Winter Wheat Varieties

In recent years, there has been a significant change in climatic conditions affecting the cultivation and yield of winter wheat. Therefore, the creation of wheat varieties with high adaptive potential is one of the main tasks of modern breeding. A significant component of the overall adaptive potential of winter wheat is winter hardiness, which is determined by a set of characters enabling plants to overwinter. To a large extent, winter hardiness is determined by gene systems that control vernalization requirement duration, photoperiod reaction, and frost resistance. The research is aimed at determining the features of modern winter wheat varieties developed at the V. M. Remeslo Myronivka Institute of Wheat of the National Academy of Agrarian Sciences of Ukraine in terms of winter hardiness components and adaptive potential in the environment of the Central part of the Ukrainian Forest-Steppe. Winter bread wheat varieties Estafeta myronivska, Hratsiia myronivska, MIP Assol, and Balada myronivska were studied. They also were crossed on incomplete diallele scheme with three near-isogenic lines derived from Erythrospermum 604 with different alleles of Vrd genes 1) Vrd1Vrd1vrd2vrd2, 2) vrd1vrd1Vrd2Vrd2, and 3) vrd1vrd1vrd2vrd2. It was established that vernalization requirement duration in the varieties Estafeta myronivska and Balada myronivska was short whereas in the varieties Hratsiia myronivska and MIP Assol it was medium. All the varieties studied have medium photoperiod sensitivity. The results of the hybridological analysis indicate the absence of the Vrd1 and Vrd2 genes in the varieties. Frost tolerance of these varieties is at the same level and higher than in the highly tolerant to the low temperatures variety Myronivska 808. Thus, the results indicate the possibility of recombining different levels of expression of these traits in genotypes by breeding efforts. This has great practical importance in farming, because in recent years the areas of crops harvested late (corn, sunflower, etc.) in the production conditions has significantly increased. It causes a shift in sowing dates of winter wheat to a later period. In this case, varieties Estafeta myronivska, Hratsiia myronivska, MIP Assol, and Balada myronivska are able to undergo sufficient hardening, to satisfy the vernalization requirement, and to form a high level of winter hardiness. Their relatively medium photoperiod sensitivity allows vegetation to be restored a little earlier in the spring and winter reserves of moisture to be used more effectively.

The influence of terbutryne (Igran 50) on the accumulation of choline in the grain of three winter wheat varieties ('Holme', 'Kranich', 'Winetou') was investigated in field experiments in the years 1977-1979. Igran 50 (50% S. A.) was applied to the soil in a weed control dose (4 kg/ha). Differences in choline content were found in the grain of the investigated wheat varieties. After application of the herbicide an insignificant decrease of the determined compound content was noted. These changes were dependent on the varieties of wheat and the meteorological conditions of plant vegetation. The climatic conditions, exercised a greater influence on the choline content in grain than the applied herbicide. For this reason it appears from the agricultural point of view that the effect of terbutryne provoking only an insignificant decrease of the determined compound content in the investigated material is of no greater practical importance.

The studies were carried out in laboratory conditions on the basis of the Agrotechnological Institute of Northern Trans-Ural State Agricultural University. The studies include 5 varieties of winter wheat grown in 2009-2011 in three agroclimatic zones of Tyumen Region: sub-regional (Nizhnetavdinsky state crop testing site), northern forest steppe (Yalutorovsky state crop testing site), southern forest steppe (Berduzhsky state crop testing site). Bashkirskaya variety – 10 (45 g) demonstrated the highest potential in the formation of a 1000 grain weight. The same variety has the highest range of variability (11.7 g) and the variability coefficient (10.9%) indicates average variability. Other varieties showed minor variability of characteristic (V = 8.7-9.9%). Winter wheat varieties varied in terms of average hardness, at the same time the level of values of all varieties (66-77%) corresponded to the standards of high classes according to GOST. Novosibirskayaaya 32 (61-93%) and Bashkirskaya 10 (60-86%) varieties were the most stable in forming the required value of characteristic. The average gluten content in a grain of winter wheat varieties was corresponded to the standards of the third class according to GOST. Novosibirskaya 32 variety (V = 8.5%) had minor variability of the characteristic, while other varieties demonstrated the average variability. A significant proportion of the effect of the “variety” factor on the variability of such features as a 1000 grain weight (56.5%), grain-unit (50.5%) and hardness (45.1%) was established. The amount of gluten depended more on the growing environment (35.5%) and interaction of factors (39.3%). The quality of gluten was much influenced by the growing environment (52.2%).

