Abstract
Abstract Three recent cultivars of potato (Solarium tuberosum L.), released by Crop Research Division (viz., ‘Iwa’, ‘Tekau’, and ‘Kaituna’), together with ‘Ilam Hardy’, were assayed for total glycoalkaloid content soon after harvest and after storage for 2, 4, and 6 months at 10°C. Total glycoalkaloid contents were generally low but were doubled by exposure to light. Iwa had the highest level of glycoalkaloid but, even when green, its glycoalkaloid content was still well below the 20 mg/100 g whole tuber level considered unsuitable for human consumption. Glycoalkaloid levels increased very slightly during storage.
