This research aims to determine the effect of gamma-ray irradiation on the phenotypic of the garlic cultivar Doulu. The study was conducted in April-August 2018. Radiation on the bulb garlic is carried out at the centre of Safety and Meteorological Technology (PTKMR), BATAN, Jalan Lebak bulus Raya No. 49 Jakarta. Bulb planting is done at the research Hall of vegetable crops, Tongkoh village, Berastagi, North Sumatera. The draft used in this study is non factorial group random draft with 6 radiation dose treatment of 0 Gy (Control), 2 Gy, 4 Gy, 6 Gy, 8 Gy and 10 Gy. Each of the treatment levels is repeated as much as 4 and consists of 10 cloves of garlic. The observed quantitative data parameters are growing age, crop height, number of leaves, number of cloves, heavy bulbs, diameter of bulb, heavy cloves and diameter of cloves. The qualitative data parameters observed are bulb structures and bulb forms. Qualitative Data obtained is analyzed using various prints with advanced test of the smallest real difference (LSD). The results shows the irradiation of the influential gamma rays in the height of the plant, the number of leaves, the number of cloves, the weight of bulbs, the diameter of the bulb, the weight of cloves, and the diameter of garlic cultivars Gamma-ray irradiation produces a variety of bulb structures and bulb shapes. The parameters observed were structure and shape bulb based on IPGRI. Results showed that there were differences in the structure and shape of garlic bulbs.The structure of bulb are regular two-fan groups, regular multi-cloved radial, regular quadruple, regular two-cloved, and Irregular. The shape of bulb are Flat, Flat globe, Rhomboid, Broad oval, Globe and Ovate.
