Mutagenic effectiveness of EMS was studied on four cultivars of tuberose (Polianthes tuberosa Linn.) cv. Kalyani Single, cv. Kalyani Double, cv. Suvasini and cv. Prajwal by treating them with 2 doses of EMS (0.1%, 0.2 %) .The findings indicated that there was significant morphological variation related to floral character in cultivar prajwal and Suvasini treated with EMS (0.1%, 0.2 %). The findings indicated that mutagenic treatments with lower doses EMS lower doses (0.1%,) resulted in increase in floral size of few florets within a spike.
