Multiple element analyses were carried out to investigate variation in element concentrations in barley grains of 336 genotypes. Of 13 elements analyzed, Ba ranged from 0.2 to 8.9 mg kg−1, Ca from 186.4 to 977.5 mg kg−1, Cu from 1.5 to 9.8 mg kg−1, K from 353.2 to 7721.5 mg kg−1, Mg from 1049.8 to 2024.2 mg kg−1, Mn from 8.1 to 22.9 mg kg−1, Na from 55.9 to 627.9 mg kg−1, P from 2272.9 to 5428.8 mg kg−1, S from 880.7 to 1898.0 mg kg−1, Si from 19.1 to 663.2 mg kg−1, and Sr from 0.35 to 2.62 mg kg−1 in the barley grain. The least square means showed high Zn, Fe, Mg, P, and S concentration in AM-64 and AM-228 genotypes. The principal component analysis of element concentration showed four PCs explained 64.3% total variance. Strong positive correlations (p < 0.001) of Fe-Mn, Fe-S, S-Mn, Zn-P, Zn-Mg, Mg-P, Mg-Mn, and Ca-Sr were found. The identification barley genotypes that showed high elements concentration furnish valuable genetic resources for biofortification in future.
