    As a result of screening of the allelic composition of genes associated with baking properties, a significant genotypic variety of forms of allocytoplasmic spring wheat (ATSGG) from the ATI PFUR collection was established. In addition to the altered forms, 15 genotypes were isolated as a result of recombinations and introgression, in the genome of which the presence of a allel of wild type Wx-B1a (primer 4F / 4R) was detected. Analysis of the content and quality of gluten in these forms of ACPG made it possible to differentiate these genotypes according to their functional characteristics, which are related to baking properties. The amplitude of the differences in the genotypes of the ACPG in terms of the mass fraction of gluten is from 21.7% to 37.8%, the quality of gluten according to the IDK parameters in the majority of the studied genotypes of the I-st group. The genotypes of the category of strong wheat are of particular value: No. 24 (cytoplasm T. timopheevii), in which the mass fraction of gluten is 37.8% (class of super-strong wheat), and also genotypes of the 1st class, in which the gluten content is not less than 32%, and the quality of gluten is not lower than the I-st group (IDK - 43-77 units.). These are genotypes No. 25 (the cytoplasm of T. timopheevii) and No. 29 (the cytoplasm of T.aestivum L., as a result of backcrossing). To the category of strong wheat of the 2nd class (mass fraction of gluten is not lower than 28%, and the quality of gluten is the I-st group), four genotypes are classified. The category of valuable wheat of the 3rd class includes two genotypes, in which the mass fraction of gluten is not less than 25%. However, the quality of gluten in these genotypes is not II-th group, but higher - it corresponds to the I-st group. Genotypes with a specific combination of the mass fraction of gluten characteristic of strong and valuable wheat, with the qualitative characteristics of gluten of the I-th group, expand the range of their intended use in the production of bakery products.Π’ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Π΅ скрининга аллСльного состава Π³Π΅Π½ΠΎΠ², связанных с Ρ…Π»Π΅Π±ΠΎΠΏΠ΅ΠΊΠ°Ρ€Π½Ρ‹ΠΌΠΈ свойствами, установлСно Π·Π½Π°Ρ‡ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ΅ гСнотипичСскоС Ρ€Π°Π·Π½ΠΎΠΎΠ±Ρ€Π°Π·ΠΈΠ΅ Ρ„ΠΎΡ€ΠΌ аллоцитоплазматичСской яровой ΠΏΡˆΠ΅Π½ΠΈΡ†Ρ‹ (ΠΠ¦ΠŸΠ“) ΠΈΠ· ΠΊΠΎΠ»Π»Π΅ΠΊΡ†ΠΈΠΈ АВИ РУДН.

    Dasypyrum villosum is an annual cereal used as a donor of agronomic traits for wheat. Productivity is one of the most important traits that breeding is aimed at. It is a very complex trait, the formation of which is influenced by many different factors, both internal (the genotype of the plant) and external. The genes responsible for the gibberellin sensitivity played a large role in multiplying yields of cereal crops. Another such gene is the Gid1, which encodes a receptor for gibberellins. This article compares the DNA sequences of the Gid1 gene obtained from six Dasypyrum villosum samples. Using a sequence of wheat and rye taken from the GenBank database (NCBI), we selected primers for regions of different genomes (A, B, and D subgenomes of wheat and the R genome of rye), and carried out a polymerase chain reaction on D. villosum accessions of diverse geographical origin. The resulting PCR product was sequenced by an NGS method. Based on the assembled sequences, DNA markers have been created that make it possible to differentiate these genes of the V genome and homologous genes of wheat origin. Using monosomic addition, substitution, and translocation wheat lines, the localization of the Gid1 gene of D. villosum was established on the long arm of the first V chromosome. A phenotypic assessment of common wheat lines carrying substituted, translocated, or added D. villosum chromosomes in their karyotype was performed. Tendency of disappearance of the first chromosome of D. villosum in the lines with added chromosomes was revealed.Dasypyrum villosum (VV) - ΠΎΠ΄Π½ΠΎΠ»Π΅Ρ‚Π½ΠΈΠΉ Π·Π»Π°ΠΊ, Π·Π°Ρ€Π΅ΠΊΠΎΠΌΠ΅Π½Π΄ΠΎΠ²Π°Π²ΡˆΠΈΠΉ сСбя Π² качСствС Π΄ΠΎΠ½ΠΎΡ€Π° хозяйствСнно-Ρ†Π΅Π½Π½Ρ‹Ρ… ΠΏΡ€ΠΈΠ·Π½Π°ΠΊΠΎΠ² для ΠΏΡˆΠ΅Π½ΠΈΡ†Ρ‹.

