Aim. The aim of the study was to investigate genetic variability of storage protein loci in European common winter wheat varieties licensed for growing in Ukraine in 2018 year. Methods. SDS and APAG electrophoresis were used to identify genotypes at the high-molecular-weight (HMW) glutenin loci Glu-1 and gliadin loci Gli-1. Results. Genotypes at the gliadin loci Gli-A1, Gli-B1, Gli-D1 and HMW glutenin loci Glu-A1, Glu-B1, Glu-D1 were identified in 48 winter common wheat varieties. A total of twenty gliadin alleles (including 10 at the Gli-A1, 4 at the Gli-B1, 6 at the Gli-D1 loci) and eleven HMW-GS alleles (including 3 at the Glu-A1, 5 at the Glu-B1, 3 at the Glu-D1 loci) were revealed. Differences in frequencies of alleles at storage protein loci were established. Conclusions. The high level of allelic variation was observed at the Gli-1 and Glu-1 loci in European common winter wheat varieties. Predominant alleles were revealed: Gli-A1о, Gli-A1а, Gli-A1f, Gli-B1f, Gli-D1b, Gli-D1d, Glu-А1c, Glu-А1a, Glu-B1с, Glu-B1d, Glu-D1d, Glu-D1a. Differences in frequencies of alleles at the storage protein loci between European and Ukrainian common winter wheat varieties were found.

Aim. The aim of the study was to investigate genetic variability of gliadin-coding loci Gli-A1, Gli-B1, Gli-D1 in Ukrainian winter common wheat landraces and obsolete varieties. Methods. APAG electrophoresis of gliadin was used to identify genotypes at Gli-1 loci. Results. Diversity at the Gli-1 loci of 41 winter common wheat landraces, including local varieties Krymka, Banatka, Girka, Theyka, and 13 obsolete winter common wheat varieties, were studied. A total 31 gliadin alleles (including new 7 alleles) were revealed. There are 11 alleles at the Gli-A1 loci, 14 - at the Gli-B1, 6 -at the Gli-D1. Differences in frequencies of gliadin alleles were established. Conclusions. The high level of allelic variation at the Gli-1 loci was observed in Ukrainian winter common wheat landraces. Predominant alleles were revealed: Gli-A1m (46,8 %), Gli-A1d (21 %), Gli-B1b (47,1 %), Gli-D1g (45,8 %), Gli-D1a (33,3 %), Gli-D1j (13,9 %). In genotype of modern Ukrainian winter common wheat are present only 3 of them - Gli-B1b, Gli-D1g, Gli-D1j, which positively relate to dough quality.

In this study, genetic variability was investigated among 50 winter wheat varieties (Triticum aestivum L.) which are grown in parts of Croatia, Hungary, Serbia and Slovenia according to 22 morphological characteristics used for DUS (distinctness, uniformity and stability) testing. The average Dice similarity coefficient was 0.371. The determined similarity coefficient was in range 0.083 - 0.776. A significant variability of 6.21% in the breeding programs according to period was determined as well as significant variability of 3.10% between breeding programs. The UPGMA clustering divided investigated varieties into four main clusters. Based on data analysis, most distant varieties with best morphological characteristics were found which will provide valuable resource of new parent's combinations in future breeding programs. This paper also provided valuable assessment of morphological characteristics to define distinctness criteria in the DUS examination of wheat.

