QTLs for barley yield adaptation to Mediterranean environments in the ‘Nure’ × ‘Tremois’ biparental population
Multi-environment trials represent a highly valuable tool for the identification of the genetic bases of crop yield potential and stress adaptation. A Diversity Array Technology®-based barley map has been develop...

Building bridges: an integrated strategy for sustainable food production throughout the value chain
The food production and processing value chain is under pressure from all sides—increasing demand driven by a growing and more affluent population; dwindling resources caused by urbanization, land erosion, pol...

Open AccessGenetic characterization of a reciprocal translocation present in a widely grown barley variety
Artificially induced translocation stocks have been used to physically map the barley genome; however, natural translocations are extremely uncommon in cultivated genotypes. Albacete is a barley variety widely...

Open AccessAgronomic effects of a reciprocal translocation in a widely grown Spanish barley variety
A large spontaneous reciprocal translocation is present in a widely grown Spanish barley cv. ‘Albacete’. It has been hypothesized that high popularity of ‘Albacete’ with farmers, particularly in semi-arid area...

Open AccessMixed model association scans of multi-environmental trial data reveal major loci controlling yield and yield related traits in Hordeum vulgare in Mediterranean environments
An association panel consisting of 185 accessions representative of the barley germplasm cultivated in the Mediterranean basin was used to localise quantitative trait loci (QTL) controlling grain yield and yie...

Comparative map** of the Oregon Wolfe Barley using doubled haploid lines derived from female and male gametes
The Oregon Wolfe Barley map** population is a resource for genetics research and instruction. Prior reports are based on a population of doubled haploid (DH) lines developed by the Hordeum bulbosum (H.b.) metho...

Article
Open AccessLinkage map construction involving a reciprocal translocation
This paper is concerned with a novel statistical–genetic approach for the construction of linkage maps in populations obtained from reciprocal translocation heterozygotes of barley (Hordeum vulgare L.). Using sta...

Article
Development of wild barley-derived DArT markers and their integration into a barley consensus map
Wild barley-specific genomic libraries were developed for the purpose of creating a ‘comprehensive’ genomic representation of the primary Hordeum genepool capable of more robust genoty** of barley. In order to ...

Genetic relationships between preharvest sprouting and dormancy in barley
Preharvest sprouting (PHS) and dormancy (DOR) can be problems in barley production and end use quality, especially for barley used for seed and malting. Three crosses previously analyzed for DOR inheritance, w...

Article
Patterns of genetic diversity and linkage disequilibrium in a highly structured Hordeum vulgare association-map** population for the Mediterranean basin
Population structure and genome-wide linkage disequilibrium (LD) were investigated in 192 Hordeum vulgare accessions providing a comprehensive coverage of past and present barley breeding in the Mediterranean bas...

Changes in allele frequencies in landraces, old and modern barley cultivars of marker loci close to QTL for grain yield under high and low input conditions
Changes in alleles frequencies of marker loci linked to yield quantitative trait loci (QTL) were studied in 188 barley entries (landraces, old and modern cultivars) grown in six trials representing low and hig...

Map** adaptation of barley to droughted environments
Identifying barley genomic regions influencing the response of yield and its components to water deficits will aid in our understanding of the genetics of drought tolerance and the development of more drought ...

Article
Use of new EST markers to elucidate the genetic differences in grain protein content between European and North American two-rowed malting barleys
A population comprising 102 doubled haploid lines were produced from a cross between Beka, a barley cultivar widely grown in Spain, and Logan, a north American cultivar with inherently low protein content, a c...

Article
Mixed models including environmental covariables for studying QTL by environment interaction
The study of the phenotypic responses of a set of genotypes in their dependence on the environment has always been an important area of research in plant breeding. Non-parallelism of those responses is called ...

Genetic control of dormancy in a Triumph/Morex cross in barley
Seed dormancy in barley (Hordeum vulgare L.) is one of the most important parameters affecting malting. Seed dormancy is quantitatively inherited and variously influenced by the environment. The objectives of the...

Further evidence supporting Morocco as a centre of origin of barley
Thirty-five populations of H. spontaneum from nine countries, encompassing almost all the known range of distribution of the species, Afghanistan, Crete (Greece), Cyprus, Iran, Iraq, Israel, Libya, Morocco and T...

Article
A mutant induced in the malting barley cv Triumph with reduced dormancy and ABA response
Induced mutants in the barley cultivar Triumph have been screened for reduced dormancy. One line, which germinated readily 2 weeks after harvest, was classified as ABA-insensitive, since it could tolerate a t...

Article
The Spanish barley core collection
Spanish barleys constitute a germplasm group of particular interest for breeding purposes, as Spain has been proposed as a possible centre of origin of the crop. The Spanish National Germplasm Bank (Banco Naci...

Molecular marker-assisted selection for malting quality traits in barley
Selection for malting quality in breeding programs by micromalting and micromashing is time-consuming, and resource-intensive. More efficient and feasible approaches for identifying genotypes with good malting...

Verification of barley seed dormancy loci via linked molecular markers
Seed dormancy is a relatively complex trait in barley (Hordeum vulgare L.). Several dormancy loci were identified previously by quantitative trait locus analysis. Three reciprocal crosses were made in the present...
