A new variety of spring soft wheat aist-45 as a result of a wide environmental test

The assessment of a new variety of spring soft wheat Aist 45 was given based on the analysis data of yield, plasticity, grain quality, and disease resistance. The studies were carried out at the Kurgan Scientific Research Institute of Agriculture, a branch of the Ural Federal Research Center of the Ural Branch of the Russian Academy of Sciences. A test in breeding nurseries (2011-2020) showed an excess of yield over mid-season and mid-late standards (4.4 and 2.8 cwt/ha). In the ecological test under the KASIB (Kazakstan-Siberian network for improving spring wheat) program of 52 varieties in 16 points of Russia and Kazakhstan (2017-2018), Aist 45 variety had a high rating in terms of yield; according to the results of technological analysis, it showed good potential in the content of protein (15.7-16, 3%) and gluten in grain (31.6-32.4%), attributed to valuable wheat. When evaluated for resistance to brown rust against an artificial background in the seedling phase, Aist 45 was assigned to the resistant type (VIZR and VNIIF). Against the infectious background of the RIBSP of South Kazakhstan, the variety showed resistance to septoriosis and pyrenophorosis. Susceptible to dust brand. The variety is capable of forming a stable yield in drought stress conditions and epiphytotic development of brown and stem rust

Assessment of risks caused by impacts exerted on a human body by nitrates contained in food products

Food products contamination with xenobiotics of various genesis exerts negative influence on population health. According to multiple research performed on various territories in Russia, nitrates are basic contaminants occurring in food products and they make a considerable contribution into higher morbidity with specific nosologic forms, notably pathologies which are primarily caused by factors related to nutrition. The paper focuses on analysis of laboratory research data on nitrates concentrations in food products; the data were collected in Altai region and they are taken from research reports issued by certified test laboratories. The authors also performed their own laboratory research at the Institute for Occupational Hygiene and Industrial Ecology of the RF Public Healthcare Ministry; it allowed to conclude that increased nitrates contents in food products were a vital issue which requires further exami-nation and research performed with high precision laboratory research techniques. We assessed hazard quotients (HQ) for nitrates occurring in vegetables and melons, individual carcinogenic risks (ICR), and population carcinogenic risks (PCR). Our hygienic assessment of nitrates concentrations in food products allowed us to reveal boundaries of risk properties variability. It is necessary to work out recommendations how to reduce exposure of Altai region population to nitrates and to give grounds for priority approaches to administrative decision-making aimed at lowering population risks caused by consumption of nitrates-contaminated food products
