Abstract. The purpose of the research is the reaction of spring soft wheat varieties to dry phenomena during the growing season in the forest-steppe zone of the Trans-Urals. Methods. The material was 24 varieties of various biotypes for maturation from the nursery of the competitive variety testing of the Kurgan Research Institute of Agricultural Sciences. Results. The negative effect of the drought reduced the yield in the experiments by 11.9 c/ha, the weight of 1000 grains by 5.7 g, and the nature by 19.7 g/l. The influence of grain size on the yield both in favorable years and in years of drought was noted (r = 0.63…0.98). In arid conditions, vitreous is correlated with yield, 1000 grain weight, in kind, to a lesser extent with gluten content, bread volume, and “flour strength”. The lack of moisture during the grain filling period increased the gluten content by 3.4 %, the quality by 15.1 e. p. IDC, the flour strength by 102.7 e. a., the volume of bread by 106 g/l. In favorable years, the weight of 1000 grains and the vitreous content of the grain correlate with gluten (r = 0.44; r = 0.24–0.84). Indicators of productivity and physical properties of grain increase when sowing at the optimal time, with a certain decrease in the gluten content (by 1.2 %), flour strength (by 5.3 e. a.), bread volume (by 73.2 e. p.). In the early sowing period, moisture deficiency reduces the indicators for all varieties Under these conditions, early-maturing varieties form a larger grain both when sowing at an early time (29.0 g) and when sowing at the optimal (31.3 g). In a drought, the role of the variety is especially high. High drought resistance was shown by the Zauralochka variety of the Kurgan Research Institute of Agriculture, which successfully passed the test in the dry years (2012, 2020) in the GSI system and in the environmental test (KASIB). The yield of the drought-resistant variety Zauralochka on average for the HSU was 20.2 c/ha, exceeding the standard Hercules by 2.2 c/ha. Scientific novelty. The features of the influence of dry phenomena on the yield and the main indicators of the quality of varieties are revealed, the correlation between them is determined. According to drought resistance, a variety of spring soft wheat Zauralochka was selected.

Owing to the climate warming and, as a consequence, the deterioration of the phytopathological situation, associated with the emergence of aggressive races of fungal diseases, as well as the cultivation of susceptible varieties on the main wheat sowing area in Western Siberia, it is important to expand the genotypic diversity of wheat varieties and search for new sources of long-term sustainability. The evaluation results of spring soft wheat varieties of KASIB nursery shuttle breeding set up jointly by scientific institutions of Western Siberia, Kazakhstan and the International Center for the Improvement of Corn and Wheat CIMMYT are presented in the conditions of the southern forest-steppe of Western Siberia. The research was carried out in 2011-2016, using field and laboratory methods. The results of the assessment of the susceptibility of KASIB nursery varieties to brown and stem rust have shown that varieties with high resistance prevail among resistant varieties in all phases of plant development, which indicates targeted selection for immunity with genes of race-specific and age resistance. The use of cluster analysis made it possible to reveal significant differences in productivity and resistance to rust diseases of KASIB varieties. We distinguished wheat varieties from KASIB nursery-garden 14, 15 - Lutestsens 141/03-2 and Sigma (Siberian scientific research Institute of Agriculture), from KASIB nursery-garden 16, 17 - Erythrospermum 85-08 (Omsk SAU), Lutestsens 6/04-4 and Lutestsens 186/04- 61 (Siberian scientific research Institute of Agriculture), resistant to brown and stem rust, exceeding in terms of yield standards, which are recommended to be used as a starting material for wheat breeding in Western Siberia.

In 2013-2019 in the conditions of Kirov region 178 varieties of spring soft wheat from the collection of the Federal Research Center of N.I.Vavilov All-Russian Institute of Plant Genetic Resources (VIR) were studied according to loose smut resistance, plasticity and yield stability. Among studied varieties 36 immune and 12 practically immune to loose smut infestation samples have been revealed. They can be used as sources of resistance in selection. The most favourable conditions for infestation of spring soft wheat plants with loose smut develop since the beginning of blossoming till grain filling. The higher the air temperature and the amount of precipitation during this period, the higher is the percentage of wheat plants affected with this disease. As the percentage of the stems affected by loose smut increased, total yield losses grew as well (r = 0.99). Nineteen varieties of spring wheat significantly exceeded the standard variety Bazhenka (Russia) in yield on an infection background. Five mid-susceptible varieties which showed tolerance to the disease have been selected. They are Tulaykovskaya Nadezhda (Russia), Samgau, Dostyk, Karabalykskaya 91 (Kazakhstan) and Visa (Belarus). During the years the following varieties revealed the highest and stable productivity: Stepnaya 50, Dostyk (Kazakhstan), Kazanskaya Yubileynaya, Niva 2, Provincia, Egisar 29, Sudarushka, Tulaykovskaya Nadezhda (Russia), Hoffman (Canada), UL Pettit (USA) and Leguan (Czechoslovakia). The following varieties were designated as the intensive type: Tyumenskaya 26, Elizaveta, Maria 1, Melodiya, Niva 2 (Russia), Kharkovskaya 10 (Ukraine), Samgau (Kazakhstan), Visa (Belarus), and American varieties Ranger and UL Pettit (b i > 1). Varieties Ranger and UL Pettit showed high productivity in favorable cultivation conditions. Varieties Mazhor (Ukraine), Favorit (Russia) and Karabalykskaya 91(Kazakhstan) (bi<1) should be used on an extensive background. By deterioration of cultivation conditions the productivity of these varieties decreased insignificantly. The relationship between productivity and adaptability parameters has been established (bi , Ноm). The highyielding varieties have been characterized as more plastic (r = 0.69) and stress resistant (r = 0.73).

The practice of manufacturers using substances that stimulate the growth and development of plants, increase their resistance to external influences, and as a result increase the yield and quality of grain, has become a common practice in field cultivation technology. A wide variety of their production requires careful study and detailed application in agricultural practice. In the process of studying the variety of spring soft wheat after treatment with the studied organo-mineral mixtures (OMM) of the B-plus line, PRK «White Pearl» increases the vegetative mass and productivity, and improves the technological qualities of grain. The article presents data on the processing of seeds and plants of ОMM on the formation of the yield of varieties of spring soft wheat Astana and Karaganda 30. Studies have shown that the varietal reaction of soft wheat showed different responsiveness to treatment with drugs. Thus, grain yield was obtained from the use of the B-plus line of PRK «White Pearl» - Astana varieties 27.87 c/ ha, Karaganda varieties 30 - 32.16 c / ha (increase + 6.3; 8.75 c / ha in comparison with the control) with an increase in the amount of gluten by 0.1-2.2% and its quality.
