BREEDING FOR ANTIOXIDANT CONTENT IN GRAIN AS A PROMISING TREND IN OBTAINING HEALTHY FOOD PRODUCTS

According to the Food Security Doctrine of the Russian Federation, there are plans for the nearest future to expand the assortment of healthy food products for the country’s population, so a search for relevant food sources is needed. The substances that may aid to prevent a number of serious human diseases include antioxidants, while one of the important quality parameters in food products and their ingredients is their antioxidant activity. Today, the aggregate content of antioxidants and their antioxidant activity have been identified with sufficient accuracy for vegetables and fruits. At the same time, the whole cereal grain has been found to provide higher quantities of bound polyphenols than the equivalent portion of soft fruits or widely consumed vegetables. These compounds are available for metabolism in the large intestine, and thus can produce a beneficial effect on human health. Additionally, a case study of 30 different breakfast cereals has shown that the levels of polyphenols in an average portion of oat-based cereals (40 g) are matchable with those of vegetables or fruits. It is widely known that oat and barley grains have high nutritional value, contain unsaturated fatty acids, basic minerals, proteins and β-glucans (the highest levels among cereal crops), and are characterized by the presence of diverse chemicals with antioxidant properties. In recent years, research efforts have been started in a number of Western countries to analyze the content of antioxidants in the grain of various cereal crops. In today’s Russia, only a small number of works are dedicated to studying these important chemical compounds in oat and barley grain. It should be mentioned that, although cereal crops are recognized as one of the main components in human diet, the research conducted to determine their antioxidant activity has clearly been insufficient. In order to attract the attention of Russian plant scientists, plant breeders, plant physiologists, geneticists and biotechnologists, a survey of modern publications on this problem is presented

Adaptive potential of oat accessions in the context of their chemical and physical grain characteristics

Providing high and stable grain harvests with high content of valuable compounds in grain is an important task of crop production. The aim of the study was to assess the adaptability of oat accessions through the analysis of their chemical and physical properties and disclose relationships among adaptability indicators based on these characteristics.Eighteen oat accessions from the VIR collection, grown for 3 years in Eastern Siberia, were assessed. The content of β-glucans and oil, 1000 grain weight, and test weight were analyzed. Four adaptability indicators were measured for the aforesaid characters.Plasticity and stability parameters of the accessions showed no significant differences between the naked and hulled oat forms. Cvs. ‘Sapsan’ (k-15444) and ‘Aldan’ (k-15115) demonstrated the best adaptability in the content of β-glucans in grain, ‘Sayan’ (k-14043) and ‘Vyatsky’ (k-14960) in oil content, ‘Korifey’ (k-15113) and ‘Taidon’ (k-15183) in 1000 grain weight, and ‘Korifey’ and ‘Gosha’ (к-15120) in their test weight. Among the naked oat accessions, significant relationships were recorded between the adaptability indicators of the content of β-glucans or oil in grain and those of the test weight as well as between the average 1000 grain weight of the accessions and the parameters of their plasticity (negative correlations) or stability (positive correlations) for the said physical character.There is a high risk of obtaining hulled oats with reduced levels of oil in their grain, when selected for high stability for this character. It is assumed that successful oat breeding for increased adaptability in 1000 grain weight will be accompanied by an increase in grain size. The possibility of indirect estimation of the adaptability of naked oat accessions according to their β-glucan or oil content is shown on the basis of calculating their adaptability according to the test weight of their grain

The study of oat varieties (Avena sativa L.) of various geographical origin for grain quality and productivity

In order  to identify samples  with a minimum  and  maximum  content of β-glucans  in the  grain, screening of oats grown in Eastern Siberia for three  years was performed. To determine the prospects for further use of oat samples, other chemical, physical and production characteristics were measured in parallel: the protein  and oil content in the grain, its film content, test weight, 1000 grains weight, the vegetation period and the yield. The object of a comprehensive evaluation was 14 hulled and naked 5 VIR (N.I. Vavilov All-Russian Institute of Plant Genetic Resources) oats samples of different origin, mainly from Siberia. The hulled samples formed grains with β-glucan content from 2.9 to 5.2 %, while the naked ones, from 3.7 to 4.8 %. The lowest values were in the Krasnoyarsk varieties Tubinskiy, Kazyr, Sayan (about 3 %); the highest, in the foreign accession Local Tunisia 1 (5.2 %). The highest oil content was shown by Tubinsky, Kazyr and Sayan, all currently cultivated in the Krasnoyarsk region. An increased accumulation of protein in grain was observed in the hulled variety Local Tunisia 1 and the naked accession of Vyatskiy. According to the content of β-glucans  in the grain, taking into account its other characteristics and yield values, the best samples for the food direction (the maximum level of these substances) are Local Tunisia 1, Medved and Taidon, and for feed use (the minimum level) are Tubinskiy, Vyatskiy and Golets. There was no noticeable advantage of naked samples  in comparison with hulled ones in the content of β-glucans  in the grain. A high strength of the positive relationship between the content of oil or β-glucans  in the grain and the year of oat cultivation was observed in the hulled samples. In naked forms, a clear link between the concentrations of chemicals in the different  grain samples  of oats and the year of cultivation has not been established

