Thirty Tohoku and 30 foreign wheat cultivars were grown under the same cultivation condition and were analyzed about milling quality. Wheat cultivars were classified into the small group and the large group based on the specific surface area (SSA). The small group was big particle size of A flour and high milling rate, and the other group was small and low. Namely, the small group is considered to be hard wheat and the large group is considered to be soft wheat. The classification of cultivars based on the A flour rate coincides with the classification based on SSA. In the hard wheats, the higher regression coefficient of flour yield rate to SSA was higher than in the soft wheats. It is shown that the effect of selection by SSA in milling characteristics was higher in the soft wheats than that in the hard wheats. The hard wheats differed with the soft wheats in the milling characteristics. It is necessary that the examination of milling characteristics of wheat cultivar has to be conducted in the same hardness group
