“…In our study, a positive correlation occurred between grain Zn content and grain yield (r = 0.419), grain bulk density (r = 0.422), total gliadins (r = 0.413), γ gliadins (r = 0.499), total glutenins (r = 0.395), and HMW glutenins (r = 0.389). Oury et al (2006) and Zhao et al (2009) confirmed the negative relationship between Zn content and grain yield.…”

“…(iii) The increased grain yield and thousand-kernel weights of modern varieties as well as the changes in the ratio of bran to endosperm can also result in a relative lower micronutrient concentration in wheat grain. Oury et al (2006) found negative correlation between grain yield and Mg and Zn concentration. Additionally, negative correlation was found between the date of the variety release and the Zn and Fe concentration (Zhao et al 2009;Monasterio and Graham 2000).…”

Wheat-based food has great importance in human nutrition: in European countries they provide 20-30% of the daily calorie intake, and additionally, the wholemeal and healthy food becomes even more popular. Mineral content in grains is dependent on genetic and environmental factors (varieties, soil type, geographical location of the growing area, etc.), therefore, it is complicated to estimate how many percentage of the daily micronutrient requirements can be covered by wheat-based products. In this study, copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se) and zinc (Zn) contents of 13 commercial wheat flour products, and the white flour and wholemeal of 24 winter type bread wheat varieties were studied to estimate the nutritional value of these products. All investigated samples were produced in Hungary. Significant variation was revealed in the case of all mineral elements in the different brands of wheat flours. Generally, the white flour enriched with germ showed higher mineral contents than the average values of normal white flours. Furthermore, the wholemeal has higher Cu, Fe, Mn and Zn, but not higher Se contents than the white flours. Mo content was also higher in some brands of white flour than in wholemeal.The investigated winter wheat varieties showed significant differences in the case of Fe, Mn, Se and Zn contents, but none of the varieties showed outstandingly high micronutrient content. The milling process -as it was expected -reduces the concentrations of four elements (Fe 33%; Mn 88%; Zn 71%; Cu 44%); however, the Se and Mo concentrations were not affected significantly. Using the average micronutrient content in the wholemeal of varieties, the daily Mn and Fe requirement can be covered by the consumption of about 250 g wholemeal. Additionally, the daily Mo requirement could be met by the daily consumption of 140-190 g of commercial white or wholemeal flour.

“…timopheevii might be one of promising genetic resources for breeding iron-and zinc-fortified wheat via traditional cross and the grain yield might be not affected. Not only grain Fe and Zn concentrations displayed the very close positive correlation in a number of germplasm resources, but also they had some same characteristics like significant positive correlation with grain protein content, as well as negative correlation with the traits of glutenin content, plant height and grain number per m 2 (Oury et al 2006;Morgounov et al 2007). Hence, it was inferred that physiological and genetic factors involved in Zn and Fe deposition in the seeds are same or very similar, or the alleles for Zn and Fe deposition in the grain co-segregate or pleiotropic (Velu et al 2014).…”

Grains of 12 accessions of Triticum timopheevii (Zhuk.) Zhuk. ssp. timopheevii (AAGG, 2n = 4x = 28) and one bread wheat cultivar Chinese Spring (CS) and one durum wheat cultivar Langdon (LDN) grown across two years were analyzed for grain iron (Fe) and zinc (Zn) concentrations. All the 12 tested T. timopheevii ssp. timopheevii genotypes showed significantly higher concentration of grain Fe and Zn than CS and LDN. Aboundant genetic variability of both the Fe and Zn concentrations was observed among the T. timopheevii ssp. timopheevii accessions, averagely varied from 47.06 to 90.26 mg kg -1 and from 30.05 to 65.91 mg kg -1 , respectively. Their grain Fe and Zn concentrations between years exhibited a significantly positive correlation with the correlation coefficients r = 0.895 and r = 0.891, respectively, indicating the highly genetic stability. Flag leaf possessed twice or three times higher concentrations for both Fe and Zn than grain, and a significantly high positive correlation appeared between the two organs with r = 0.648 for Fe and r = 0.957 for Zn concentrations, respectively, suggesting flag leaves might be indirectly used for evaluating grain Zn and Fe contents. Significant correlations occurred between grain Fe and Zn concentrations, and between grain Zn concentration and the two agronomic traits of plant height and number of spikelets per spike. Both the concentrations were not related to seed size or weight as well as NAM-G1 gene, implying the higher grain Fe and Zn concentrations of T. timopheevii ssp. timopheevii species are not ascribed to concentration effects of seed and the genetic control of NAM-G1 gene. There might be some other biological factors impacting the grain's Zn and Fe concentrations. These results indicated T. timopheevii ssp. timopheevii species might be a promising genetic resource with high Fe and Zn concentrations for the biofortification of current wheat cultivars. Keywords IntroductionIt has been reported that micronutrient malnutrition, particularly deficiencies in Fe and Zn, afflicts a very large proportion of the world's people. The World Health Organization estimated that more than 2 billion people have deficiencies in Zn and Fe, resulting in overall poor health, anemia, increased morbidity and mortality rates, and low worker productivity (Hotz and Brown 2004;Welch and Graham 2004;Bouis 2007;Cakmak 2008;Salim-Ur-Rehman et al. 2010). Currently, the phenomena which are termed "hidden hunger" (FAO 2002), generally occur in developing countries, where most people rely on cereal grain as their staple food.Bread wheat (Triticum aestivum L.) is one of the most important staple food crops, providing 28% of world's edible dry matter (Cakmak 2008). So, the composition and nutritional quality of wheat grain have a significant impact on human health and wellbeing worldwide (Chatzav et al. 2010;Wang et al. 2011). In the past, a great effort has been made for improving wheat grain yield and resistance to leaf diseases (He et al. 2004). However, little attention was given to microm...
