From these studies investigated on positions in panicle of ventral white, basal white, milky white like white core and milky white kernels, we considered on relations between shapes of white opaque parts and positions in panicle of these kernels. Based above consideration, we intend to make clear up the mechanisms of development of these kernels. Results are summarized as follows; 1) Milky white kernels developed at inferior positions in panicle as in Figure 1, and shapes are shown in Figure 2 to 13. White opaque parts of milky white kernels have many different shapes as shown in these figures. 2) Ventral white kernels developed at superior position in panicle as in Figure 1, and shapes are shown in Figure 14 and Figure 15. 3) Milky white like white core kernels developed in high prcentages in the second and the third grains of secondary branch of middle parts in panicle as in Figure 1, and shapes are shown in Figure 16 and Figure 17. 4) Basal white kernels developed in high percentages in the second grain of upper branches in panicle as in Figure 1, and shapes are shown in Figure 18 and Figure 19. 5) We make diagram of developmental process of superior medium and inferior spikelet as Figure 20. This figure is made by the consideration that inferior spikelets develop very slowly and need long days for full ripening. As shown in Figure 20, the most rapidly development time of superior spikelet corresponds to the early development time of medium spikelet (about several days after flowering). As same as above mentioned, the most rapidly development time of medium spikelet corresponds to the middle development time of inferior spikelet (about twenty days after flowering).
