The results obtained from the study of transparency of glutinous hulled grains and the relation of the transparency to the other characters of grains for bred 12 lines of upland rice at the Odate Agricultural Improvement Experiment Station of Ministry of Agriculture and Forestry were as follows (See Table 1〜4). 1. Each individual of the lines bore the semi-transparent grains as well as the opaque grains, and the rate of coexistence of the opaque and semi-transparent grains in an ear varied with the lines. 2. The weight of opaque grains for 8 lines were heavier than that of semi-transparent grains, but the weight of opaque grains for the other 4 lines were equal to that of semi-transparent grains. On the other hand any relation could not be found between the rate of coexistence of two sorts of grains for each line and the weight difference of two sorts of grains consisting in each line. 3. The length and width of the opaque grains were bigger than that of the semi-transparent grains. But the thickness and the length, the thickness factor of the opaque grains were smaller than those of the semi-transparent grains. While the length, the width factor of two sorts of grains did not show any relation to the above mentioned transparency. 4. The specific gravity of the opaque grains was greater than that of the semi-transparent grains and the specific gravity varied with me lines. 5. The opaque grains had an inclination to be dyed deeply by the iodine potassium iodide solution as compared with the semi-transparent grains, but two sorts of grains of Tohoku-mochi No.1 had an equal degree of dyeing. Generally speaking, the ability to be dyed varied slightly with the lines.
