Horticultural University, Venkataramannagudem to assess the impact of mutagens on mutagenicity like Mutation frequency on M1 population basis, Mutagenic effectiveness, Mutagenic efficiency and Frequency of albino, xantha and chlorina mutants in turmeric. The experiment was laid out in factorial randomized block design and replicated thrice under open field conditions. Rhizomes are treated with gamma rays (25 Gy and 50 Gy) and EMS (250 ppm, 500 ppm and 1000 ppm) along with control. Maximum mutagenic frequency, effectiveness and efficiency was observed in25 Gy, 250 ppm EMS and combination of 25 Gy + 250 ppm EMS and minimum was recorded in 50 Gy gamma rays, 1000 ppm EMS and combination both 50 Gy + 500 ppm EMS and 50 Gy + 1000 ppm EMS .
