Protein, Mg, P, S, Cl, K, Ca, Mn, Fe, Cu, and Zn concentrations were determined in wheat flour, bran, and grain from 27 cultivars in the 12th International Winter Wheat Performance Nursery grown at six locations. Variations in mineral and protein concentration of flour, bran, and grain were demonstrated and could be attributed to differences in growing locations, cultivars, and their interaction. Variations in environment and genotype had a somewhat different influence on flour and bran composition. Mineral concentrations in bran were more strongly influenced by environmental conditions than were flour mineral concentrations. Concentrations of P and Mn in flour were influenced more by genotype than environment. Whole grain composition tended to reflect an average of the responses of flour and bran. The interaction of genotype and environments also contributed to mineral and protein variability. Protein content of grain had a positive influence on concentrations of all minerals except Cl and K.
