The Impact

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.

Aim. Identification of new winter wheat breeding material developed in Kharkiv by electrophoretic patterns of storage proteins to select the most promising lines. Methods. Protein fractionation was performed by APAG- and SDS-electrophoresis. Results. The genotypes of winter wheat samples of the competitive variety trial at seven storage protein loci Gli-A1, Gli-B1, Gli-D1, Gli-A3, Glu-A1, Glu-B1, Glu-D1 were studied. We identified eight alleles at the Gli-A1 locus, seven at Gli-B1, five at Gli-D1, four at Gli-A3, five at Glu-B1, three at Glu-A1, and two at Glu-D1. Most of the identified alleles are typical for Ukrainian winter wheat varieties. Along with them, theree were lines with introgressed alleles marking for the wheat-rye translocations 1AL/1RS and 1BL/1RS. The biotype of the line Erythrospermum 484-19 carries an introgressed allele from Ae. tauschii at the Gli-D1 locus. Conclusions. According to field and laboratory trials of samples, there were neither significant advantages nor disadvantages of lines with wheat-rye translocations compared to lines without translocations (typical for the East Forest-Steppe zone). The promising line of the use of the 1AL/RS or 1BL/RS translocations (carrying disease resistance genes) is their coupling with the allele Glu-B1al associated with high grain quality. Keywords: winter wheat, storage proteins, alleles, translocations.

The assessment of productivity and the parameters of adaptability allowed to use and perspective mid-season and mid-late varieties of spring wheat in the conditions of the Northern Trans-Ural region carried out. The varieties were tested in 2014-2016 on the steam predecessor in three climatic zones: subtaiga (II zone), northern forest-steppe (III zone) and southern forest-steppe (IV zone). The greatest interaction a genotype-environment is noted when calculating correlation dependence between productivity of varieties in various years of their test in the conditions of the southern forest-steppe zone (from r=-0,07±0.28 to r=0,41±0,25). Assessment of productivity and parameters of adaptability of spring wheat varieties in 9 environments (3 years x 3 GSU) has shown that Aviada allowed to use characterized the greatest maximum and average productivity in group of mid-season varieties (respectively 5,86 and 3,78 t/hectare), and in the mid-late group – a perspective Quintus (respectively 6,98 and 4,58 t/hectare). The considerable variability of productivity is noted.  Its size was from 23,0 % (Ikar) to 29,9 % (Aviada) in group of mid-season varieties, and at the mid-late group – from 25,6 % (Riks) to 31,6 % (Quintus). Resistance to stress of varieties was low irrespective of group of their ripeness. Ikar (-2,32) had the greatest indicator of resistance to stress in group mid-season varieties, and in the mid-late group – Riks (-2,54). Aviada (4,24 t/hectare) was characterized the greatest average productivity in contrast conditions in mid-season group and in the mid-late group – Quintus (4,73 t/hectare). Three groups of varieties were allocated on responsiveness for change of conditions:  high responsiveness (mid-season – the Lutescens 70, Aviada; mid-late – the Melody, Quintus), plastic (mid-season – Chernyava 13, Skent 3, Omskaya 36, Tyumenskaya 25, Tyumenskaya 29; mid-late – Ingala, Yamalskaya) and poorly responsiveness (mid-season – Ikar, Sigma; mid-late – Riks, the Stepnaya Niva). The low gomeostasis is revealed at all varieties irrespective of group of ripeness. The variety Ikar (Hom=6,59) was the best on a gomeostasis in mid-season group, and at the mid-late group – Riks (Hom=5,48). In general all varieties were characterized by the low general adaptive ability (GAA). Its rather high values in group of mid-season varieties are revealed at Aviada (OAC=0,19), and at the  mid-late group – Quintus (OAC=0,50). Tyumenskaya 25 and Tyumenskaya 29 are recognized the best mid-season varieties in the conditions of the Northern Trans-Ural region on the basis of complex assessment of productivity and parameters of adaptability, and at the mid-late group – Melody and Ingala.

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.

On the basis of summarizing the results of many years of experience about environmental study of varieties and breeding varieties of spring wheat, we revealed the peculiarities of influence of plants’ assimilation apparatus parameters on the productivity level of early ripening, middle- and late ripening varieties in the forest-steppe zone of Orenburg Urals. These varieties should be used to create hybrid forms of spring wheat with optimal parameters of photosynthetic surface. This will better in solution the selection issues on efficiency in the forest of the Southern Urals. As a result, during the study of the influence of the size of the surface to the grain photosynthetic productivity level of wheat varieties, we found that in this case with an increase in the parameters of the assimilation apparatus, there is an increase of yields up to a certain limit, then a further increase in the size of the photosynthetic surface leads to lower yields. This pattern is clearly related to the fact that the overgrowing foliage due to worsening conditions for leaf photosynthetic activity, the rate of photosynthesis decreases. The following studied varieties of spring wheat have optimal parameters of the photosynthetic index: Volgouralskaya, Varyag, Kinelskaya 59, Logachevka, Lyuba, Prokhorovka, Solveig, Tulaykovskaya 1, Tulaykovskaya stepnaya and Enita. These varieties should be used to create hybrid forms of spring wheat with optimal parameters of the assimilation apparatus.
