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.

The impact of contrasting conditions of water availability on the size of the upper internodes in wheat varieties was studied under the conditions of the Orenburg steppe zone. It was noted, that less drought-resistant varieties formed a short upper internodes. We conducted a mathematical analysis of the relationship of productivity and length of ear-carrying internodes of spring soft wheat varieties of different ecological groups. It was established, that we can observe a gradual increase of grain productivity with increasing the length of the upper internodes in the studied range. As a result, the following varities were selected for inclusion into the hybridization: Logachevka, Tulaykovskaya steppe, Tulaykovskaya 1, Tulaykovskaya Belozernaya, Prokhorovka and Uchitel. They have the optimal settings for the presented feature. Using the selected varieties as parental forms can enhance the efficiency of wheat breeding programs for resistance to drought in the forest-steppe zone of the Southern Urals.

Over the past century and at the beginning of the current one, Siberian breeders have been intensively breeding spring soft wheat for improving the yield and grain quality. The ecologically and geographically diverse source material has been used at the breeding and educational institutions of the region. Thus, in the severe Siberian conditions, the wheat gene pool has been painstakingly created. It has been very difficult here to solve the problem of improving the grain quality, but, given the determination and the talent of many breeders and geneticists, the gene pool of valuable and strong wheat varieties has been created. As a result, being formerly a consumer of food wheat, Siberia has now become a region producing high-quality grain for domestic use and sale in the foreign market. The gene pool of spring soft wheat, which is so rich in the volume and quality, has not been studied in full, and not used throughout Siberia. In 2013 – 2015, sixteen valuable and strong varieties of Siberia-bred wheat had been studied in the northern zone of the Tyumen region on the experimental field of the Northern Trans-Ural State Agricultural University. It has been found that the average productivity of the early-ripening Novosibirskaya 16, Tulun 15, and Polyushko varieties over the three years amounted to 2.52 – 2.89 t/ha, and was close to the yield (2.35 – 3.10 t/ha) of the middle-early ripening varieties. In the midseason-ripening group, the Alyoshina and Altayskaya 110 and 325 varieties exceeded the Tyumen-bred standard Lutescens 70 by 0.23 – 0.69 t/ha with the yield of the latter being 2.54 t/ha. In terms of the content and quality of gluten, the following varieties stood out: Iren, Novosibirskaya 15, Tulun 15, Polyushko, Omskaya 36, Skala, Boyevchanka, Pamyati Vavenkova, Tyumenskaya 80, Alyoshina, and Altayskaya 325. In terms of baking properties (3.7 – 4.2 points), the following varieties stood out: Iren, Novosibirskaya 15, 29, 31, Polyushko, Skala, Boyevchanka, Pamyati Vavenkova, Tyumenskaya 80, Tulunskaya 12, and Altayskaya 325, which can be used as the source material for further wheat breeding.

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.

