Chrysanthemums are widely cultivated and have a significant market value due to their popularity as ornamental plants and their traditional medicinal uses. The global chrysanthemum market includes various segments, such as cut flowers, potted plants, and medicinal products. Therefore, the present investigation was carried out with title at the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh during the Winter-2022-23 with a view to determine the effect of different doses of EMS mutagen application on chrysanthemum variety Sunburst cushion for its growth quality and to work out the economics of various treatments. Under this experiment, overall, 7 treatment was prepared by soaking planting material in different doses of EMS mutagens prepared for five hours each, Treatments comprised of T₀ (Control), T₁ (0.5% EMS mutagen)_, T₂ (0.75% EMS mutagen), T₃ (1.0% EMS mutagen), T₄ (1.5% EMS mutagen), T₅ (1.25% EMS mutagen), and T₆ (2.5% EMS mutagen). The current study found that the use of EMS mutagen at lower concentration had a significant positive impact on the survival, growth, and development of chrysanthemums. Among the treatments tested, T₁ showed the most favorable results in terms of leaf width, leaf length, stem length, number of flowers per plant, early flowering. T₁ was composed of 0.5% EMS mutagen.
