1) Azuki seeds were grouped into normal, small, malformed, corrupt, destroyed (due to injury of insects and crushed), wrinkled, unripe, and abostive grains. 2) The following characters such as specific gravity, weight, length, width, and thickness of the grains, and the correlations among them were investigated in order to establich the standard suitable for eliminating trash grain of Azuki seeds (Fig. I〜III. Table I). 3) Almost all of the corrupt grains and all of the unripe grains, also about harlf of the malformed grains and wrinkled grains were selected by the upperlimits of specific gravity of the unriped grains. About harlf of the destroyed grains and all of the small grains were selected by the upperlimits of weight of the small grains. In such way, the greater part of trash grains might be removed practically. 4) The Japanies Tomi (Winnowing fan) is best of all the farm tools for the selections of the Azuki seeds, and the most suitable wind velocity at the third exhaust (exhaust of the immature grain and dust) is 6.3 m/sec (Table II).
