| Abstract | Gamma ray irradiation is a conventional technique used to produce mutants in plant breeding. The aim in this research was to develop new cultivars of Torenia (Linderniaceae) for the ornamental market. Leaves of Torenia fournieri Lind. were exposed to acute (Cs-137) gamma ray irradiation at 0, 20, 40, 60, 80, 100 and 120 grays. After culturing, the number of plantlets, plant height and root length of surviving plants was measured 60 d after irradiation. The results showed that the LD50 was 63.65 grays in diploid plants and 72.00 grays in polyploid plants. Red colored leaves were observed in some plants after acute gamma irradiation treatment, for example in the 20-gray treatment group for diploid Torenia and in the 80-gray treatment group for polyploid Torenia. The plants with red leaves were selected for development in the future. |
