Abstract:
The present experiment was conducted at Department of Horticulture, Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani.(Maharashtra) during the year 2019-2020 in Factorial Randomized Block Design (FRBD) of three replications. The present work was undertaken to observe the response of chrysanthemum varieties V₁-Pink Cloud,V₂- Devi and V₃-Bidhan Agnisikha over EMS T₁ -0.05%, T₂ -0.1%, T₃ -0.5%, T₄ -1.0%, T₅- Gamma rays 0.5 kR, T₆ -1.0 kR, T₇ -1.5 kR, T₈ -2.0 kR, T₉ - Control treatments. The different treatments to rooted cuttings of chrysanthemum varieties with EMS and gamma rays had significantly influenced the vegetative and flowering characters and also created the variability. Significant reduction occurred in both EMS and gamma rays treated seedlings of chrysanthemum varieties in terms of plant height, branches per plant and leaf area. The higher dose of EMS and gamma rays delayed the flower bud initiation, flower formation and 50% flowering.
