“…Glutenins consist of different subunits of high molecular weight (HMW‐GS, 80–140 kDa) and low molecular weight (LMW‐GS, 31–51 kDa), which form large aggregates joined by disulfide bonds. Gluten properties determine dough strength, which is greater when there are higher proportions of HMW‐GS than LMW‐GS polymers, although a high glutenin/gliadin ratio is also important in determining the functional proprieties of the gluten …”

“…Gluten properties determine dough strength, which is greater when there are higher proportions of HMW-GS than LMW-GS polymers, although a high glutenin/gliadin ratio is also important in determining the functional proprieties of the gluten. 3 Environmental factors and agronomic management play an important role in determining wheat quality characteristics. For example, temperature and precipitation during grain filling and nitrogen (N) availability are key factors in seed protein accumulation.…”

Variations in yield and gluten proteins in durum wheat varieties under late‐season foliar versus soil application of nitrogen fertilizer in a northern Mediterranean environment

et al. 2017

Late-season foliar N fertilization allows N fertilizer saving, potentially providing environmental benefits in the rainy climate of the northern Mediterranean area, and also leads to variety-dependent up-regulation of essential LMW-GS and gliadins. Variety choice is a key factor in obtaining high technological quality, although it is currently associated with modest grain yield. This study provides evidence of high quality in the specific high-yielding variety Biensur, suggesting its potential as a mono-varietal semolina for pasta production. © 2017 Society of Chemical Industry.

“…Quality is an important determinant in wheat breeding since the environment usually less affects its genetic background and sufficiently influences the commercial value of a cultivar (Varzakas et al, 2014). Wheat quality depends on the presence of certain alleles at loci, which are responsible for end product quality.…”

“…Wheat quality depends on the presence of certain alleles at loci, which are responsible for end product quality. Thus, if a certain cultivar possesses some specific allele combination at crucial loci, then it appears quite possible to exhibit valuable qualitative traits in terms of end product quality (Varzakas et al, 2014). However, production of a cultivar conferring improved quality also require a growing environment that favors expression of this genetic potential in order, for this, to lead to the eventual production of high-quality grain (Yong et al, 2004).…”

Grain quality is an essential component in wheat breeding programs since influences the commercial value of wheat. This study was conducted to determine the effects of genotype, season and sowing date on quality parameters of seventeen bread wheat commercial varieties and three advanced lines from Portuguese Wheat Breeding Program (Plant Breeding Station, Elvas, Portugal) under irrigated Mediterranean systems. Field experiments were conducted at two locations of Southeast Portugal (Elvas and Beja), during two growing seasons. At Elvas, results showed that environment (season) had highest contribution on variation of quality traits. At Beja experiments, the level of environment (season) influence decreased in relation to Elvas experiments: season was the most important factor to explain the variation of protein content and test weight, but for alveograph parameters (W and P/L ratio) it was found that genotype had higher influence. Sowing date was ever the most important factor to explain thousand kernel weight. The results confirmed that genetic potential is crucial to obtain high quality wheat but it is necessary a good environment to promote its expression.

“…This is attributed to the wide use of the 1BL.1RS translocation, and it is suggested that new sources of resistant genes must be obtained (Tang et al 2008). The presence of the 1BL.1RS wheat rye translocation can be detected with biochemical and molecular markers (Xynias et al 2007;Varzakas et al 2014). Seed storage proteins are the most common biochemical marker in wheat and an extended review on their application in wheat breeding was published by Xynias et al (2007).…”

The main motive of the present work was to detect and confirm the presence of the 1BL.1RS wheat-rye translocation in elite Hellenic bread wheat germplasm. For this, a molecular method was employed and seven Hellenic bread wheat cultivars (Acheloos, Acheron, Chios, Elisavet, Myconos, Orpheus, and Vergina) were studied. A rye population originated from Florina, and cultivar Kavkaz/Cgn, one of the donors of the 1BL.1RS translocation to bread wheat, were used as positive checks. The polymerase chain reaction was applied and two promoters for bread wheat gene alleles located on short arm of chromosome 1B (GLU-B3, GLI-B3) and one promoter for a rye gene (SEC I) located on short arm of chromosome 1R, were involved. It was demonstrated that cultivars Acheron, Elisavet and Orpheus do carry the 1BL.1RS translocation, whereas the rest of the varieties studied, they do not it. It was concluded that cultivars Acheron, Elisavet and Orpheus that carry the translocation, could be crossed to other elite genotypes lucking the translocation and produce new varieties possessing the advantages of the 1BL.1RS translocation. A special attention should be given to cultivar Acheron since this cultivar, despite the presence of the translocation carries favourable alleles in other gene loci affecting positively the quality of the produced bread.
