“…Tańska et al [52] reported that variation in grain color of wheat was reflected by changes in its chemical composition but not the environment which is in partial agreement with the results of our study. In addition, the accumulation of carotenoids and anthocyanins pigments in wheat grain accounted for the large variation in its grain color [52][53][54][55] and may have played a role in the grain color differences for the single variety of teff sampled across multiple locations in our study. Overall, the average of 63.5% of the variation in grain color can be attributed to the variation in the soil physicochemical properties that influenced several parameters that were correlated with grain color in this study (Table 5).…”

Teff is the only cultivated cereal crop from the genus Eragrostis and it is the major staple food of Ethiopians. In Ethiopia, the quality of teff and its market price are primarily determined by its grain color. The objective of this study was to evaluate the effects of soil physicochemical characteristics across multiple locations in the two main teff growing regions of Amhara and Oromia states in Ethiopia on teff grain color and nutritional quality of a single variety. Grain and soil samples were collected from 24 field sites cultivated with the popular teff variety ‘Quncho’ (DZ-Cr-387/RIL-355). The teff grain samples collected from the 24 locations were evaluated for grain color, proximate composition, amino acid composition, and grain mineral concentration and the soil samples were analyzed for their physicochemical properties. Sample location means were considered different p < 0.05. Teff grain color indices of hue (H), saturation (S), and brightness (V), grain proximate composition, amino acid composition, and mineral concentration differed among locations (p < 0.05). There were significant negative correlations between grain S color value and soil pH, SOC, Ca, Mg, S, and Na. Soils with greater pH, SOC, Ca, Mg, and S generally had lower S values and thus, whiter color teff grains. There were considerable variations in the measured parameters for soil and teff grain physicochemical properties. The results indicated an opportunity for management interventions necessary to obtain uniformity in grain color and chemical composition for the same variety of teff grown in the two major regions in Ethiopia.

“…bessarabicum, were used as donors of the Ba genes. These genes are usually transferred into the wheat genome as additional chromosomes or as alien chromosomes substituting for wheat chromosomes in the homologous group 4 [16,22,[47][48][49], whereas there are great difficulties in obtaining stable wheat recombinant chromosomes carrying the Ba gene. Recently, based on the line Blue58 having chromosome substitution 4Th(4D), a set of blue-grained translocation lines with Th.…”

Marker-Assisted Development of a Blue-Grained Substitution Line Carrying the Thinopyrum ponticum Chromosome 4Th(4D) in the Spring Bread Wheat Saratovskaya 29 Background

There is growing interest in cereals with anthocyanins in grain as a source of natural biologically active compounds beneficial for human health. In bread wheat, anthocyanins accumulate in the pericarp, under control of Pp genes, and in the aleurone layer, under control of Ba. Breeding anthocyanin-rich wheat cultivars is possible through the transfer of genes from genetic stocks to the desired cultivars. A blue-grained substitution line, s:S294Th(4D) (BC7 progeny), of the bread wheat cultivar Saratovskaya 29 (S29) carrying the Thinopyrum ponticum (Podp.) chromosome 4Th was developed. The 4Th/4D substitution was confirmed with chromosome C-banding and multicolor FISH, as well as by microsatellite analysis. Total anthocyanin content in the bran fraction of the new blue-grained line was 475.7 μg/g compared to 355.6 μg/g of the control purple-grained near-isogenic line, i:S29Pp-A1Pp-D1Pp3P, and a total absence in S29. Although the developed line carries entire chromosome substitution, its 1000 grains weight, milling parameters, and dough physical properties did not differ or decreased slightly comparison to S29. These results support that the developed substitution line can be of interest in breeding programs to increase the anthocyanin production in commercial varieties.

“…Anthocyanin biofortified wheat has attracted the attention of many researchers across the world, but the developed lines exhibit low yield due to linkage drag [174]. In India, Garg et al [163] developed coloured wheat lines viz. blue, purple and black, with reasonable yield potential and regional adaptation.…”

Wheat is the essential constituent of cereal-based diets and one of the most significant sources of calories. However, there is an inherently low bioavailability of proteins, mineral, and vitamins in modern wheat grains. Biofortification has earned recognition as an outstanding approach, at the same time as a cure for world hunger. The developments in the identifications of quantitative trait loci (QTL) analysis and understanding of the physiological and molecular basis of QTLs controlling the biofortification traits in wheat has revealed new horizons for the improvement of modern wheat varieties. Within this review, we have compiled the information from the studies carried out in wheat using QTL mapping methodologies that is among the best methods for biofortification traits. We hope this review will serve as an essential reference for the QTLs identified for the several important biofortification traits in wheat.that could contribute to underexploited wild relatives [25,26]. The different steps involved in the development of biofortification wheat with the aid of marker-assisted breeding are presented in Figure1. Figure 1.Representation of different strategies for biofortification of the wheat, especially explaining different steps of marker-assisted breeding.Conventional breeding methods are easy to operate with qualitative traits. These traits depend on a single gene whereas traits like yield are quantitative and therefore are impacted by several genes [27,28,29]. There are several techniques for mapping quantitative trait loci (QTL) in an experimental cross [30]. The molecular basis of QTLs is challenging to dissect, even for model plants like Arabidopsis and rice, because of the problems in precisely narrowing intervals to single genes [31]. Experimental design, type of plant population analysed and the level of polymorphisms between parental genomes also affect the predictions of QTLs. Statistical methods to determine quantitative trait loci (QTL) require numerous molecular markers with high-resolution genetic maps [32,33]. This approach is also related to genomics methods which are geared toward the dissection of complex phenotypes [34].Genomic resources of wheat have provided important support for functional genomics and conservation biology (by conserving the important landraces) [35,36]. The wheat genome is complex to interpret simply because of broadly dispersed repetitive sequences, heterozygosity, and polyploidy [37,38]. Nevertheless, the developments in sequencing methodologies, decreased sequencing price, together with the advancements in the computational resources have permitted the spread of these resources [39,40]. Besides, the comparative genomics among plant species is demonstrating to be an efficient method for the identification of novel genes regarding the biofortification of modern wheat [41]. Therefore, in this review, we have compiled the QTLs Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted:
