The determination of flour end-use quality of progenies is a routine process in high-quality wheat breeding program. Traditional determination involves larger amount of flour and specific instruments, meanwhile, is expensive and time-consuming. A rapid and accurate method which could predict the quality of early generation wheat lines is in high demand in the wheat breeding program. Clarifying the relationships among different prediction indexes is the prerequisite for devising a new prediction method screening the high-quality progenies. This study aimed to clarify the correlations between SDS sedimentation value, SIG and SRCs for both wholemeal flour and flour, as well as to study which parameter could be applied to predict the flour quality of spring wheat rapidly and conveniently. The result of the study showed that WSRC correlated significantly with all the parameters determined, the four different SRCs varied significantly between hard wheat and soft wheat, while SDS sedimentation value and SIG showed no significant difference between hard wheat and soft wheat. SRC test may provide a convenient method for predicting the quality of early generation wheat lines in wheat breeding.

A number of F6 winter common wheat lines that carry the wheat-rye 1BL/1RS translocation of the Kavkaz type with respective resistance genes linked with high bread-making quality allele Glu-B1al have been developed via marker selection among F2 plants from the cross B16 × Odesskaya krasnokolosya. The SDS-sedimentation value in these lines proved to be in most cases similar to that of the cultivar Bezostaya 1. The lines may be used as a source of the 1BL/1RS translocation linked with the high-quality allele Glu-B1al, which compensates for the negative effect of this translocation on bread-making quality.

Grinding Time

A test for screening early generation wheat lines for kernel hardness is described. The test is rapid, uses small samples and is easily performed. Resulting grinding times can be used to classify wheat according to hardness, to detect possible seed damage, to give an estimate of the potential milling and baking quality of wheat and to make quality screening more efficient. Differences between hard and soft wheats are large so that protein content, kernel size and percent moisture have little effect on the use of grinding time as a quality screening test in wheat breeding programs in western Canada.

<p>In this article, we proposed a rationale for choosing the seeding aggregates to improve the quality of ordinary spring wheat sowing in the moderate arid steppe of the Altai Territory. We determined the actual values and variability of spring wheat sowing quality indicators when different sowing units were used. A comparative evaluation of sowing aggregates was made on the basis of a generalized parameter that characterizes the quality of sowing taking into account their equalization. The study compared the following technologies and seeding machines: direct seeding with the use of the EPPK-2.5 complex; zero technology (No-Till) with sowing complex Condor; traditional technology of cultivation of crops with autumn processing with PG-3-5 gun, presowing processing of APK-7.2 and sowing of SZP-3.6A. The compared variants were randomly located, the sowing was carried out in the third decade of May, the rate of sowing was 5 million virgin grains per hectare, spring soft wheat "Altai 70". Determination of quality parameters of sowing (depth of seeding, the number of plants, plant height and their statistics) were conducted in the 2nd decade of June. During 2013-2016, SZP-3.6A crops had the advantage from the number of shoot and it was 346.1 pcs / m2, which is by 1.84 and 2.34 times was higher than Condor and EPPK-2.5 respectively. The height of plants also had an advantage of SZP-3,6A – 282.6 mm, which was higher by 25.4 mm and 71.2 mm than in Condor and EPPK-2.5 respectively. Each indicator of the quality of sowing was characterized by fluctuated magnitude. High coefficient of variation indicated low quality of sowing. We calculated the equalization coefficient for each parameter to assess the uniformity of crops performed by each machine. The SZP-3,6A seeder exceeded the compared seeding complexes for all three parameters, which indicated higher seed uniformity than Condor and EPPK-2.5. Comparative evaluation of the seeding machines Condor and EPPK-2.5 was ambiguous. At the seeding unit EPPK-2.5, the leveling factor was 12.3% higher than in Condor, the seeding rate was 17.8% lower in comparison with Condor, and the plant height was insignificantly (by 2.1%) lower than Condor.</p><p>We suggested a generalized leveling factor to evaluate the sowing aggregates in terms of the quality of sowing, i.e. radius vector drawn up to point A, characterized by the coordinates A (depth of embankment, number of sprouts, and plant height). A better seeding was obtained with the SZP-3.6 A seeding unit (84.2%). The lowest quality parameters for sowing were obtained from the seeding complex EPPK-2.5 (75.9%). Crops with this complex were characterized by the greatest uneven quality of sowing, which requires a correct justification for both the sowing rate, the method of sowing and the width of the rows of cultivated crops according to the technology applied to specific conditions.</p>