Evaluation of barley genotypes for the content of <i>β</i>-glucans in grain and other valuable features in Eastern Siberia

Background. The aim of the research was to identify barley germplasm accessions with the minimum and maximum content of β-glucans in their grain in combinations with other improved useful traits.Material and methods. The material for analysis were 18 hulled and 8 naked barley accessions of various ecogeographic origin from the collection of the N.I. Vavilov All Russian Institute of Plant Genetic Resources (VIR), which were grown under the conditions of Eastern Siberia in 2016–2018.Results. Hulled accessions yielded grains with β-glucan content from 3.18 to 4.51%; naked ones, from 3.18 to 5.21%. According to the minimum value of the studied qualitative trait (3.18–3.43%), cultivars of Siberian breeding were identified: ‘Mayak’ (k-29622, Krasnoyarsk Territory) and ‘Tarsky 3’ (k-30719, Omsk Province), plus cv. ‘AC Albright’ (k-30599, Canada); according to the maximum value (5.06–5.21%), the naked accessions Nudum 155 (k-13328, Ukraine) and ‘Nudum 95’ (k-31125, Chelyabinsk Province). The highest protein content in grain (16.63–18.36%) was found in the accessions Nudum 155, Nudum 7566 (k-29453, Kyrgyzstan) and ‘Nudum 95’. The accessions Nudum 155 and ‘Nudum 95’ were characterized by combined high contents of β-glucans and protein in their grain. Early maturity and increased productivity were shown by the cultivars ‘Tarsky 3’, ‘Kolchan’ (k-31039, Altai Territory), ‘Zolotnik’ (k-30845, Altai Territory), ‘Abalak’ (Krasnoyarsk Territory, Tyumen Province), and ‘AC Albright’ (Canada). A significant positive relationship was found between the content of β-glucans and the weight of 1000 grains in both forms of barley.Conclusion. According to β-glucan content combined with other valuable characteristics in grain, the accessions ‘Mayak’, ‘Tarsky 3’ and ‘AC Albright’ are of interest for the improvement of fodder cultivars, while ‘Nudum 95’ and Nudum 155 are promising for breeding for food

Evidence of a dibaryon spectrum in coherent π0π0d photoproduction at forward deuteron angles

The coherent reaction, was studied with the BGOOD experiment at ELSA from threshold to a centre-of-mass energy of 2850 MeV. A full kinematic reconstruction was made, with final state deuterons identified in the forward spectrometer and decays in the central BGO Rugby Ball. The strength of the differential cross section exceeds what can be described by models of coherent photoproduction and instead supports the three isoscalar dibaryon candidates reported by the ELPH collaboration at 2.38, 2.47 and 2.63 GeV/c2. A low mass enhancement in the invariant mass is also observed at the ⁎ centre-of-mass energy which is consistent with the ABC effect. At higher centre-of-mass energies, a narrow peak in the invariant mass at 2114 MeV/c2 with a width of 20 MeV/c2 supports a sequential two-dibaryon decay mechanism

Measurement of the γ n → K0 0 differential cross section over the K∗ threshold

The differential cross section for the quasi-free photoproduction reaction gamma(n)-&gt; K-0 Sigma(0) was measured at BGOOD at ELSA from threshold to a centre-of-mass energy of 2400 MeV. Close to threshold the results are consistent with existing data and are in agreement with partial wave analysis solutions over the full measured energy range, with a large coupling to the Delta(1900)1/2(-) evident. This is the first dataset covering the K* threshold region, where there are model predictions of dynamically generated vector meson-baryon resonance contributions
