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...

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...

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...

Improvements in the production of doubled haploids in durum wheat (Triticum turgidum L.) through isolated microspore culture
The objective of this study was to produce durum wheat doubled haploid (DH) plants through the induction of microspore embryogenesis. The microspore culture technique was improved to maximize production of gre...

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...

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...

Efficient production of androgenic doubled-haploid mutants in barley by the application of sodium azide to anther and microspore cultures
The aim of this study was to establish a protocol for an efficient production of agronomical and/or physiological mutants from model (cvs. Igri and Cobra) and low-androgenic-responding (cv. Volga) cultivars o...

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
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...

Article
Production of large number of doubled haploid plants from barley anthers pretreated with high concentrations of mannitol
Pretreatment with increasing concentrations of mannitol, from 0.3 to 0.7 M, was used to induce stress in cultured anthers of barley (Hordeum vulgare L.). Three cultivars with varying degrees of androgenetic abili...

Article
On the origin of Spanish two-rowed barleys
To investigate the phylogenetic origin of Spanish two-rowed barleys, we studied 44 accessions of old land-races both morphologically and biochemically to ascertain their similarity with 51 entries of old culti...

Article
Integration of statistical and physiological analyses of adaptation of near-isogenic barley lines
Seven near-isogenic barley lines, differing for three independent mutant genes, were grown in 15 environments in Spain. Genotype x environment interaction (G x E) for grain yield was examined with the Additive...

Quantitative phenotypical expression of three mutant genes in barley and the basis for defining an ideotype for Mediterranean environments
Three mutants induced in the two-rowed barley variety Beka and their three binary recombinants have been used in an attempt to define an ideotype suitable for Mediterranean agroclimatic conditions. Physiologic...
