An experiment was conducted to find out the influence of gamma rays dose i.e. 2 kR and 4 kR along with untreated (control) in different varieties of tuberose viz., Shringar, Calcutta Double, Vaibhav, Pune Local Single, Arka Nirantra, Sikkim Selection, Prajwal, Hyderabad Single, Phule Rajani Single, Calcutta Single, Mexican Single, ACC No.7, GKTC-4 and ACC No. 9. Experiment was laid down in Randomized Block Design with three replications. 4 kR dose of gamma ray does not sprout due to lethal effect. Early sprouting was recorded with 2 kR treatment as compared to control. Maximum number of leaves per plant was recorded with control followed by 2 kR. Maximum width of longest leaf was noticed in control which was significantly higher than 2 kR. Maximum leaf area index and plant height was observed with control which was at par with 2 kR treatment. Early spike emergence was recorded with 2 kR dose of gamma irradiation. Maximum length of spike was noticed in control. Maximum number of florets/spike was recorded with control when compared to 2 kR dose of gamma irradiation. Maximum diameter of floret was noticed in control as compare to 2 kR. Control plants resulted maximum duration of flowering. Maximum number of spikes m2 was recorded with control. Interaction of gamma doses and different varieties found non- significant on number of spike per m2. Maximum days taken to first floret withered was noticed in control as compare to 2 kR treatment of gamma dose. Earliest 50% flowering was noticed due to gamma irradiation dose at 2 kR. The highest percentage of opened floret was noticed in control. Maximum water uptake and vase life was found in control.
