This project aims to develop new miniature Cattleya varieties and to create novel flower colors varieties of Agapanthus by using radiation-induced mutation breeding. A total of 91 lines of miniature Cattleya have been successfully sown and germinated through intra- or intergeneric hybridization, 302 offspring from 23 hybridizations have flowered, and photographs and characterizations have been conducted. Nine promising individual plants have been selected for tissue culture propagation. Seed collection and tissue culture using small flower stalks for one Agapanthus variety have been completed, and tissue culture callus from two varieties has been established as material for subsequent radiation irradiation.
