This study was carried out to characterize the color of noodle sheet made from Korean wheat cultivars, which were then evaluated on grain and flour properties, in order to enhance the breeding-line selection for noodle wheat. In particular, a rapid method was applied to investigate the effects of iron (Fe) contents on the lightness of noodle sheet for the selection of breeding-lines with high Fe contents. Wheat flour lightness of Korean wheat cultivars had a negative correlation with ash (r = -0.634, P<0.01), protein (r = -0.635, P<0.01) and total polyphenols (r = -0.493, P<0.05). The noodle sheet color showed a positive correlation with lightness, but a negative correlation with test weight, 1000 kernels weight, PPO activity and total polyphenol contents. Also, upon the wheat flour properties, the ash, protein and total polyphenol contents had a negative correlation with the lightness of noodle sheet, and this relation varied depending on the year and cultivars. The Fe content had a negative relation with the color of wheat flour and the lightness of noodle sheet, and the potassium hexacyanoferrate(II) trihydrate (PHT) test resulted in blue color. There was no correlation between Fe contents and the color of grains with PHT treatment, but after grounding the whole grains, a negative correlation was found between Fe contents and redness (r = -0.665, P<0.001) and yellowness (r = -0.658, P<0.001) of whole wheat flour with PHT treatment. On the other hand, the lightness of wheat flour with PHT treatment showed a negative relation with Fe content.