Winter Wheat Varieties

Experimental researches had been carried out during 2012–2016 in the crop rotation of Sumy National Agrarian University (SNAU) of the Ministry of Education and Science of Ukraine. Soils on the experimental field of SNAU – black soil typical deep, non-humusful medium-loam with high and medium provision with elements of mineral nutrition. The humus content about 3.9 %. The reaction of the soil solution is close to neutral (5.8). The analysis of the weather conditions of 2012–2016 researches was conducted on the basis of annual data provided by the meteorological station of the Institute of Agriculture of the North-East of the NAAS, located five kilometers from the experimental field of SNAU. The SNAU soils are classified in the second agro-climatic region of the Sumy region, which according to a long-term data is characterized by temperate continental climate with warm summers and not very cold winters with thaws. Average daily (average annual) air temperature during 2012–2016 fluctuated from +7.9 to +9.5 ºС, and the legth of the frost-free period was close to 230 days. Long-term indicator, precipitation falls within 597–600 mm, with most of it – in the warm period (April-October). In general, the weather conditions during the winter wheat vegetation periods differed from the average annual parameters of the temperature regime, the amount of precipitation and their monthly distribution. It should be noted the excess of temperature to the average long-term index, as well as a slight precipitation increasing. In general, it facilitated to a comprehensive evaluation of the studied Chinese varieties as for an adaptive ability under condition of Ukraine. The samples of Chinese winter wheat varieties which originated from the expeditionary gatherings conducted by V. A. Vlasenko in Gansu and Hebei provinces in (2000–2012) were the material for conducting researches. The cultivar Podolianka (the standard) was used in the study for comparison. The research was carried out using field, laboratory and mathematical-statistical methods. Phenological observations and records, evaluation and harvesting were conducted in accordance with generally accepted methods. The results of research as for adaptive potential of Chinese bread winter wheat varieties are presented. 50 new cultivars of Chinese origin were analyzed under the conditions of left-bank side of North-East Forest-Steppe of Ukraine: super-early varieties – 10 %; early ripening varieties – 54 %; middle-early varieties – 12 %; mid-ripening varieties – 24 %. As for the level of tolerance for winter conditions, all groups of alien crops were inferior to the standard (cultivar Podolyanka) though they had a great level of index (6.4–7.9 points). In general, Chinese cultivars under the conditions of the research were characterized by relatively satisfactory tolerance for winter conditions; 52 % of analyzed patterns wintered at the level of standard with 8 points. Among them: super-early varieties – 2 %; early ripening varieties – 20 %; middle-early varieties – 8 %; mid-ripening varieties – 22 %. As for the height of the plants we identified – from medium-sized (81‒110 cm) forms to dwarf (30-50 cm). The analyzed genotypes divided into medium-sized forms – 22 %, dwarf forms – 14 % and semidwarf forms – 64 %. There was a direct relation between: a plant height → group of ripeness (r = 0.96) → group of ripeness (r = 0.92) → resistance to overwintering (r = 0.78). Among the analyzed patterns high resistance against a group of diseases had the varieties: middle-early genotypes – Longzhong 10, Zhong mai 19, Shijra zhuang 8; mid-ripening genotypes – Longzhong 1, Longzhong 3, Longzhong 2, Longzhong 4, Longzhong 12, Longzhong 7; early ripening genotypes – DF529, Lankao 906, DF581, СА0175, Zhongmai 9, Shi 4185, Jimai 22, Shixin 733, Shimai 12. As for the crop better than the standard: early ripening varieties –Jimai 19, DF529; middle-early varieties – Shijiazhuang 8, Longzhong 10, Jingdong 8; middle-early varieties – NSA 97-2082, Longzhong 2, Longzhong 4, Longzhong 7, Longzhong 5, Longzhong 8, Longzhong 12, Longzhong 11, Longzhong 3. 16 % of analyzed cultivars distinguished by the totality of researched characteristics – DF529, Shijiazhuang 8, Longzhong 3, Longzhong 10, Longzhong 4, Longzhong 7, Longzhong 12, Longzhong 2.

