Distribution of fresh, dry, weight and percentage of the latter against the former of tuberous root in F<SUB>1</SUB> plants of sweet potato were investigated in conformity with the data of the seedling selection experiments in Chiba Experiment Farm of Kanto-Tusan Agricultural Experiment Station and Kagoshima Experiment Farm of Kyusyu Agricultural Experiment Station, in the aim of contribution to the selection of the prospective cross combination. Consequently the most productivities were shown in the frequent medium percentage of the dry matter (30∼38%). Accordingly when the miximum of calorie products per area are desired, we may expect the medium percentage more than the high percentage of dry matter. Therefore it will be advisable to make use of the productive varieties in case of the selection of cross combination. As there are very high correlations between fresh and dry yield, we may mark F<SUB>1</SUB> individuals in respect of fresh weight primarily and then in point of dry matter percentage secondarily.
