We grew 12 modern winter wheat varieties in semi-arid conditions and alkaline soils, in two consecutive years of contrasting water availability, and at three rates of N-fertilization: 64, 104, and 130 Kg N/ha. We found that the genotype was the main driver of [Ca], [K], [Mg], and [S] in wheat grain, while the environmental conditions were more relevant for [Fe] and [Zn]. The nitrogen fertilization rate had little effect on yield or mineral concentration in the grain. The thousand-grain weight correlated negatively with the mineral concentration in the grain, revealing the importance of grain shape. CH-Nara grains were highly nutritious making this variety a potential source of germplasm. The knowledge gained from this study will guide future breeding and agronomic practices and guarantee food safety in the region in the advent of climate change.
