An urgent task of breeding work is the creation of new high-yielding varieties of spring triticale, adapted to the conditions of the Middle Amur region. The object of research is 160 breeding lines of spring triticale (Ukro x DalGAU 1; Ukro x Primorskaya 108; Ukro x Lana; Ukro x Erythrospermum). As a result of the research, a significant influence of weather factors of the environment on the realization of the potential productivity of breeding lines of triticale in SP-2 was established, the share of the contribution "environment" was 77 %. Under stressful growing conditions, two early ripening varieties of triticale were identified – 128 (Ukro x Primorskaya 108) and 219 (Ukro x Erythrospermum). Numbers 104 (Ukro x Lana), 205 (Ukro x Lana), 206 (Ukro x Lana) were characterized by high resistance to Fusarium spike. The average yield of the selection lines of triticale in SP-2 was 2.8 t/ha, in the standard varieties of triticale Ukro and wheat Khabarovchanka – 2.4 t/ha. For the effective selection of promising genotypes, the differentiation of breeding lines of spring triticale by yield and its structural elements was carried out using the methods of multivariate statistical analysis (cluster analysis). As a result of the research, the studied triticale lines were grouped into 4 clusters according to the criterion of the greatest similarity: cluster I – 33 samples, cluster II and III – 24 nomers, cluster IV – 79 selection lines. Samples of the second cluster (Ukro x DalGAU 1 – 102, 116, 115, 119, 120, 103, 104, 106, 109, 117; Ukro x Lana – 178, 181, 185, 188, 182; Ukro x Primorskaya 108 – 122, 123; Ukro x Erythrospermum – 258, 218, 212, 237, 223, 224, 230) are distinguished by the maximum values ​​of the main economically valuable indicators of productivity in the complex hydrothermal conditions of the Middle Amur region.

The varieties of beans that are the least responsive to growing conditions (primarily in terms of moisture supply) by changing the weight of 1000 grains are selected. Coefficient of plasticity (bi <1): UD0302683, UD0302746, UD0302642, UD0303533, UD0302256. These cultivars slightly reduced the weight of 1000 grains due to the deterioration of the moisture supply, ie they are drought-resistant. It should be noted that the varieties that were characterized by the maximum value of grain productivity in quantitative terms, also showed maximum variability in grain productivity over the years of research. These are primarily varieties: UD0300565, the weight of grain from the plant which was 10.6 g, as well as UD0302642, the weight of grain from the plant was 10.5 g, UD0302746 - 11.4 g. - 20%, and UD0302746 - 17%. Therefore, the production needs varieties of common beans that will provide stable and above average yields under adverse growing conditions, and at optimal high levels. Therefore, varieties of common beans were distinguished, which were characterized by lower absolute values in grain productivity and higher stability of the trait during the study period. Such cultivars included UD0303533, whose grain productivity was 8.53 g, and the regression coefficient (bi = 0.81), coefficient of variation (V = 18%), coefficient of agronomic stability (As = 82%); UD0301899 - 7. 88 g, regression coefficient (bi = 0.65), coefficient of variation (V = 15%), coefficient of agronomic stability (As = 85%). That is, these varieties did not respond much to the deterioration or improvement of growing conditions while maintaining stable grain productivity. Given that the coefficient (As) exceeds 70%, the selected varieties of common beans were stable.

Relevance. Each sample is characterized by a number of biological features, due to the recombination of genetic material in the process of its selection. These features are manifested in the reaction of plants to soil-climatic and technological conditions, expressed in the change of the elements of the yield structure and indicators of the level of adaptability of plants to growing conditions, as well as resistance to lodging. New samples have little-known properties that need to be studied and compared in specific soil and climatic conditions, to assess them in order to decide on the possibility of their zoning or culling. The main indicators characterizing the level of agricultural production are productivity, resistance to lodging, since the shortage of grain as a result of lodging of cereals can reach 15-40%. The introduction of new high-yielding varieties on the basis of their testing and the use of the most effective technological methods of cultivation on crops will allow to receive a significant gross harvest.Materials and methods.

Spring barley breeding in the Rostov region is aimed at developing early maturing, drought-resistant, high-yielding varieties with good technological qualities of grain. Productivity is mainly affected by the economic and biological parameters of the variety and the environmental conditions in the growing area. The purpose of the research is to conduct a comparative assessment of spring barley varieties by indicative parameters of ecological plasticity and yield stability to changes in environmental conditions. In 2018-2020, for a targeted study of this impact, trials with 18 spring barley varieties of Russian and foreign breeding to estimate their ecological adaptability and stability were carried out. Square of the plot – 10 m2; experiment was replicated thrice. Soil – chernozem ordinary with humus content in the arable layer at the level of 3.0–3.5%, pH = 7.0–7.1. Phosphorus content – 15–20 mg/kg of soil, exchangeable potassium – 300–500 mg/kg. The estimation of the effect on the ecological plasticity and stability of varieties was carried out according to the method of S.A. Eberhart, W.A. Rassel edited by V.A. Zykin (2005). Indicators of homeostaticity and breeding value were calculated according to the V.V. Khangildin and N.A. Litvinenko method (1981). Over the years of research, the productivity formation was mainly influenced by the factors ‘variety’ (66.1%) and ‘year’ (31.7%). The environmental conditions index showed that more favorable growing conditions were in 2020 (Ij = +0.23); in 2018, on the contrary, they were relatively unfavorable (Ij = –0.19). As a result of the three-year analysis, the highest productivity was identified in the varieties ‘Format’ (4,9 t/ha), ‘Fedos’ (4,8 t/ha) and ‘Gris’ (4,8 t/ha). In general, according to the complex of adaptivity parameters, ‘Format’ variety was distinguished. It has high indicators of breeding value (Sc = 4.6), stress resistance (Ymin-Ymax = –0.3), high stable productivity, as well as a high homeostatic index (Hom = 531) and a low coefficient of variation (V = 3.1%).

The main purpose of modern measuring instrument MI is to perform accurate and reliable measurements in order to obtain complete and reliable measurement information. The MI must be of proper quality, which must be reliably assessed. For technical means, traditional quality indicators have been established, some of which are common to MI. The metrological characteristic is unique to a MI and can be considered one of the most important of MI indicators. The quality of MI is characterized by a certain system of quality indicators. Depending on MI group, the system of quality indicators can differ. The target indicators are specific for each type of product. These indicators require additional analysis. The main metrological characteristics should be referred to the target indicators of MI. For some MI categories, additional indicators can be established, and for others, they are excluded. The methodology of evaluation of MI quality indicators and algorithm of its realization are offered. The digital multimeters as category of MI have been selected for practical comparative evaluation of MI quality indicators. The ten indicators for this category of MI have been refined. Comparative expert evaluation of quality indicators of 12 multimeters was carried out with the involvement of a group of 34 metrology experts. The weight of each of the 10 selected MI quality indicators was determined. The results of expert evaluation of multimeter are presented.
