The quality of rice kernel in early season cultivation is studied in comparison with that in usual or late season cultivation. In early season cultivation, rice kernels mature in haste and the accumulation of storage matter into the inner parts of kernel is abundant at early stage of maturation, therefore the arrangement of starch cells seems to be somewhat radial on the cross section of kernel. On the other hand, the weak kernels on panicle become frequently into milk-white kernels and chalky kernels on account of an unbalance between demand and supply of storage matter about 10 days after flowering, and some of the other kernels become into partially-chalky kernels and white-belly kernels owing to a tendency. to premature. On the kernels in early season cultivation number of aleurone cells and thickness of bran layer increase and embryos fall off more easily from kernels in process of cleaning, accordingly the cleaning-loss is relatively high as compared with that of the kernels in usual or late season cultivation.
