Endosperm texture has a tremendous impact on the end-use quality of wheat (Triticum aestivum L.). Cultivars of barley (Hordeum vulgare L.), a close relative of wheat, also vary measurably in grain hardness. However, in contrast to wheat, little is known about the genetic control of barley grain hardness. Puroindolines are endosperm-specific proteins found in wheat and its relatives. In wheat, p...

The net form of net blotch caused by the necrotrophic fungus Pyrenophora teres f. teres is a major disease of barley, causing high yield losses and reduced malting and feed quality. Exploiting the allelic richness of wild barley proved to be a valuable tool to broaden the genetic base of resistance of modern elite cultivars. In this study, a SNP-based nested association mapping (NAM) study was ...

in order to study of barely and wheat cultivars tolerance to metribuzin, a factorial experiment was conducted as a completely randomized design, with three replications in greenhouse of agricultural research at ferdowsi university of mashhad. treatments included wheat cultivars (backcross roshan, cross arvand, bahar, sepahan, gascosion, sayonez, bam garmsiry, garmsiri, ghods, pishtaz, chamran a...

Extensive application of imidazolinone (IMI) herbicides had a significant impact on barley productivity contributing to a continuous decline in its acreage over the last two decades. A possible solution to this problem is to transfer IMI-resistance from a recently characterized mutation in the 'Bob' barley AHAS (acetohydroxy acid synthase) gene to other food, feed and malting barley cultivars. ...

The arabinogalactan proteins (AGPs) are involved in a range of plant processes, including cell differentiation and expansion. Here, barley root hair mutants and their wild-type parent cultivars were used, as a model system, to reveal the role of AGPs in root hair development. The treatment of roots with different concentrations of βGlcY (a reagent which binds to all classes of AGPs) inhibited o...

Although barley (Hordeum vulgare L.) is regarded as salt tolerant among crop plants, its growth and plant development is severely affected by ionic and osmotic stresses in salt-affected soils. To elucidate the tolerance mechanism, growth and ion uptake of three barley cultivars, differing in salt tolerance, were examined under different levels of NaCl, K/Na and NaHCO3 in the root medium. The cu...

Malting quality is an important trait in breeding barley (Hordeum vulgare L.). It requires elaborate, expensive phenotyping, which involves micro-malting experiments. Although there is abundant historical information available for different cultivars in different years and trials, that historical information is not often used in genetic analyses. This study aimed to exploit historical records t...

Gene banks around the world hold over 370.000 accessions of barley (van Hintum and Menting, 2003). Although a large number of landraces and obsolete cultivars are stored in genebanks the geographic coverage of this conserved material is far from evenly distributed. For example only a handful of landraces from Northern Europe have been conserved (Jones et al, 2008a). Thus studies of geographic d...

viscous fibers such as -glucan, is associated with lowering of blood cholesterol levels and normalizing blood Dietary fiber is an important quality parameter of barley (Hordeum glucose and insulin, making foods containing these fivulgare L.) but is extremely laborious to measure. Near-infrared (NIR) transmission and reflectance spectroscopy were investigated bers an important part of dietary st...
