| This study was conducted to clarify effects on the germination, survival rate of seedlings, growth and variation induction of variants in gamma rays irradiated seed of lilac pink (Dianthus superbus var. longicalycinus) and nursery spiraea (Caryopteris incana). Seed germination and its germination rate were delayed over 90 Gy for lilac pink and 80 Gy for nursery psiraea. Fifty percent lethal time (LT50) level for lilac pink and nursery psiraea were 150 Gy and 100 Gy, respectively. Lilac pink and nursery psiraea were grown dwarf over 120 Gy treatment. We have produced 17 variants of lilac pink in $M_1$ generation, and selected the promising 4 variants in $M_2$ generation. We have also made 7 variants of nursery psiraea in $M_1$ generation, and selected the favorable 8 variants in $M_2$ generation. |
