Drought is a serious threat for sustainable agriculture. Barley represents a species well adapted to environmental stresses including drought. To elucidate the adaptive mechanism of barley on transcriptional level we evaluated transcriptomic changes of two contrasting barley cultivars upon drought using the microarray technique on the level of leaves and crowns. Using bioinformatic tools, diffe...
Barley is one of the most important cereals in animal nutrition and it has a role as a substitute source of wheat and rice in diet nutrition. This product is always exposed to damaging factors such as pests and diseases which lead to reduce yield and quality. The Powdery mildew agent, as a biotrophic fungus, seriously causes damage in some barley plantation areas. Similar to other plants, barle...
Genetically well-characterized mapping populations are a key tool for rapid and precise localization of quantitative trait loci (QTL) and subsequent identification of the underlying genes. In this study, a set of 73 introgression lines (S42ILs) originating from a cross between the spring barley cultivar Scarlett (Hordeum vulgare ssp. vulgare) and the wild barley accession ISR42-8 (H. v. ssp. sp...
in other to evaluate grain yield, rate and effective grain filling period of four barley (hordeum vulgaris l.) cultivars in different planting dates, a factorial experiment based on a randomized complete block design was conducted in the islamic azad university of ardabil research station in 2009. the treatments applied were: three levels of different planting dates (september, 23; october, 16 ...
Extended Abstract Introduction and Objective: Barley (Hordeum vulgare L.) is an important crop plant similar to wheat and rice. Barley is a great source of food for human, and it is also used for feeding livestock. The ultimate goal of barley breeding programs is to increase production efficiency and stability on farmers' farms, which is made possible by replacing more productive cultivars wi...
Root plasticity, a trait that can respond to selective pressure, may help plants forage for nutrients in heterogeneous soils. Agricultural breeding programs have artificially selected for increased yield under comparatively homogeneous soil conditions, potentially decreasing the capacity for plasticity in crop plants like barley (Hordeum vulgare). However, the effects of domestication on the ev...
Limited information is available on control of broadleaf weeds in barley and response of barley cultivars to herbicides. Field experiments were conducted from 2007 to 2009 to evaluate post-emergence herbicides for control of broadleaf weeds in four barley cultivars. Herbicide treatments included 2,4-D sodium salt at 500 g ai ha 1, carfentrazone-ethyl at three rates (15, 20 and 25 g ai ha 1), an...
The ability to access alleles from unadapted germplasm collections is a long-standing problem for geneticists and breeders. Here we developed, characterized, and demonstrated the utility of a wild barley advanced backcross-nested association mapping (AB-NAM) population. We developed this population by backcrossing 25 wild barley accessions to the six-rowed malting barley cultivar Rasmusson. The...
BACKGROUND: Barley is one of the main important crops in the world, mainly used for animal feed and malt. OBJECTIVES: This study was conducted to evaluate the comparisons of seed yield and its components, phenological and physiological traits of different barley cultivars under Lorestan environmental condition. METHODS: Current rese...
