This series of experiments was carried out with respect to 38 leading varieties of sesame as material, which were collecte in eight countries including Japan, to find the change in germination conditions, varietial differences, and the relation to several of their characters, seeding them at the depths of 0.5,1.5,3,5 and 7 cm each. The results of the experiments are as follows : 1) The deepest limit of seeding which permitted germination was 5 cm. African varieties attained the best germination both in shallow and deep seeding. 2) Israel varieties produced no better results than the other varieties in shallow seeding, but they showed germination next best to the African varieties, in deep seeding. 3) Generally, the African varieties required the least average number of days for germination, with American and Korean varieties following. 4) The covariance of the welght of the 1000 seeds and germination coefficient in 0.5 cm seeding, from the view point of all varieties, had (-) correlation, and the heavier the seeds the lower germination coefficient they showed, and within groups they also showed the same (-) correlation. On the other hand in deep seeding (-) correlation was seen concerning all varieties and also with groups. The heavier the seeds the higher the germination coefficient. 5) The covariance of the days from seeding to flowering and the germination coefficient, there was no correlation whatever in (0.5 cm) shallow seeding. But in deep seeding (5 cm) such late varieties as African and Indonesian showed higher germination coefficients, while such early varieties as Korean and such medium varieties as American showed lower germination coefficients. 6) The covariance of the oil contents and the germination coefficient : the more oil the seeds contained the worse germination followed in shallow seeding ; while in deep seeding comparatively better results were recognized. 7) When germination in the germinater was compared with that in the field, the germinater and the field gave the same results in shallow seeding. In the case of the Israel and Indonesian varieties, those varieties that showed the higher germination coefficient in the field showed the lower germination coefficient in germinater. The varieties that showed the higher germination coefficient when sown at the depth of 5cm showed the lower germination coefficient in the germinater. African and Chinese varieties showed the same germination tendency either in the germinater or in the field.
