Test of radio-sensitivity is important to use as a recognizable effect of radiation. The optimal doses usually create maximum variability. Indigofera zollingeriana, as forage with potential high nutrition, has no report yet for radio sensitivity to gamma rays. The aims of this research were to know radiosensitivity, optimal doses, and growth of M1 generation from each source of materials of I. zollingeriana irradiated with gamma rays. Seed, plantlets, callus, and seedlings were tests for radiosensitivity by gamma rays. Doses level of Gamma rays were: 0 until 500 Gy. The value of LD50 of each material was evaluated using Curve-fit Analysis. Parameters of growth from each material were observed for 4-6 weeks after planted. Research showed that the sensitivity of each doses level was different for each material. The optimal doses from each material were significantly different curves for LD50. Observation of each irradiated material showed different growth from control.
