<p>In this article, we proposed a rationale for choosing the seeding aggregates to improve the quality of ordinary spring wheat sowing in the moderate arid steppe of the Altai Territory. We determined the actual values and variability of spring wheat sowing quality indicators when different sowing units were used. A comparative evaluation of sowing aggregates was made on the basis of a generalized parameter that characterizes the quality of sowing taking into account their equalization. The study compared the following technologies and seeding machines: direct seeding with the use of the EPPK-2.5 complex; zero technology (No-Till) with sowing complex Condor; traditional technology of cultivation of crops with autumn processing with PG-3-5 gun, presowing processing of APK-7.2 and sowing of SZP-3.6A. The compared variants were randomly located, the sowing was carried out in the third decade of May, the rate of sowing was 5 million virgin grains per hectare, spring soft wheat "Altai 70". Determination of quality parameters of sowing (depth of seeding, the number of plants, plant height and their statistics) were conducted in the 2nd decade of June. During 2013-2016, SZP-3.6A crops had the advantage from the number of shoot and it was 346.1 pcs / m2, which is by 1.84 and 2.34 times was higher than Condor and EPPK-2.5 respectively. The height of plants also had an advantage of SZP-3,6A – 282.6 mm, which was higher by 25.4 mm and 71.2 mm than in Condor and EPPK-2.5 respectively. Each indicator of the quality of sowing was characterized by fluctuated magnitude. High coefficient of variation indicated low quality of sowing. We calculated the equalization coefficient for each parameter to assess the uniformity of crops performed by each machine. The SZP-3,6A seeder exceeded the compared seeding complexes for all three parameters, which indicated higher seed uniformity than Condor and EPPK-2.5. Comparative evaluation of the seeding machines Condor and EPPK-2.5 was ambiguous. At the seeding unit EPPK-2.5, the leveling factor was 12.3% higher than in Condor, the seeding rate was 17.8% lower in comparison with Condor, and the plant height was insignificantly (by 2.1%) lower than Condor.</p><p>We suggested a generalized leveling factor to evaluate the sowing aggregates in terms of the quality of sowing, i.e. radius vector drawn up to point A, characterized by the coordinates A (depth of embankment, number of sprouts, and plant height). A better seeding was obtained with the SZP-3.6 A seeding unit (84.2%). The lowest quality parameters for sowing were obtained from the seeding complex EPPK-2.5 (75.9%). Crops with this complex were characterized by the greatest uneven quality of sowing, which requires a correct justification for both the sowing rate, the method of sowing and the width of the rows of cultivated crops according to the technology applied to specific conditions.</p>

The paper presents an analysis of spring soft wheat varieties of different periods of variety change according to ecological plasticity and stability when cultivated in different climatic conditions (2014–2019). To increase the yield of spring soft wheat varieties, much attention is paid to the devlopment of high-intensity forms that respond positively to additional investments in agricultural technology. These varieties must also demonstrate high yield stability as well as plasticity in relation to environmental factors – i.e. the ability to form the high yields in wide range of environmental conditions. In the course of the study, the authors carried out an environmental assessment of ten varieties of four major groups by yield in a five-year field experiment. The yield upper limits, as well as an indicator of stress resistance, were estimated. Based on these data, statistical coefficients of their ecological plasticity and stability, as well as the stability variant, were analyzed. The Agatha and Esther spring wheat varieties showed the most responsiveness to the improvement of cultivation conditions. They can be considered the most plastic varieties. The highest stability index was observed in the Radmir, Amir, MIS, Zlata and Lyubava varieties. The most promising among the new spring soft wheat varieties is the Radmira variety, which has the best adaptive potential, which incidentally allows it to form a stable high level of productivity in changeable climatic conditions. Among the varieties of earlier periods, promising cultivars include the Zlata variety. Its high adaptability is comfirmed by its cultivation in 1,2,3,4 and 7 regions of Russia.

The aim of the research is the assessment of 10 varieties of spring soft wheat approved for use, and 5 promising varieties of spring durum wheat of Russian selection according to yield and adaptability parameters for 2015-2018 on the basis of the results of the test carried out in the southern forest steppe zone of the Tyumen region. Productive and adaptive potential of the varieties was determined by the method of L.A. Zhivotkov co-authored, the average yield in contrast conditions –by the equations of A.A. Rossielle, J. Hemblin, the yield variability – by the method of B.A. Dospekhov, the environmental condition index and ecological plasticity of varieties – by S.A. Eberhart, W.A. Russell, the general adaptive ability of the varieties – by the method of A.V. Kilchevsky, L.V. Hotyleva. The strongest variability of indexes of environmental conditions during the years of testing of the varieties was found in middle-early varieties of spring soft wheat, from -1.08 (2017) to 1.26 (2018). The varieties of spring soft wheat Tyumenskaya Yubileynaya (middle-early, 3.06 t/ha) and Aviada (middle-season, 2.86 t/ha), and of spring durum wheat – Omsky izumrud (3.52 t/ha) were recognized the best in terms of average yield. In the favorable conditions of 2018, on the basis of determination of the percentage of yield of varieties relative to the average among the varieties, the largest productive potential of spring soft wheat varieties was revealed in Tyumenskaya Yubileynaya (middle-early, 111.5 %), Aviada (middle-season, 108.9 %) and spring durum wheat – Omskaya stepnaya (105.7 %). In the unfavorable conditions of 2017, high adaptability was observed in spring soft wheat varieties Ekaterina (middle-early, 118.7%), Ikar (middle-season, 105.0 %) and spring durum wheat – Omskaya stepnaya (105.8 %). Regardless of the specie, all studied varieties had significant yield variability. The most of the varieties were characterized as plastic (bi is equal to or close to 1). Strong responsiveness to change of conditions is determined in spring soft wheat varieties Novosibirskaya 15 (middle-early, bi = 1.11) and Aviada (middle-season, bi = 1.21), and in spring durum wheat Omsky korund (bi = 1.14). The varieties of spring soft wheat Ekaterina (middle-early, Si2 = 1.20), Tyumenskaya 29 (middle-season, Si2 = 0.03) and spring durum wheat Zhemchuzhina Sibiri (Si2 = 0.84) were the best in terms of stability. The varieties of spring soft wheat Tyumenskaya Yubileynaya (midlle-early, GAA = 0.32), Aviada (middle-season, GAA = 0.07) and the spring durum wheat Omsky izumrud (GAA = 0.26) were the best according to the general adaptive ability. The varieties of spring soft wheat Ekaterina (midlle-early) and Aviada (middle-season) and spring durum wheat Omskaya stepnaya were recognized as the best on the basis of the complex assessment of yield and adaptability parameters.

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.
