“…As a result of the studies, lines with the best expression for these traits were identified: 1762/17, 1401/19, 1361/19, 1343/19, 1420/19, 1120/19 and 1638/19 Figure 3. Varieties according to flour strength, W Valorimetric assessment is a single generalizing indicator of the physical properties of the dough and key elements of the quality of final wheat products, determined using a farinograph [15]. The following requirements are imposed on varieties of "strong" quality for this trait, at least 70-85 units of the valorimeter.…”

Wheat bread rightfully belongs to the greatest inventions of mankind. The concept of wheat quality is very capacious and includes a wide range of characteristics: physical, chemical, rheological and consumer, which are in complex relationships with each other. The main purpose of soft wheat is the manufacture of bakery products. In this regard, the actual task of science is the creation and introduction into production of new varieties with high baking properties. The purpose of the research is to study the variability and relationships of quality traits; identification of the best varieties for use in the breeding process. It was found that the most strongly varying features were the specific work of deformation of the dough (11.7%) and the coefficient of the ratio of dough elasticity to extensibility (23.5%). The results of a correlation analysis on the conjugation of the characteristics of the quality of grain, flour and baking properties are presented. The quality of bread significantly depended on the volumetric yield of bread (r=0.9118) and the specific work of dough deformation (r=0.5119). A significant positive, strong relationship was found between the content of protein and gluten in the grain (r=0.8471). New varieties and lines of winter soft wheat of intensive type, distinguished by a complex of studied traits: the new variety Privolye, lines 1518/18 and 1401/19, are recommended to be used in the breeding process aimed at improving the quality of winter soft wheat grain.

“…In this study, association analysis of mixograph-related traits was performed using high-density SNP arrays. Barakat et al [ 2 ] reported 108 loci for farinograph- and mixograph-related traits on all 21 wheat chromosomes in two double haploid (DH) populations. Three loci on chromosomes 1B, 2B and 3B overlapped present loci on chromosomes 1B (13.5–14.5 Mb) for MTxW, 2B (738.2–752.8 Mb) for MPT and 3B (561.0–579.3 Mb) for MPW.…”

“…Dough rheological properties with significant effects on end-use products can be evaluated by mixograph [ 1 , 2 ]. Midline peak time (MPT), midline 8 min band width (MTxW), mid-line peak width (MPW) and midline peak value (MPV) are related to processing quality [ 3 , 4 ].…”

“…Dough strength is a typical quantitative trait controlled by multiple minor genes. A number of studies have been conducted which focus on identifying QTLs for mixographs and a series of QTLs for mixograph-related traits [ 2 , 13 , 14 , 15 , 16 , 17 ] were reported mainly by bi-parental linkage mapping.

Processing quality is an important economic wheat trait. The marker-assisted selection (MAS) method plays a vital role in accelerating genetic improvement of processing quality. In the present study, processing quality in a panel of 165 cultivars grown in four environments was evaluated by mixograph. An association mapping analysis using 90 K and 660 K single nucleotide polymorphism (SNP) arrays identified 24 loci in chromosomes 1A, 1B (4), 1D, 2A, 2B (2), 3A, 3B, 3D (2), 4A (3), 4B, 5D (2), 6A, 7B (2) and 7D (2), explaining 10.2–42.5% of the phenotypic variances. Totally, 15 loci were stably detected in two or more environments. Nine loci coincided with known genes or QTL, whereas the other fifteen were novel loci. Seven candidate genes encoded 3-ketoacyl-CoA synthase, lipoxygenase, pyridoxal phosphate-dependent decarboxylase, sucrose synthase 3 and a plant lipid transfer protein/Par allergen. SNPs significantly associated with processing quality and accessions with more favorable alleles can be used for marker-assisted selection.

Heat stress substantially reduces the yield potential of wheat (Triticum aestivum L.), one of the most widely cultivated staple crops, and greatly threatens global food security in the context of global warming. Few studies have explored the heat stress tolerance (HST)-related genetic resources in wheat, however. Here, we identified and fine-mapped a wheat HST locus, TaHST2, which is indispensable for HST in both the vegetative and reproductive stages of the wheat life cycle. The genetic materials used in this study produced different grain morphologies under HS, based on which we mapped TaHST2 to a 485-kbp interval on chromosome arm 4DS. Under HS, TaHST2 confers a superior conversion rate from soluble sugars to starch in wheat grains, resulting in faster grain filling and a higher yield potential. A further exploration of genetic resources indicated that TaHST2 underwent a strong artificial selection during wheat domestication, suggesting it is an essential locus for basal HST in wheat. Our findings provide deeper insights into the genetic basis of wheat HST and might be useful for global efforts to breed HST cultivars.
