Gladiolus, a genus of flowering bulbous plants commonly called as Queen of bulbous plants has great commercial value as cut flower crops and decorative garden plants. Approximately 255 species of gladiolus are present and the majority of modern day cultivars originate from a variety of genetic backgrounds. Modern cultivars are tetraploids with chromosome numbers ranging from 2n = 30 to 120. Breeding new gladiolus cultivars via genetic engineeringGenetic engineering or traditional crossbreeding is only achievable in circumstances where substantial genetic resourcesGenetic resources are available. In recent times, numerous untamed Gladiolus species have faced extinction due to urbanization and globalization.
