Germinating power of rice seeds with special reference to the location on the flower panicle was compared under various conditions. Excepting the second and the third spikelets on secondary branch, the comparable spikelets from different primary branches on the panicle exhibited almost similar germinating power. However, there were distinct differences between the spikelets from different location on a primary branch, namely, such vigorous spikelets as what would mature earlier were superior to the weaker spikelets in both the germinating percentage and the rapidity of germination, and the second and the third spikelets on the secondary branches were remarkably inferior to the others. These differences were more marked under unfaborable conditions.