    A search for the standard model Higgs boson produced in association with a top-quark pair t t Β― H (ttΒ―H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb &#8722;1 and 19.7 fb &#8722;1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H &#8594; hadrons, H &#8594; photons, and H &#8594; leptons. The results are characterized by an observed t t Β― H ttΒ―H signal strength relative to the standard model cross section, &#956; = &#963;/&#963; SM ,under the assumption that the Higgs boson decays as expected in the standard model. The best fit value is &#956; = 2.8 Β± 1.0 for a Higgs boson mass of 125.6 GeV

    Production of prompt J/ &#968; meson pairs in proton-proton collisions at s s&#8730; = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb &#8722;1 . The two J/ &#968; mesons are fully reconstructed via their decays into &#956; + &#956; &#8722; pairs. This observation provides for the first time access to the high-transverse-momentum region of J/ &#968; pair production where model predictions are not yet established. The total and differential cross sections are measured in a phase space defined by the individual J/ &#968; transverse momentum ( p T J/ &#968; ) and rapidity (| y J/ &#968; |): | y J/ &#968; | 6.5 GeV/ c ; 1.2 4.5 GeV/ c . The total cross section, assuming unpolarized prompt J/ &#968; pair production is 1.49 Β± 0.07 (stat) Β±0.13 (syst) nb. Different assumptions about the J/ &#968; polarization imply modifications to the cross section ranging from &#8722;31% to +27%

    Potato is an important staple food crop. Potato tubers require proper treatment before planting and after harvest to produce high yields and avoid storage losses. Among different techniques of potato treatment physical methods are of special interest: thermal treatment using hot water and steam,ultraviolet (including continuous-wave UV using pulsed Xe-lamps) and gamma-irradiation, treatment withmagnetic and electromagnetic fields (including microwaves). The majority of physical methods is envi-ronmentally friendly and can be applied without special registration and in the developing countries. In the present paper, for the first time, the scientific papers on physical methods of potato treatment for the last 35 years are comprehensively reviewed. The review demonstrates that such an approach is perspective both for pre-planting and postharvest treatment of potato. Physical treatment affects biochemical, cellular and physiological status of potato. Methods of physical treatment enable to control phytopathogens,and some methods (ultraviolet and gamma-radiation) even are capable of improving immunity of plants. The main traits of potato tubers that can be influenced by physical treatment are sprouting (stimulation or inhibition), susceptibility to rot and black leg diseases, and starch, reducing sugars and ascorbic acid contents. The tuber response to physical treatment depends on dosage and date of treatment, duration and temperature of storage, agricultural technology and cultivar. Low doses of treatment may be inefficientwhile too high dosage may result in cell deterioration or death and poor immunity, and eventually to disease development. Too early treatment may damage a tuber since it should pass through suberization (wound healing) after harvest; too late treatment requires higher doses. The proper adjustment of treatmentis necessary for cultivar and individual storage conditions.ΠšΠ°Ρ€Ρ‚ΠΎΡ„Π΅Π»ΡŒ являСтся Π²Π°ΠΆΠ½ΠΎΠΉ ΠΏΡ€ΠΎΠ΄ΠΎΠ²ΠΎΠ»ΡŒΡΡ‚Π²Π΅Π½Π½ΠΎΠΉ ΠΊΡƒΠ»ΡŒΡ‚ΡƒΡ€ΠΎΠΉ.

    According to the totality of the quantitative characteristics of the elements of productivity, all 12 Iraqi varieties of soft wheat when reproduced in the non-Black Earth Region of the Russian Federation are classified as productive varieties. However, the results of a comparative study of 12 varieties of soft wheat do not provide a basis for isolating varieties on the basis of the characteristics of the elements of productivity due to insignificant differences in these characteristics, as well as member. A significant variety of Iraqi varieties has been identified in terms of gluten content and quality. 9 varieties of soft wheat from 12 are distinguished by a high content of gluten Ranging from (28,6 to 52,0%). Among them, three varieties combine this property with high quality gluten, (Alrashid, Tamuz-3 and Sabirbeg). There are also three introduced selection varieties with a low gluten content of Ibaa-99 (22,1%), Tahadi (25,5%) and Ibaa-95 (25,6%) which is obviously related to the national specifics of consumer requirements to the grain
