The tendencies of rice breeding and seeds multiplication in Japan are becoming more intentionally and rationally. The genetic stocks of rice, therefore, are demanded to be more uniform from the viewpoint of gene constitution even in regard to the physiological and ecological characters. In any case of supplyingy the seeds to breeders, these demands for above characters could only be secured by maintaining the bulk seeds of uniform under dry and cold conditior*s. With the advances in the techniques of seeds storage and its practical use on the permanent maintenance of genetic stocks of rice, the authors have hitherto been worked, there seems to be of great significant to apply them to improve the systems of maintenance of breeder's seeds and the procedure of rice breeding as well as the maintenance of genetic stocks. The practical procedures of improved systems are shown with special contrast with present bnes as in Figures 1-4.
