Purpose and objectives. To evaluate the effect of sorting seeds by size on their quality indicators: germination energy, laboratory germinability and 1000-grain weight. Materials and methods. The experiments were carried out in the experimental field of the Plant Production Institute named after V.Ya. Yuriev of NAAS in accordance with the field experimentation method in 2016–2018; 26 winter bread wheat lines and varieties were studied. The varieties and lines were grown in variety trial experiments; the plot area was 10 m2. Seeds were separated on sieves of a laboratory separator RLU-3; the 1000-grain weight was measured; the laboratory germinability and germination energy were determined. Results and discussion. When winter bread wheat seeds are sorted on sieves, they are separated into fractions with various 1000-grain weights. The separated fractions of winter wheat seeds have different sowing qualities. The 2.5 x 20 mm seeds and 2.8 x 20 mm seeds are of the best quality (germination energy, germinability). It was found that in 2016–2018, the germination energy, laboratory germinability and 1000-gain weight changed depending on the growing conditions. They were the highest in 2017. The varieties with a high 1000-grain weight have been identified: Doskonala, Pryvablyva, Smuhlianka, and Haiok. The highest germination energy and germinability were intrinsic to varieties Yednist, Harmonika and Bunchuk. Yednist (93.3%), Harmonika (94.3%), Metelytsia Kharkivska (94.5%), Bunchuk (94.7%), Alians (93.3%), Podolianka (92.5%), Patriotka (93.6%), Zapashna (93.3%), Dyvo (93.7%), Doskonala (93.6%), Krasa Laniv (94.0%), Smuhlianka (93.1%), and Erythrospermum 408-13 (93.7%) had a high germinability of small seeds (2.2 x 20 mm). To clean these varieties, especially in years with low seed yields, it is recommended to use seeds of the standard size (2.2–2.5 x 20 mm). Conclusions. The relationships between the grain size and sowing qualities of seeds have been established. Separation of seeds is an effective technological method allowing for selection of top-quality seeds

Aim. To compare winter bread wheat accessions of different origin for spike productivity elements and yield capacity. Results and Discussion. 104 winter bread wheat accessions from 10 countries were studied. We distinguished, an accession from Turkey, SWW 1-904 (12.8 cm) due to its long spike. The largest number of spikelets was recorded in accessions SWW 1-904 (TUR), Veha (RUS) and Pamiatі Hіrka (UKR) - 21 spikelets. Turkish accession SWW 1-904 was noticeable for the grain number per spike. The greatest spike density was observed in accession Zluka (UKR) - 2.5 spikelets / cm. The spike weight and grain weight per spike were the highest in SWW 1-904 (TUR): 6.0 g and 4.5 g, respectively. Accessions Lehenda Myronivska (0.81), Prydniprovska (UKR), Kuma, Yunona, Avgusta (RUS) (0.80) had the highest index of spike productivity. The 1000-grain weight of 55.0 g was recorded in intensive variety SWW 1-904 (TUR). Accessions from Ukraine, Darynka Kyivska and Raihorodka combined high winter hardiness (9 points) with high yield capacity (955 g/m2). Conclusions. Thus, winter bread wheat accessions that are valuable starting material for developing new varieties with a set of important economic features, were identified. They can increase the breeding efficiency and accelerate the breeding process.

The current paper has presented the study results of SDS-sedimentation and grain quality indicators of the winter bread wheat varieties in an interstation variety testing from the research institutions of the Russian Federation, Ukraine and France. The research work was carried out in 2017–2019 in the field of the laboratory for breeding winter bread wheat, the forecrop was maize for grain. The purpose of the research was to estimate SDS-sedimentation, protein percentage in grain, quantity and quality of gluten in the winter bread wheat varieties of interstation variety testing, for the subsequent introduction of the best samples in the breeding process aimed at improving grain quality. Grain quality indicators of the winter bread wheat varieties were identified in the laboratory for biochemical estimation of breeding material and grain quality using IR spectroscopy on ‘SpektraStar 2200’ analyzer. There was established that according to the SDS-sedimentation most of the samples corresponded to strong wheat (50–63 ml). There have been identified the genotypes with the highest values of this trait, such as ‘Shef’ (58 ml), ‘Nakhodka’ (59 ml) and ‘Don 107’ (61 ml). The largest gluten content in grain was identified in the varieties ‘Don 107’, ‘Shef’, ‘Kavalerka’, ‘Timiryazevka 150’ and ‘Nakhodka’ (25.5–26.2%). The largest protein percentage in grain has been identified in the varieties ‘Don 107’, ‘Shef’, ‘Aksinya’, ‘Nakhodka’ and ‘Timiryazevka 150’ (12.5-12.8%). The varieties ‘Don 107’, ‘Shef’, ‘Nakhodka’ and ‘Timiryazevka 150’ were identified according to the studied traits and were recommended to be involved in the breeding process as parental forms.

