The herbal medicine (Lallemantiaroyleana) has many effective ingredients. Balengo seeds have various benefits, including bloating, constipation, dry cough and asthma. Given the importance of genetic diversity in plant breeding, artificial mutation can be used to create diversity. To this end, we investigated the effects of different gamma radiation doses (0, 500, 800, 1100, 1400, 1700 and 2000) on germination properties of Shiraz balm seed and determining the appropriate dose of gamma radiation to induce mutation through a complete design. Randomized with 4 replications. Analysis of variance showed that the effects of different doses of gamma ray on shoot length, root length and seedling length of Shiraz balm were significant at 1% probability level. The shoot length increased by 500 Gy of gamma irradiation but the total root and shoot length decreased by gamma irradiation. However, a dose of 500 Gy was found to be suitable for mutation in Balengo seeds, which can be recommended to artificially increase the diversity of these species.
