In order to compare the pedigree method with the bulk-method, parallel experiments were conduced with the same hybrid poputation of rice. A number of elite-plants were seledted in F_2' and the rest of the population was cultivated in bulk by direct seeding during the follawing two years. In the second year (1947) , we had an opportunity to select coldresistant plants since the summer was so cool that m;ost of the cultivated rice varieties tended to steri-lity. A number of panicles were selected and the grains of ach were planted in 1948 in 40 plant-plots with no replication, in order to select among the F familie such which showed the least segregatian with regard to heading, plant height ,and other recognizable characters. Of these selected families, the number and weight of panicles and yield of grains per plant were recorded.
