Gladiolus (Gladiolus hybrida) is an important ornamental plant cultivated world over for its attractive spikes. The commercial cultivation of Gladiolus is based on natural multiplication of corms and cormels. In vitro propagation techniques, is superior to conventional propagation and produces disease free plants in huge quantities. In vitro regeneration of gladiolus cultivars, Sylvia, White Prosperity and Amsterdam was achieved using shoot bud of cormels as an explant. Sylvia variety recorded the best for callus induction and regeneration than other two varieties. The concentration of plant growth regulators affects the regeneration response differently. The highest callus induction rate of 76% explants was recorded on Murashige and Skoog (MS) medium supplemented with 2 mgl-1 2,4-D (2,4-Dichlorophenoxyacetic acid), after 28 days. MS medium supplemented with BAP at mgl-1 exhibited higher shoot proliferating efficiency, shoots per explant in Sylvia variety. | In-vitro multiple shoots production from cormel shoot buds in gladiolus (Gladiolus hybrida)
