The article describes the structure, architecture, principles of construction and operating modes of the computer software that simulates operators' workplaces of centrifuge uranium enrichment production. We have implemented the networking of computer simulator modules and equipment database. A computer simulator of the isotope separation plant of Siberian Chemical Plant OJSC has been created on the basis of the architecture developed. The main purpose of the simulator is to train the operating personnel for production process control in standard and emergency situations.

The article provides experimental data on the study of breeding material of spring wheat, spelt and lines of interspecific hybrids. On the basis of structural and cluster analyzes, the morphological similarity of the new breeding lines of interspecific hybrids (Triticum durum x Triticum dicoccum) with spring durum wheat varieties and their significant difference from the Runo spelt variety were revealed. Cluster analysis by indicators of structural analysis in 2018-2019 of varieties, breeding lines and interspecific hybrids made it possible to form 7 clusters. Cluster No. 1 deserves attention, in which the high-yielding variety Triada and the hybrid Hordeiform 1461-15, obtained as a result of interspecific hybridization, are grouped (Triticum durum x Triticum dicoccum). The short-stemmed (76 cm) line leukurum 1560-18, allocated in a separate cluster, has a well-grained ear, the most resistant to lodging. Cluster analysis of grain quality made it possible to identify varieties and lines that ensure the collection of protein above the standard varieties of soft wheat Daria, Granny. A new valuable source material with a complex of positive traits for breeding for high productivity was revealed (varieties Triada, Donskaya elegy, hybrid Hordeiform 1461-15). Yield of the Triada variety in 2020 was 5.3 t/ha, of the Donskaya elegy 4.36 t/ha, of interspecific hybrid No. 1461-15 - 4.27 t/ha with LSD05 = 0.4 t/ha, which is significantly higher indicators of other varieties and lines.

Reducing the pesticide load on natural and agroecosystems in the production of agricultural products in crop production is the most pressing problem of the XXI century. Use of disease-resistant varieties of agricultural crops, which makes it possible to completely exclude the use of some of the pesticides required in the technological cycle, is an ecologically and economically significant factor in modern production. Particularly important in the cultivation of disease-resistant varieties is to reduce the probability of the pathogen developing new virulent properties that overcome this resistance of the variety with a long-term existence in production. These conditions are met by multilinear varieties that are heterogeneous in nature. As an object of analysis, we took the Quartet, multilinear in terms of smut resistance, common millet variety, which has been in production since 2001. The variety, with more than 20 years of cultivation in Russia, neighboring countries, as well as Germany and Switzerland, has shown not only excellent yielding qualities, but also actual resistance to local populations of the pathogen. The authors analyzed the difference from the original composition of the component composition of the variety after many years of production, when reseeding with its own seeds, in the conditions of one farm. On the farm, the obligatory method of treating millet seeds against smut was excluded from the cultivation technology.
