One of the world's most important crops, barley, was domesticated in Near East around 11,000 years ago. Barley is a highly resilient crop, able to grown varied and marginal environments, such as regions high altitude latitude. Archaeobotanical evidence shows that barley had spread throughout Eurasia by 2,000 BC. To further elucidate routes which cultivation through Eurasia, simple sequence repeat (SSR) analysis used determine genetic diversity population structure three extant taxa: (Hordeum...
Background. Barley ( Hordeum vulgare L.) is the earliest in maturity and most flexible cereal crop, with a wide variety of forms. There are groups covered naked varieties within cultivated barley species. The interest has currently re-emerged due to easy separation floral glumes from kernel during threshing increased content biochemical components. However, breeders Russia still paying much less attention barleys that they do ones. Materials methods . In 2021–2023, 271 accessions VIR...
The lodging of barley significantly limits its potential yield, leads to the deterioration grain quality, and complicates mechanized harvesting. More than 30 dwarfness semi-dwarfness genes loci are known for barley, their involvement in breeding can solve problem lodging. most common dwarfing alleles sdw1/denso (HvGA20ox2), uzu1 (HvBRI1), ari-e (HvDep1). aim this study was design dCAPS markers sdw1.c ari-e.GP molecular screening accessions from VIR collection identifying these other commonly...
Emmer wheat, Triticum dicoccon schrank (syn. T. dicoccum (schrank) schÜbl.), is one of the earliest domesticated crops, harboring a wide range genetic diversity and agronomically valuable traits. The crop, however, currently largely neglected. We provide wealth karyotypic information from comprehensive collection emmer wheat related taxa. In addition to C-banding polymorphisms, we identified 43 variants chromosomal rearrangements in dicoccon; among them 26 (60.4%) were novel. T7A:5B...
Alike to Reduced height-1 (Rht-1) genes in wheat and the semi dwarfing (sd-1) gene rice, sdw1/denso locus involved metabolism of GA, was designated as 'Green Revolution' barley. The recent molecular characterization candidate HvGA20ox2 for allows estimate impact functional polymorphism this on variation agronomically important traits
Climate changes leading to higher summer temperatures can adversely affect cool season crops like spring barley. In the Upper Midwest region of United States, one option for escaping this stress factor is plant winter or facultative type cultivars in autumn and then harvest early before onset high-temperature stress. However, major challenge breeding such incorporating sufficient hardiness survive extremely low that commonly occur production region. To broaden genetic base University...
Background. Barley ( Hordeum vulgare L.) is an important source of nutrients, such as starch, protein, and various dietary fibers. β -Glucans are soluble fibers found in high amounts oat barley grain, so they becoming increasingly interesting due to their numerous functional bioactive properties. The increased interest -glucans a supplement component food calls for convenient, inexpensive affordable method quantitative determination these compounds. Materials methods. An overview given on...
Background . The possibility of applying near-infrared reflectance (NIR) spectroscopy for rapid assessment various biochemical parameters in barley varieties and forms is discussed. data obtained by the Biochemistry Molecular Biology Department VIR served to construct calibration models content protein, starch, oil, beta-glucans, total phenolic compounds (PhC) grain, facilitating further screening samples. Materials methods chemical composition grain was studied naked covered spring (...
This review surveys the current state of taxonomy, origin, and utilization prospects for naked barley. The cultivated barley Hordeum vulgare L. incorporates covered groups. Naked barleys are divided into six-row (convar. сoeleste (L.) A. Trof.) two-row nudum Trof.). groups include botanical varieties differing in structural features spikes, awns, floret spikelet glumes, color kernels. centers morphogenesis scrutinized employing archeological paleoethnobotanical data, diversity its forms....
Background. Diseases and pests cause great damage to barley stands harvests. Harvest losses from harmful organisms reach 25–30%. Materials methods . During 2017–2020, 46 spring cultivars the VIR collection, listed in State Register for Selection Achievements, were studied their resistance fritfly, net spot blotches, brown rust, powdery mildew. The tests carried out field with provocative colonization by fritfly under natural infection pressure of leaf pathogens. Results conclusions. In 2017,...
Under conditions of climate change, the assessment stability genotypes is particular importance. To conduct directed selection with a narrow or broad reaction rate, it necessary to assess their already in early stages breeding. The aim study was breeding significant traits oat and barley samples contrasting ecological geographical conditions. 25 were studied over 3 years under St. Petersburg Tambov Region. Varieties are characterized by average values economically valuable genotype...
Background. The most rational way to reduce barley crop losses from diseases, pests and adverse edaphic factors is cultivation of resistant varieties. specificity the host– pathogen interactions necessitates a constant search for new donors resistance breeding, phytosanitary monitoring cultivars. Materials methods . research material comprised 248 cultivars included in State Register Selection Achievements Admitted Usage Russian Federation – 168 were developed domestically, 80 by foreign...
Cereal crops, such as oats and barley, possess a number of valuable properties that meet the requirements for functional diet components. This review summarized available information about bioactive compounds oat barley grain. The results studying structure physicochemical cell wall polysaccharides are presented. main components flavonoids formation pathway shown data, concerning anthocyanins biosynthesis in various tissues, discussed. Moreover, we analyzed structural regulatory genes...
A set of 185 pairs accessions with the same name from Russian and Nordic collections barley were grown in field Pushkin scored by person using a morphological descriptors. No differences detected majority (63%).In four out six no for any agro-botanical characters. The are most likely duplicates. In 13% pairs, probably distinct another 24% fell in-between these categories required further investigation. Simple screening can reduce number [The work is dedicated to Sergey M. Alexanian, Vice...
In December 2023, the leading mycologist-phytopathologist of Russian Federation, head laboratory plant immunity to diseases All-Russian Research Institute Plant Protection (VIZR), Doctor Biological Sciences, Professor, Academician Academy Sciences Olga Silvestrovna Afanasenko celebrates her anniversary. The main direction O.S. Afanasenko’s work is a comprehensive study mechanisms variability in populations phytopathogenic fungi, race-forming processes and interorganismal genetics...
Few people know about the existence of such a grain crop as spelt and its benefits for human health. This is unique product with balanced vitamin mineral composition, surpassing even soft wheat in content valuable substances. The center origin this Mediterranean countries. first mentions spelled are found Ancient Egypt, Babylon, Greece, Turkey Armenia. After long period oblivion, Triticum dicoccum (Schrank) Schuebl reappeared crops European countries actively cultivated Iran, India, Turkey,...
