“…Correlation analyses further detected the significantly positive correlation between the concentrations of grain Fe and Zn in the T. timopheevii ssp. timopheevii accessions (Table 2), which agreed with previous studies of a number of germplasm from wild and modern wheat and spelt wheat (Morgounov et al 2007;Chatzav et al 2010;GomezBecerra et al 2010a, b). This illustrated the tested T. timopheevii ssp.…”

“…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).…”

“…timopheevii materials were genetically stable for controlling grain Fe and Zn concentrations. Morgounov et al (2007) reported that there is a significant negative correlation between the concentrations of grain Fe and Zn and the grain yield in modern cultivars. But, there seems to be no correlation between thousand-kernel weight (TKW) and grain Zn content in adapted wheat lines (Velu et al 2012).…”

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...

“…In yet another issue of correlations and micronutrient versus macronutrient concentrations, seed yield is significantly and positively associated with seed weight in cereals and legumes (Upadhyaya et al 2002;Garcıa del Moral et al 2003;Upadhyaya 2003;Maman et al 2004;Morgounov et al 2007). 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).…”

Human malnutrition associated with zinc (Zn) deficiency is a growing problem in many areas. This study was conducted to assess wheat (Triticum aestivum L.) genotypic variation of grain Zn concentration, grain germination, and grain yield in response to foliar application of Zn. Twenty-four wheat genotypes, including several recombinant inbred lines (RILs) and commercial cultivars, were assessed in two separate experiments; one experiment sprayed with ZnSO 4 ⋅7H 2 O dissolved in water at wheat heading growth stage and one without applying Zn foliar treatment. The range for grain (25.1-63.1) and endosperm (1.2-61.6 mg kg −1 ) Zn concentrations were different between the two Zn treatments. Significant (p = .05) genotype × Zn treatment interactions showed that some genotypes were more responsive to Zn applications than others. The application of Zn increased the Zn concentration in the endosperm in 18 out of the 24 genotypes. For grain, Zn application increased the concentration in the grain in 21 out of the 24 genotypes. Grain yield and germination were increased in the Zn treated cultivars compared with non-treated. In conclusion, foliar application of Zn improved traits in wheat, and identified genetic variation lays the foundation for genotype selection with respect to higher Zn concentration.Abbreviations: CCA, canonical correlation analysis; CIMMYT, international maize and wheat improvement center; DTZ, diphenyl-thiocarbazone; GCV, genotypic coefficients of variations; GE, germination energy; GS, germination speed; GV, germination value; MTG, mean time of germination; PCA, principal component analysis; PCV, phenotypic coefficients of variations; RCBD, randomized complete block design; RIL, recombinant inbred line; TPN, total pixel number.
