In this study, in order to create diversity in tuberose,
gamma-ray irradiation treatment was used on mature
bulbs of tuberose with gamma ray doses of 10, 50,
100, 200 and 400 Gy. Some characteristics of control
and treated plants such as survival and sprouting
rate, flowering time, leaf number and size, size and
weight of the florets, number of petals, internode
distance, plant height and stem diameter is measured
in this study. The experiment was performed in a
template design of completely randomization in
a research greenhouse at University of Tehran,
Iran. Experimental results showed that at the dose
treatment of 10 Gy