A field trial was conducted at Abu-Ghraib Research Station-Agricultural Research Directorate-Ministry of Agriculture during the growing seasons of 2012-2013 and 2013-2014. The objective was to investigate the effect of source-sink Regulation on grain yield  and its companents of five bread wheat cultivars (Triticum aestivum L.). Randomized complete block design with the arrangement of split-plots with three replicates was used. Bread wheat cultivars (Bohooth-22, IPA 99, Abu-Ghraib-3,Al-Fath and Al-Rasheed) occupied the main plots while treatments of source-sink relationship regulation occupied the sub-plots. They included eight treatments: Con. control (Con.), S1 (removal of lamina of the flag leaf of main stem), S2 (removal of laminas of the leaf  beneath the flag leaf), S3 (removal of both lamina of the leaf  and the leaf under flag leaf), S4 (removal of upper third spikelets),S5 (removal of median third spikelets), S6 (removal of lower third spikelets) and S7 (removal all spikelets from one side of spike) . Characteristics of plant height, flag leaf area, spike length, no of spikelet per spike, spike weight, and grain yield and its components were measured and estimated. Results of the present study indicated the followings:  Cultivar (Bohooth-22) gave the highest 1000 grain weight (35.70 and 35.31 g) the highest grain yield (5.467 and 5.148 t.ha-1) in both seasons, respectively compared with Abu-Ghraib3 and Al-Rasheed cultivars which gave lowest grain yield (4.918,4.364, 4.239 and 4.352 t.ha-1) in both seasons, respectively and then less 1000 grain weight (30.15, 32.66, 32.61 and 32.77 g), in both seasons, respectively. Treatment (Con.) i.e no modification of source-sink relationship gave the highest grain yield (5.93 and 5.66 t.ha-1) in both seasons, respectively. Treatments of regulation source (S1 and S3)gave grain yield (4.909, 4.698, 4.621and 4.356 t.ha-1), respectively while (S5) treatment gave the lowest grain yield (4.203 t.ha-1) in the first season and (4.061 t.ha-1) in the second season. This indicates that sink regulation treatment was the most influencial in reducing grain yield than the source regulation treatment, especially, treatment (S5) in both seasons where the  median third of spikelets had been removed due to the reduction of spike growth rate (3.18 and 2.49 g.day-1) in both seasons compared with the (Con) treatment which gave the highest values of spike growth rate (3.91 and 3.12 g.day-1) in both seasons, respectively which resulted in the reduction of dry matter translocation in the (S5) treatment (1.87 and 1.74 g.day -1) and consequently in the reduction of 1000 grain weight (30.09 and 31.199) compared with (34.99 and 37.12 g) in the (Con.) treatment in both seasons, respectively.

There have been presented the results of a comparative estimation of recombinants developed on the basis of two commercial varieties (‘Sibirskaya 17’ and ‘Novosibirskaya 31’) hybridized with ‘Thatcher Lr19’ and ‘Thatcher Lr24’. Recombinants were evaluated in the field conditions in 2016, 2017 and 2020. The purpose of the current study was to identify the effect of translocations from Thinopyrum elongatum on the manifestation of productivity elements in recombinants of spring bread wheat developed on the basis of two commercial varieties. The analysis of the genetic composition of the Puccinia triticina populations in Western and Eastern Siberia did not identify genes which were virulent to resistance genes Lr19, Lr24, Lr28, Lr41, Lr47, Lr45 LrSp, Lr6Agi 1 and Lr6Agi 2. The recombinants developed on the basis of the variety ‘Sibirskaya 17’ (the variety productivity was 398.3 g/m2 , grain weight per head was 1.35 g, 1000-grain weight was 37.8 g) were characterized by the severity of the main agronomically valuable traits at the level of the recipient variety, or significantly lower (productivity was 271.5–327.8 g/m2 , grain weight per head was 1.03–1.16 g, 1000-grain weight was 32.5–36.4 g). The recombinants carrying translocations (the length of the period ‘sprouts-heading’ was 44.4 and 44.5 days, grain weight per head was 1.20 and 1.24 g) developed on the basis of the variety ‘Novosibirskaya 31’ (with 42.4 days, 1.02 g) have demonstrated a significant increase in the length of the period ‘sprouts-heading’ and grain weight per head in comparison with the recombinants without translocations (41.6 and 43.6 days, 0.99 and 1.10 g). On average over 3 years, 12 recombinants hybridized from the combination ‘Novosibirskaya 31 x Thatcher Lr19’ produced higher yields (355.6–427.5 g/m2) than those of the recipient variety (301.5 g/m2), both with (6 pcs.), and without (6 pcs.) a translocation.