Winter soft wheat is one of the most important crops. New varieties of wheat should be characterized by a set of valuable economic characteristics, but the most relevant is the creation of varieties with high yields and grain quality, resistant to a complex of diseases and other negative factors. The aim of the study was to evaluate new promising varieties of winter soft wheat breeding of the NSC "Institute of Agriculture NAAS" for grain yield, winter hardiness, disease resistance and grain quality. Experimental studies were conducted at the NSC "Institute of Agriculture NAAS" in 2016-2020, research fields are located in the Fastiv district of Kyiv region. Different weather conditions over the years of research have contributed to a better and more comprehensive assessment of varieties on a set of valuable economic characteristics. During field experiments, the generally accepted technology of growing winter wheat was used. The area of the competitive variety testing site was 20.0 m2, repeated four times. Field, measuring and weighing, laboratory and mathematical and statistical methods were used during the research. In 2018, new varieties of soft winter wheat Krasunia Poliska, Mokosha, Pyriatynka, Fortetsia Poliska, Efektna and in 2020 the variety Zemlerob were transferred to the Ukrainian Institute of Plant Variety Examination for qualification examination. Varieties created in NSC "Institute of Agriculture NAAS" by the method of hybridization using as parent components varieties and lines of local and foreign breeding. The variety Krasunia Poliska, belongs to the Lutescens type, is characterized by high drought resistance, resistance to lodging, germination on stumps, grain shedding. The Mokosha variety, belongs to the Lutescens type, has high drought resistance, is resistant to lodging, germination on stumps and grain shedding. Variety Pyriatynka, belongs to the Lutescens type, has high drought resistance, resistance to lodging, germination on the stump, shedding. Fortetsia Poliska, belongs to the Alborbrum type, is characterized by high drought resistance, resistance to lodging, germination on the stump and shedding of grain. Variety Efektna, belongs to the Erythrospermum type, is short (plant height 64-80 cm), characterized by high drought resistance, resistance to lodging, germination on the stump, shedding. The variety of winter soft wheat Zemlerob, belongs to the Lutescens type, has high drought resistance, resistant to lodging, germination on the stump, shedding of grain. The highest grain yield on average over the years of testing was obtained in the variety Fortetsia Poliska - 7.31 t / ha, varieties Pyriyatynka and Zemlerob with indicators of 7.10 and 7.06 t / ha, respectively, were distinguished by high yields. The yields of Mokosha, Effektna and Krasunia Poliska ranged from 6.27 to 6.95 t / ha. According to the increased winter hardiness, the best varieties are Pyriatynka, Krasunia Poliska, Mokosha and Efektna with a score of 8.0-8.2 points. In the varieties Fortetsia Poliska and Zemlerob the score for winter hardiness was 7.8-7.9 points. Estimation of powdery mildew showed that the maximum percentage of lesions on average over the years of research was found in the variety Mokosha (25.5%). As the most stable selected varieties Efektna, Lisova pisnia, Pyriatynka and Fortetsia Poliska (1.7-11.6%). In terms of resistance to brown rust, all varieties showed high resistance, the damage did not exceed 8.0%. The most stable variety was Efektna (0.3%). The greatest damage to winter wheat varieties was found in leaf septoria, which ranged from 19.0 to 39.3%. The greatest resistance to this disease is determined in the cultivar Zemlerob. New wheat varieties should also be characterized by high levels of protein, gluten and other valuable traits that ensure grain quality. The highest protein content was determined in the grains of the varieties Efektna (11.67%), Mokosha (11.62%) and Krasuni Poliska (11.54%). According to the increased content of gluten, the varieties Krasunia Poliska, Lisova pisnia, Mokosha (19.22-19.66%) were distinguished. According to the highest indicators of sedimentation, the varieties Krasunia Poliska, Pyriatynka and Mokosha (34.50-34.84 %) should be noted, these varieties are also the best in terms of a comprehensive assessment of grain quality. New varieties of soft winter wheat Krasunia Poliska, Mokosha, Pyryatynka, Fortetsia Poliska, Efektna and Zemlerob breedibg of NSC "Institute of Agriculture NAAS" are characterized by high grain yield (up to 7.31 t / ha), increased winter hardiness and disease resistance, as well as good indicators of grain quality: protein content - up to 11.67%; gluten - up to 19.66%. The introduction of these varieties into production will allow to obtain high yields of quality grain.

In Western Siberia, the resistance to septoria was tested for samples of wheatgrass of elongated Agropyron elongatum and introgressive lines of spring soft wheat with its genes, created at Omsk State Agrarian University. The experiments were conducted in the field in the forest-steppe zone of the south of Western Siberia (Omsk) in 2013-2016 on an annual natural infectious background. In 2013, the manifestations of septoriosis were weak, in 2014-2015 - moderate, and in 2016 epiphytoty was spread, which led to a severe defeat of varieties of West Siberian selection. A. elongatum samples showed immunity to the disease. In 2013, 15 promising wheat lines were identified that showed high or medium resistance to the Septoria tritici fungus, causing leaf spotting, and Parastagonospora nodorum, which affects leaves and spikes. The lines were predominantly in the middle or middle groups. According to the results of four-year experiments in contrasting weather conditions, the best lines on average showed higher productivity than, or comparable to, the standard varieties, mainly due to the increased number of productive stems of the plant and a high mass of 1000 grains. During the period of observation, there was an increase in the damage of wheat varieties and lines by the causative agents of Septoria, especially S. tritici. In 2013, 8 lines showed high resistance to leaf damage, 10 lines - ears. During the epiphytosis of 2016 year the resistance to S. tritici retained only 2 lines. The resistance to damage to the ear was more stable, in 2016, 6 lines were high, and 5 - medium resistant to P. nodorum. Two lines showed high resistance to septoriosis of leaves and ear. Dedicated lines are recommended for use in breeding soft wheat for resistance to disease.