The article substantiates the need to improve the elements of technology for growing varieties of soft winter wheat, taking into account the size of the seed material and weather conditions of the growing season. It is determined that along with varietal properties, the use of pre-prepared seeds for sowing has an impact on its sowing properties, field germination, growth and development of plants, their formation of elements of productivity and grain yield. The study was conducted on five registered varieties of soft winter wheat 'Tsarychanka', 'Karmelyuk', 'Sidir Kovpak', 'Dykanka' and 'Sanzhara' in the agro-climatic zone of the central part of the Forest-Steppe of Ukraine. The results of research showed that the highest field germination of seeds have the variety 'Karmelyuk' for sowing shallow and medium fraction of seeds (94 and 90%, respectively), and the variety 'Dykanka' - sowing medium and large fraction (95 and 86%, respectively). The percentage of germination of seeds of varieties 'Tsarychanka', 'Sanzhara' is almost at the same level 82 and 89, respectively. The highest indicators of elements of structure of an ear are found at the varieties 'Karmelyuk' - 30,5 pieces of grains in an ear, for its weight in an ear of 0,86 g, 'Dykanka' - 30,6 pieces of grains in an ear, for its weight in an ear 0, 87. The use of seeds of the middle fraction for sowing provided the highest yield of varieties 'Karmelyuk', 'Dykanka' which amounted to 4.7 t / ha. When sowing seeds of a large fraction, the highest yields were obtained by 'Dykanka' and 'Sanzhara' varieties - 4.8 and 4.9 t / ha, respectively. The aim of the study. To determine the influence of seed fraction on sowing qualities, variability of yield elements of soft winter wheat varieties. The experiment was conducted in the central forest-steppe of Ukraine, using general research methods studied in agronomy The material for the study were winter wheat varieties of Poltava State Agrarian Academy: "Tsarchanka", "Karmelyuk", "Sidir Kovpak", "Dykanka" and "Sanzhara". Sowing of the studied varieties was carried out with seeds selected on sieves and divided into fractions: shallow (1), medium (2), large (3), and mixture (4). Agrotechnics in the study are generally accepted for the soil-climatic zone of the Forest-Steppe of Ukraine. The increase in the weight of 1000 grains was significantly influenced by sowing with the middle fraction of seeds, which is characteristic of the variety 'Sidir Kovpak' (50.4 g), large - 'Tsarychanka' (52.5 g), 'Dykanka' (49.2 g) and 'Sanzhara' (48.4 g), for the variety 'Karmelyuk' the weight of the grain increases when sown with a mixture of seeds (52.0 g). It was determined that the size of the seed material had an impact on the elements of the structure of the ear of corn and grain size. Thus, the variety 'Tsarichanka' formed 26.8 pieces. grains in the ear, for its weight of 0.65 g when sown by the average fraction of seeds, variety 'Karmelyuk' on the same variants of the experiment, respectively - 30.5 pcs. and 0.86 g, grade 'Sidir Kovpak' - 27.4 pcs. and 0.85 g, 'Dykanka' - 30.6 pcs. and 0.86 g. For these varieties, the dependence is established: sowing in shallow and large fractions, as well as a mixture of seeds reduces the number and weight of grains from the ear. In the variety 'Sanzhara' revealed a maximum increase in the number of grains from the ear to 26.8 pieces. and the mass of grain from the ear of 0.88 g in the options for sowing a large fraction of seeds Yields of the studied varieties of winter wheat depending on the size of the seed material varied in the range from 3.08 to 4.86 t / ha, with the highest value in option 3 (large seeds) in the varieties 'Sanzhara' (4.9 t / ha) and 'Dykanka' (4.8 t / ha), on option 2 (average seed) 'Karmelyuk' (4.67 t / ha), 'Sidir Kovpak' (4.29 t / ha) and 'Tsarychanka' - 4 .0 t / ha. It was found that the yield of all studied varieties of winter wheat has a strong correlation with seed size and number of grains in the ear (r> 0.70), the average correlation between the weight of 1000 grains and grain yield was found in varieties' Tsarychanka ',' Karmelyuk 'and' Dykanka '(r = 0.31… 0.69). In the variety 'Sanzhara', the weight of the grain from the ear and the yield have a rectilinear correlation of medium strength.

