A possible vaiue of winter-grown Irish Cobbler tubers of 4.0 months of age as the seed for the fall culture, was examined. The kinds of the seed tubers used in the experiment were the winter-grown seed tubers of 4.0 months of age and the spring-grown seed tubers of 2.5 months of age. The former were harvested in May by planting the seeds in December in Ehime Prefecture and the latter in June by planting the seeds in March in Hyogo Prefecture. These were planted early in September in the field, and the growths and yields were compared. The winter-grown seeds sprouted more than 20 days earlier and yielded the tubers over nine times as much as the spring-grown seed. The results from using the winter-grown Irish Cobbler seed tubers were by no means inferior to those from using Unzen, one of the standard variety in the potato fall culture. This suggests the possibility of introducing a potato variety of more superior quality in the fall culture.