Abstract Dual-purpose wheat (Triticum aestivum L.) systems increase farm sustainability by diversifying on-farm income. While these systems are common in the Southern Great Plains of the United States, they are not often utilized in the Southeast. This study aimed to evaluate pre- and post-grazing herbage mass (HM) of four winter wheat varieties managed under a dual-purpose grazing and grain production system. The winter wheat varieties evaluated were generic feed-type wheat (mixed variety, Feed), seed-type wheat (‘GA Gore’) and two forage-type varieties, ‘AGS 2024’ (AGS) and ‘Pioneer 26R41’ (Pioneer). The experiment was a completely randomized block design with n = 4. Each plot was randomly assigned either as no-grazing (CON) or grazing (GF2). Plots were grazed with cow-calf pairs that were fasted 24 h before each grazing event. Grazing was considered complete when the average stubble height was 10 cm. Herbage mass was determined using three 0.1m2-quadrats per plot and clipping to a 10 cm stubble height before (PreG) and after (PostG) each grazing event. Forage samples were then dried at 45°C for 72 h. Data were analyzed using PROC GLIMMIX of SAS (SAS Inst., Cary, NC). Differences were declared at P < 0.05. Initial HM was greater for PreG than PostG (883 and 615 kg/ha, respectively; P < 0.01). Prior to grazing, AGS (1204 kg/ha) was greater (P < 0.02) than all other varieties. Pre-grazing, there were no differences among the other varieties (776 kg/ha; P > 0.14). Post-grazing, AGS had a greater HM than Seed (788 and 391 ka/ha, respectively; P = 0.04), while all other varieties were intermediate (642 kg/ha). Herbage mass was affected by grazing frequency with CON being greater (P < 0.01) than GF2 (993 and 691 kg/ha, respectively). These results indicate that both wheat variety and grazing treatment had an effect on dual-purpose wheat herbage mass.

The influence of contrasting trophic conditions of vernalization on the allelic state of the Vrn genes and development rates of two winter wheat varieties, Mironovskaya 808 and Olvia, was investigated. Vernalization was carried out during 45 days at the temperature 4 ± 1°С under different conditions of trophic support. Whole seeds with endosperm and isolated buds, with added water and 3% solution of sucrose, were vernalized. The allelic state of the Vrn genes was identified by PCR using allele-specific primers on the sprouts at different phases of vernalization – 15, 30, and 45 days. Phenological observations were carried out by determining of the transition to the generative development of wheat plants, cultivated from the vernalized sprouts. According to the results obtained, it was established that the recessive state of the genes Vrn-A1, Vrn-B1 and Vrn-D1 was unchanged in all variants of the two winter wheat varieties on the 15th and 30th days of vernalization. After 45 days of vernalization, the recessive and dominant alleles in sprouts, vernalized under normal trophic conditions and with added 3% solution of sucrose, were detected at the Vrn-B1. All variants of wheat plants grown from vernalized sprouts under contrasting trophic conditions were transferred to the generative phase, but at different times. It could indicate an epigenetic regulation vernalization process. It was established that different trophic conditions during vernalization affected the changes of the allelic state of the Vrn-B1 gene and determined the transition to the generative development of winter wheat.

Abstract Winter wheat wholemeal is an important component of the human diet and may be a significant source of antioxidants. The objective of this study was to determine individual phenolic compounds in five winter wheat varieties: ‘Fredis’, ‘Edvins’, ‘94-5-N’, ‘Skagen’, and ‘SW Magnific’ wholemeal, grown according to organic and conventional agricultural practices. Ten phenolic compounds (vanilin, rutin, catechin hydrate, quercetin, p-coumaric acid, ferulic acid, 3.4-dihydroxybenzoic acid, 2-hydroxycinnamic acid, trans (3)-hydroxycinnamic acid, and gallic acid) were detected using high-performance liquid chromatography (Schimadzu Prominence HPLC). Catechin hydrate and quercetin were the main phenolic compounds in the grain of all tested winter wheat varieties. Significant differences (p < 0.05) among the analysed winter wheat cultivars in the concentration of individual phenolic compounds were observed. Concentrations of vanillin in organic and conventional winter wheat wholemeal were significantly lower (0.28 ± 0.02 to 0.65 ± 0.04 µg·g−1 DW), although the differences in the levels of phenolic were not large. The obtained results showed a statistically significant trend (p < 0.05) towards higher levels of phenolic compounds in organic wheat wholemeal samples.