The results of two–year (2018–2019) studies on the effect of various seeding rates and nutritional backgrounds on the yield and grain quality of two types of spring wheat – soft wheat and emmer wheat (spelt) – are considered. The agrochemical characteristic of the gray forest soil of the experimental plot is as follows: the humus content in the layer of 0–20 cm was 2.9–3.4 % (Tyurin method), mobile phosphorus amount was 176–241 mg, exchange potassium amount was 77–109 mg/kg of soil (Kirsanov method). The degree of saturation with bases was 85.2–87.7 %, the pH of the salt extract was 5.6–5.8. Agrometeorological conditions of 2018–2019, on the whole, met the requirements for early spring crop seeding, HTC (hydrothermal coefficient) was 0.85–1.2. Two levels of mineral nutrition were studied in the experiment (natural background, without fertilizing, NRK for the planned grain yield of 3 t/ha), four seeding rates against each nutrition background: 4, 5, 6 and 7 million germinating seeds per 1 ha. The seedling completeness in both types of wheat over an average of 2 years depended on the seeding rate, regardless of the background of nutrition. In soft wheat of Ulyanovskaya 105 variety, against a natural background, with an increase in the sowing rate from 4 to 7 million germinating seeds per ha, the seedling completeness decreased and amounted to from 82.5 to 76.3 %, in spelt, it was 84.7–78.6 %. On a fertilized ground it was, respectively, 83.4–78.0 and 84.1–77.6 %. Good preservation of plants in both types of wheat from the number of sown seeds and seedlings was noted when the sowing rate was reduced from 7 to 4 million: without fertilizer 82.6–88.5 % in common wheat and 83.5–90.4 % of spelt. On a fertilized ground it amounted, respectively, to 84.3–90.5 and 86.5–92.3 %. Changes in nutritional background by introducing calculated doses of mineral fertilizers for all options with seeding rates on average for 2018–2019 yielded an increase in soft wheat by 0.94 tons of grain per hectare and by 0.61 tons of spelt. The highest conversion efficiency of fertilizers at a sowing rate of 6 million in common wheat was 8.1 kg of grain per 1 kg of a.a., for spelt at a sowing rate of 4 million the figure was 5.6 kg per 1 kg of a.a.

The aim of the research is allelic identifi cation of the genes Vrn A1, Vrn B1, Vrn B3, and Vrn D1 in 18 spring wheat samples and 3 lines obtained from winter-spring cross combinations with high carotenoid grain content for winter wheat breeding program. The content of carotenoid pigments in the grain ranged from 0.20 to 8.3 mg/100 g in the analyzed 143 samples of soft wheat. Samples of spring wheat were identifi ed for high content of carotenoids (more than 4.5 mg/100 g of flour): Volgouralskaya, Kinelskaya 61, Lutescens 540, Lutescens 598, Lutescens 575, Lutescens 516, Kinelskaya 2010, Omskaya 41. According to the studies, the presence of the Vrn-A1 allele established in 4 spring wheat samples (Sibiryachka 4, Frontana, Izolda, Dynastiya). The heterozygous state of the Vrn-A1 gene was determined for the Saratovskaya Zolotistaya variety. The presence of the allele Vrn-B1 was identifi ed in the samples Fora, Leningradka, Izolda, Saratovskaya Zolotistaya, Omskiy Tsirkon, Omskaya 41, Lutescens 540. For the samples Lutescens 516, L224-5 the heterozygous state of the locus Vrn-B1was determined. Analysis of the Vrn-B3 gene confi rmed the presence of the Vrn-B3 allele in all tested samples. Only variety Dynastiya carried a dominant allele. The Vrn-D1 gene was identifi ed in a recessive state in samples Fora, Sibiryachka 4, Novosibirskaya 22, Frontana, Leningradka, Kinelskaya 2010, Kinelskaya 61, Volgouralskaya, Omskaya 41, Lutescens 516, Lutescens 540, Lutescens 598, L224–5. In the variety Omskiy Tsircon gene Vrn-D1 was in a heterozygous state. The use of spring carriers of the trait – Samples Omskaya 41 and Lutescens 540, with one dominant gene Vrn-A1, and Lutescens 516, with the dominant allele of the gene Vrn-A1 and polymorphic in the Vrn B1 gene – were the most promising for the winter wheat breeding in the direction of increasing the carotenoids content in flour. Key words: bread wheat, variety, line, vernalization, carotenoids, genes Vrn A1, Vrn B1, Vrn B3, Vrn D1.
