1. A large amount of solanine was detected in May Queen potato tubers with bitter taste, harvested in Nagasaki prefecture in early Dec., 1976. 2. The effect of light on solanine content was studied in potato tubers of May Queen, Unzen, Tachibana, Simabara and Dejima, from Nagasaki. Exposure to 1,500 lux of light for 20 days increased the solanine content markedly in the peels of the tuber of May Queen and Unzen, and in the inner part of the tubers of May Queen. Solanine content in these parts of Dejima was apparently unaffected by such irradiation. The solanine content in the inner part of the tubers of May Queen exposed to 3,500 lux for 98 days was about 1.7 times as much as that in corre-sponding part exposed to 1,500 lux for 20 days, while such an increase was not observed in the peel. Solanine content in May Queen tubers, exposed to 500, 1,500 and 3,500 lux of light for up to 20 days, was found to increase as light intensity and duration of irradiation increased. More solanine was found to be produced in the middle part than in the inner part of tuber.
