“…As scientifically well proven, plant species (Moraghan, 1984) and cultivars within a species, particularly in wheat (Cakmak et al, 1996b(Cakmak et al, , 1998Graham et al, 1992) significantly differ in their ability to take Zn up from soils or to utilize it internally. As in wheat, there are also sizeable genotypic differences among the barley cultivars concerning Zn efficiency (Graham et al, 1992;Yilmaz et al, 1996;Cakmak et al, 1998;Sadeghzadeh et al, 2016).…”

To some extent, differential zinc (Zn) efficiency of cereals, particularly differences between species may be attributed to phytosiderophores (PSs) release and inorganic Zn (Zn 2+) uptake; however, the discrepancies within a given species are still under discussion. Moreover, studies on the explanations of differential Zn efficiencies of barleys are limited. That is why using two barley (Hordeum vulgare L.) cultivars (Zn-efficient, Tarm-92 and-inefficient, Hamidiye-79), two short-term uptake experiments were designed with two forms of Zn, free Zn (Zn 2+) or PS chelated Zn (Zn-PS) labelled with radioactive Zn (65 Zn) in nutrient solution culture. Similar to earlier studies, the Zn uptake by roots and its translocation to shoots of barley supplied as either free (Zn 2+) or chelated (Zn-PS) was induced under Zn deficiency. Although according to results of previous works, a close relationship between Zn 2+ uptake of roots and Zn efficiencies of the same barley cultivars might have existed, the outcomes of the present research showed the opposite. Neither the uptake of Zn 2+ and Zn-PS from roots nor their translocation to shoot had any compatible connection with the Zn efficiencies of barley cultivars. So the reason for differential Zn efficiency within a given cereal species remained unclear including barley as well.

There is a little information regarding the chromosomal regions conferring seed zinc accumulation in barley. With the aim of QTL mapping of Zn concentration and content, 121 barley genotypes (including local landraces, released cultivars, gene bank germplasm) were screened under field conditions. The trial was conducted in square latice in 2015-2017 cropping seasons at dryland agricultural research institute (DARI) in Maragheh. To construct genetic linkage map, 149 SSR markers were applied. Based on ANOVA, there was a great genotypic variation for seed Zn concentration and content among the genotypes, which approves the excessive diversity of genotypes. Five QTLs located on 2H, 3H, 4H and 5H were associated with seed Zn concentration, and could explain 81% of total phenotypic variation. Marker BMAG0720 had the highest (25%) phenotypic variation. This marker could also explain 23% of total variation for seed Zn content. Moreover, 5 genomic regions on 2H, 3H and and 4H were associated with seed Zn content. In conclusion, the identification of these major QTLs would provide an important starting point for marker assisted selection (MAS) that may contribute to the improvement of barley productivity and nutritional quality.
