| Outline of Final Research Achievements |
The “Flecked” mutant of torenia (Torenia fournieri Lind. ex Fourn.) , which has highly mobile transposon Ttf1, generates new mutants in the selfed progeny in high probability. We isolated various mutants including the ones bearing doubled flowers, large flowers and flowers partially with radially-symmetrical appearance; those traits are generally seen in highly-bred floricultural plants. Genes responsible for those mutations were identified and analyzed to elucidate the molecular mechanisms conferring the mutated traits. Those mutations were integrated by cross pollination to obtain the lines bearing doubled and large flowers with radially-symmetrical appearance.
