barleys in the Czech Republic. Several tens of winter barley cultivars were identified wit...
Determining the levels of genetic variation using SSR markers in three Turkish barley materials known as Tokak
Barley genetic variation landrace microsatellite markers
2010/2/24
Genetic variations are the raw materials of plant breeding and have been increasingly narrowed due to various reasons. Landraces are good sources of genetic variation, but need to be characterized fir...
Relationships between Coefficient of Parentage and Genetic Distance Based on DNA Polymorphism in Barley Cultivars
Barley Coefficient of parentage Cultivar Genetic distance
2009/7/9
Genetic relationships between cultivars are estimated either by coefficient of parentage, which is calculated using the database of cultivars lineage, or from genetic distance, which is calculated ba...
Identification of Japanese Two–Rowed Barley Cultivars by DNA Markers
SSR CAPS DNA marker Barley Identification of cultivars RAPD
2009/7/8
The objective of this study was to establish the technology to identify barley cultivars by the DNA markers for the purpose of managing the foundation seeds and for protecting the breeder’s right and ...
Production of Doubled Haploid Lines for Genetic Analysis of Useful Characters of Malting Barley
Genetic analysis Doubled haploid lines Barley Molecular marker H. bulbosum L.
2009/7/8
To develop a DNA marker assisted selection system for lines with recessive resistance gene to all races of barley yellow mosaic virus (BaYMV), we produced doubled haploid lines (DHLs) of barley (Horde...
Relationships between Coefficient of Parentage Estimated from Pedigree Record and Genetic Distance Estimated from DNA Polymorphism in Wheat and Barley Cultivars
Barley Coefficient of parentage DNA marker Genetic distance Kanto region RAPD analysis Wheat
2009/7/8
In breeding, understanding of the genetic background is effective for efficient improvement. The coefficients of parental correlation between the main cultivars of wheat and between those of barley i...
The variation between wild barley lines ( Hordeum murinum, Hordeum bulbosumand Hordeum vulgare spontaneum) orig-inated from Turkey were investigated comparatively at the molecular level with the Rando...
