Induced mutation by gamma-ray irradiation is one way to increase genetic variability of plants. This research used gamma-ray irradiation on low doses (micro mutation). The aim of this research was to know the response of doses level by micro mutation on gamma-ray irridation to the growing and development of Argomulyo variety of soybean [Glycine max (L) Merr]. The seeds were irradiated by gamma-ray micro mutation doses, namely 0 gray, 50 gray, 100 gray, 150 gray, and 200 gray. Variations that were obtained of each character at generation M₁ and M₂ influences plants growth and development either through qualitative and quantitative that finally will influence plant’s production. The average highest genetic variation at M₂ generation of soybean was on 200 Gray doses. Results of the research indicated that gamma-ray irradiation on 200 Gray doses effectively caused by plant variation genetic.
