Variation in mineral micronutrient concentrations in grain of wheat lines of diverse origin

Effect of foliar application of Cu, Zn, and Mn on yield and quality indicators of winter wheat grain

“…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.…”

“…Luo et al (2001) conclude that the content of HMW and LMW fractions is genetically conditioned while Chope et al (2014) indicate the predominant role of N in forming relationships. According to Fuertes-Mendizábal et al (2010), an increase in the content of HMW glutenins (Table 6) Zhao et al (2009) Table 5. Protein fractions of gliadins and glutenins in winter wheat grain with foliar micronutrient application.…”

Nutritionally Enhanced Staple Food Crops

“…Highly significant and positive correlations (0.82-0.99) between seed P and phytate have been reported for common bean, pearl millet, and rice (Lolas and Markakis 1975;Stangoulis et al 2007;Selvi and Rajarathinam 2009), while a low but positive and significant association was found for seed phytate with Fe and Zn in common bean (Cichy et al 2009). Further, several studies in wheat and common bean revealed a moderate but positive and significant association of seed P with Fe (0.42-0.55) and Zn (0.46-0.63) (Gelin et al 2007;Peleg et al 2009;Zhao et al 2009;Zhang et al 2010), whereas in pearl millet these relationships were negative and highly significant (À0.70 to À0.74) (Arulselvi et al 2007). The implications of the above are that while it should be possible to breed for high seed-Fe and -Zn concentrations with reduced phytate concentration in pearl millet, this may not be possible in wheat or common bean.…”

“…However, it is either not associated with seedFe and -Zn concentrations in pearl millet or shows a low but significant negative association in wheat (Morgounov et al 2007;Peleg et al 2009;Zhao et al 2009) and positive association in common bean (Gelin et al 2007). A negative association may pose problems for breeding of seed mineral-dense cultivars with high seed yield per se.…”

Evaluation of the Mineral Content of Winter Wheat

“…[11][12][13] According to the data published on cultivars grown in different ecological conditions 14,15 there is a significant difference between the iron and zinc content of different bread flour genotypes but there is no such difference in the selenium content. The results of the Swedish experiments showed 16 that the decrease of air pollution resulted in a significant decline in lead and cadmium levels of wheat samples while as a consequence of the NKP fertilization treatment the copper and iron content declined.…”