Aim. To determine the stability and plasticity of the grain weight per spike, 1000-kernel weight and yield of mid-high and semi-dwarf winter bread wheat accessions. Results and Discussion. We determined the stability and plasticity of the grain weight per spike, 1000-kernel weight and yield of mid-high and semi-dwarf winter bread wheat accessions. The meteorological conditions during the vegetation periods in 2015-2018 made it possible to differentiate winter bread wheat accessions by stability and plasticity of the grain weight per spike, 1000-kernel weight and yield. The best winter bread wheat accessions of the NCPGRU’s collection, which were distinguished by grain weight per spike, 1000-kernel weight and yield, were evaluated for their stability degree (Sd) and plasticity level by regression coefficient. It was found that the proportion of accessions with high homeostaticity (bi <1) for the traits under investigation, which was most typical for mid-genotypes, was 70.6% for the yield, 64.7% for the 1000-kernel weight and 58.8% for the grain weight per spike, which is important for breeding for adaptability. Sources of high homeostaticity with a regression coefficient of <1 for the grain weight per spike (Zorepad Bilotserkovskyi, Anatoliia (UKR)); 1000-kernel weight (Krasa Laniv (UKR); Ilona (SVK)); yield (Pochaina, Krasa Laniv (UKR); Adel, Kazachka (RUS); OR2070011 (USA); Ilona (SVK), Darunok Podillia (UKR)) were singled out. In addition, we selected accessions with a wide environmental response (bi> 1), which can best fulfill their yield capacity under improved growing conditions or on an increased soil fertility, for the grain weight per spike (Zorepad Bilotserkovskiy, Anatoliia (UKR)); 1000-kernel weight (Harmonika, Prynada (UKR), Moskvich (RUS), Aran (AZE)); yield (Biloretskovskyi Zorepad, Prynada (UKR), Morozko, Vid (RUS)). Conclusions. The study of collection material of different eco- geographical origin enabled us to identify new sources of grain weight per spike, 1000-kernel weight and yield with increased environmental plasticity and stability, the use of which in breeding programs will contribute to the development of new highly productive and more valuable genotypes. Sources of high homeostaticity in winter bread wheat are valuable starting material to develop new highly adaptive varieties.

SUMMARYCCC applied to bread wheat, in 1967 and 1968 as a foliar spray at 1·40 and 2·28 kg./ha. a.i., prevented and/or delayed lodging to some extent. However, this effect was small and complete control of lodging seems to be unlikely, even when using large amounts. CCC increased grain yields, by 1·5 to 10·9 qu./ha., depending on the extent to which lodging was reduced. Significant depressions in yield were obtained, presumably owing to an observed increase incidence in ear diseases, particularly Septoria nodorum. The increase in grain yield was due mainly to an increase in 1000 grain weight and grains per ear, whereas the effect on tillers per unit area was slightly negative. Where no lodging occurred, there was a slight but non-significant tendency for increasing grain yields after CCC treatment.

Grain Size And Shape

Grain characteristics, particularly grain weight, grain morphology, and grain protein content (GPC), are important components of grain yield and quality in wheat. A set of 98 bread wheat landraces from different geographic regions of Iran were used across 2013-2014 and 2014-2015 to determine the phenotypic diversity and relations between thousand grain weight (TGW), grain morphology and grain quality. A high-throughput method was used to capture grain size and shape. The genotypes were significantly different (P < 0.001) for all traits which reflects the high levels of diversity. A moderate to high broad sense heritability was found for all traits and ranged between 0.68 and 0.95 for grain yield and factor from density (FFD), respectively. Significant positive correlations were observed between TGW and grain size (or shape) exception of aspect ratio (AR) and roundness. However, grain quality traits, especially GPC had significant negative correlation with TGW. Based on stepwise regression analysis by taking TGW as dependent variable, grain volume, FFD, width, perimeter and Hardness Index (HI) were recognized as the most important traits and explained more than 99.3% of total variation of TGW. The path analysis revealed that FFD has maximum direct effect on TGW followed by volume, whereas perimeter and width had relatively less direct effect on TGW. According to cluster analysis, landraces separated into 5 clusters, and cluster III and IV had the maximum and minimum average for the most traits, respectively. Our study provides new knowledge on the relations between TGW, grain morphology and grain quality in bread wheat, which may aid the improvement of wheat grain weight trait in further research.
