“…The QTLs that mapped to chromosomes 7A (Mares and Campbell 2001;Patil et al 2008;Zhang et al , 2009Howitt et al 2009;Blanco et al 2011) and 7B (Kuchel et al 2006;Pozniak et al 2007; have been shown to explain in many cases the highest percentages of observed phenotypic variability (>50%) (Parker et al 1998;Elouafi et al 2001). Recent findings have shown that as well as the QTLs mapped at the telomeric region of the long arms of these chromosomes, there are other QTLs that have minor effects on colour traits on both arms of chromosomes 7A (Singh et al 2009;Blanco et al 2011;Roncallo et al 2012) and 7B Blanco et al 2011;Roncallo et al 2012).…”

“…Significant marker-trait associations for YPC have been detected on all of the chromosomes by linkage mapping (Parker et al 1998;Hessler et al 2002;Pozniak et al 2007;Patil et al 2008;Zhang et al , 2009Howitt et al 2009;Blanco et al 2011;Roncallo et al 2012) and by association mapping (Reimer et al 2008).…”

“…Almost 50 different alleles have been identified at the Psy-A1 and Psy-B1 loci in different species of wheat (He et al 2008(He et al , 2009aHowitt et al 2009;Singh et al 2009;Wang et al 2009;Crawford et al 2011;Ravel et al 2013) (Table 1). The genes coding for PSY were mapped to the chromosome 7 groups by Pozniak et al (2007); in particular, the Psy-B1 locus co-segregated with a QTL on chromosome 7B, which demonstrated an association between the position of this gene and part of the phenotypic variation for endosperm colour (Pozniak et al 2007;Roncallo et al 2012). Similarly, Psy-A1, located on chromosome 7A, showed a co-dominant marker based on polymorphisms between two Psy-A1 haplotypes that explained 20-28% of the phenotypic variance for YPC across three environments (He et al 2008).…”

The colours of durum wheat: a review

Abstract. Pigments are essential to the life of all living organisms. Animals and plants have been the subjects of basic and applied research with the aim of determining the basis of the accumulation and physiological roles of pigments. In crop species, the edible organs show large variations in colour. In durum wheat grain, which is a staple food for humans, the colour is mainly due to two natural classes of pigment: carotenoids and anthocyanins. The carotenoids provide the yellow pigmentation of the durum wheat endosperm, and consequently of the semolina, which has important implications for the marketing of end products based on durum wheat. Anthocyanins accumulate in the aleurone or pericarp of durum wheat and provide the blue, purple and red colours of the grain. Both the carotenoids and the anthocyanins are known to provide benefits for human health, in terms of decreased risks of certain diseases. Therefore, accumulation of these pigments in the grain represents an important trait in breeding programs aimed at improving the nutritional value of durum wheat grain and its end products. This review focuses on the biochemical and genetic bases of pigment accumulation in durum wheat grain, and on the breeding strategies aimed at modifying grain colour.

“…Major QTL associated with the color of flour have been found on all chromosome arms using recombinant inbred lines, DH populations and the genetic resources of common wheat (Triticum aestivum L.) (Mares & Campbell, 2001;Kuchel et al, 2006;Zhang et al, 2009aZhang et al, , 2009bSadeque & Turner, 2010a;Bordes et al, 2011;Li et al, 2011;Tsilo et al, 2011;Roncallo et al, 2012;Zhao et al, 2013). The QTL for yellow pigments, polyphenol oxidase and carotenoid genes were also found to be associated with the flour and noodle color (Marles & Campbell, 2001;Raman et al, 2007;He et al, 2008;Zhang et al, 2009b;Sadeque & Turner, 2010b;Crawford et al, 2011;Martin et al, 2011;Crawford & Francki, 2013a, 2013b.…”

This study was conducted for identification of the quantitative trait loci (QTL) associated with the color of flour and noodle dough sheets for the production of white salted noodles by analysis of a doubled haploid population from a cross between Korean wheat cultivars carrying different color values for the flour and noodle dough sheets. The DH population was evaluated in replicated field trials in 2011 and 2012 in upland conditions in Iksan, Korea. The color differences were measured as CIE-LAB L, a and b values. Xgwm190 located on chromosome 5D explained 13.3%-22.8% of the phenotypic variation in the color of flour over the average of two years. Xgwm190 also explained 11.8% and 24.1% of the phenotypic variation for the L and b values of the noodle dough sheets for the average of two years, respectively. Xbarc81 and Xgwm133 accounted for 7.9% and 9.8% of the phenotypic variation in the b value of flour produced in 2012 and the noodle dough sheets from flour produced in 2011, respectively. The putative marker for flour and noodle dough sheet color, Xgwm190, was applied to validate the relationship between genotypes of 24 Korean wheat cultivars. Fourteen of the Korean wheat cultivars contained genotype a, which represented homozygous to Keumkang at Xgwm190, showed lower L values of the flour and noodle dough sheets (91.6 and 83.5, respectively) than genotype b (93.6 and 85.1, respectively), which represented homozygous to Olgeuru at Xgwm190. Xgwm190 could be used for the selection of wheat lines with bright color in Korean wheat breeding programs.

“…The availability of a large number of genetic resources is essential for this procedure. To date, significant progress in identifying QTLs conferring yield components, grain qualities, and disease resistance in durum wheat varieties has been achieved (Zhang et al, 2008;Simons et al, 2011;Roncallo et al, 2012). The wild germplasm of durum wheat, which represents a rich potential source of useful under-exploited genes, has also been used as a resource to provide genes of interest.…”

ABSTRACT. Durum wheat (Triticum turgidum durum; 2n = 4x = 28; genome AABB) has long been an important food resource for human diets. The projected increase of the world's population to 9.1 billion by 2050 has highlighted the importance and urgency for improving the yield and quality performance of durum wheat. A backcrossed population, which was derived from the durum wheat variety 'Bellaroi' (recurrent parent) and the hexaploid genotype 'CSCR6' (donor parent), was used to investigate the feasibility of improving yield-and quality-related traits of durum wheat by introgressing chromosome fragments from hexaploid wheat. The population means for grain protein content, gluten content, spike length, and spikelet number were improved compared with those of the recurrent parent 'Bellaroi'. A small proportion of the backcross population lines showed significant improvements in spike length and spikelet number compared with the recurrent parent Improving yield and quality traits of durum wheat 'Bellaroi'. Some loci with significant effects for plant height, spike length, spikelet number, and thousand-grain weight were identified. Several of these loci affected more than one trait. These results showed that the introgression of chromosome fragments from 'CSCR6' into the durum genetic background could be an effective method for improving yield and quality traits of durum wheat. In addition, the loci showing significant effects on desired traits in this study could be fine mapped using an F 2 population obtained by backcrossing the lines that carry the positive allele(s) with the recurrent parent.