Abstract. Wheat is a crop with a very long growing season, during which it is subjected to prolonged exposure to many environmental factors. For this reason, the interaction of genotype with conditions is very common for any character of wheat. This study aims to determine whether the grain yield is affected by the change of the ear emergence date (EED) in various environments. In a four-year period, 30 current for national real grain production winter wheat varieties were studied. The EED and grain yield (GY) were studied as quantitative traits within five locations of the country having various soil and climatic conditions. Using several statistical programs, genotype x environment interaction of two traits was analyzed. The emphasis on data analysis was whether changes of traits due to the conditions were related and that the optimization of the ear emergence date could serve as a breeding tool for increasing grain yield. The date of ear emergence and grain yield are traits that are reliably influenced by growing conditions. The change in the date of emergence is mainly of the linear type, while the grain yield shows linear and nonlinear type changes in the same environmental conditions. It was found that the key roles in the change of characteristics are the conditions of the year, with the relatively weakest impact of the genotype on them. There is a positive relationship between the two traits, although their change depends on environmental factors. Although they change to different degrees and in relation to each other, there is a positive correlation between them. The more favorable the environmental conditions, the weaker the relationship between these two traits and vice versa. Under changing climatic conditions, the change in the relationship between the two traits is a signal of the need to create different varieties by date of ear emergence in order to obtain higher yields in the future.

Purpose. Investigate the features of adaptive ability of winter wheat varieties of various ecological and geographical origin and reveal the mechanisms of formation of such valuable features as the nature of grain and yield. Methods. In this work, a systematic method of the variants placement was used; field methods – for conducting phenological observations and accounting, laboratory (for establishment of collection varieties), biometric and measuring-weight (for accounting the productivity and yield), mathematical and statistical (objective evaluation of the obtained experimental data). Results. The research was conducted in the research field of the Department of Genetics, Plant Breeding and Biotechnology of Uman National University of Horticulture in 2019-2020. Over the years of research, the nature of grain has changed somewhat. Thus, in 2019, in the varieties that were created in the southern Forest-Steppe, it ranged from 733-766 g/l, while in 2020 these values were 719-748 g/l. In wheat varieties created for the Steppe natural zone, the figure for 2019 was in the range from 743 to 791 g/l, in 2020 it was 719-774 g/l. In 2020, the yield of winter wheat grain of the SN Kombin variety (Forest-Steppe zone) was the highest and amounted to 748 g/l, which is more than the indicators of the Columbia variety and the standard by 42 and 28 g/l respectively. Of the varieties created in the southern Forest-Steppe, Columbia had the lowest yield – 4.1 t/ha. The SN Kombin variety exceeded the Smuglyanka variety by 2.0 t/ha. High grain yield was in the Samurai variety, created in the Steppe zone, which was 10.3 t/ha, or more by 9%. Conclusions. The highest indicator of grain yield was found in the variety Anter, which was 774 g/l, which is 59 g/l more than the control. During the years of research, the weight of 1000 grains in the Samurai variety was the highest and amounted to 47.1 g, which is higher than the standard by 1.3 g. High grain yield was in the Samurai variety, created in the Steppe zone, which was 10.6 t/ha , or by 1.4 t/ha more compared to the standard. Variety Anter formed a 9.2 t/ha grain yield (at the level of the Smuglyanka variety). Thus, on average, for two years of research, the highest yields showed the SN Kombin and Samurai varieties, which amounted to 10.9 and 10.3 t/ha respectively. Other varieties of wheat, such as Smuglyanka and Anter, had almost the same yield – 8.9-8.8 t/ha.
