he aim of this study was to compare mineral and arabinoxylan contents 24 in whole meal and white wheat flour, as well as delineate the influence of genotype and climatic conditions on the variation of these components. Eleven commercial bread wheat cultivars from Argentina obtained in two consecutive harvests were analyzed. Protein, arabinoxylan, mineral concentration and localization were determined. For T-AX variation, year was the main factor accounting for the variability found both in whole meal and in white flour, while WE-AX content was more influenced by genotype on both fractions. There was an average reduction of 56% of T-AX after milling. Mineral content was significantly influenced by genotype and harvest years. Milling significantly reduced the concentration of all the elements (p< 0.05). Fe and Zn concentrations in white flour were highly variable. Milling loss had a wide variation from 10 to 74% for Fe, and from 19 to 68 % for Zn. Genotypes with lower T-AX, Fe and Zn mi
