The object of this experiment is to determine the suitable physiological age of potato seed tubers for spring culture in relation to several varieties. The results obtained may be summarized as follows: 1) From the standpoint of the yield of primes (above 100gr. in weight per tuber) per 10 are, five commercial Varieties used in this study were grouped into types of summer-grown seed tubers and of fall-grown seed tubers; in the former about 6 months of age and in the latter 3 or 4 months of age are suitable for spring culture respectively. 2) Wheeler and Irish Cobbler, which has a long rest period, belong to a type of summer-grown seed tubers, while Norin No. 1, which is late in maturing in spite of its a short rest period, is also a type of summer-grown seed tubers. 3) Ojiro and Unzen are of type of fall-grown seed tubers. These varieties have short rest. period and early maturity. 4) From the results of these experiments, it is note worthy that the fall grown seed tubers of Unzen, Ojiro and Wheeler become of possible use for spring culture of potato.
