Abstract

An investigation on the induction of mutation in tuberose was carried out at the Department of Floriculture and Landscaping, TNAU, Coimbatore with the objective of examining the effect of chemical mutagens viz., Diethyl Sulphate (DES) @ 15, 20, 25 and 30 mM and Ethyl Methane Sulphonate (EMS) @ 30, 45, 60 and 75 mM on bulb sprouting, survival percentage and growth parameters. Lower doses (15 mM of DES and 30 mM of EMS) were found to favour bulb sprouting and growth parameters. In general, variations in floral characters were observed invariably in all the treatments except control. The LC50 values fixed for the chemical mutagens were 25 mM for DES and 60 mM for EMS. It was interesting to observe that lower doses of the mutagens had recorded higher values for morphological and floral parameters than untreated control.
