Abstract
Lilium longiflorum Thunb., commonly known as Easter Lily is widely propagated by vegetative means for its high ornamental value as a pot plant. Following in vitro technique, mass propagation has been achieved through direct production of bulblets from the explant as well as regeneration from callus. The chromosome analysis of the progeny derived from callus even from long term culture, did not reveal any marked variability in chromosome morphology. The stable nature of callus maintained in modified MS medium in long term culture has been confirmed. Along with rapid growth, the regenerating capacity of calli has been maintained for 3 years of culture in the above medium. Following shake culture, large number of bulblets could be obtained from such differentiated calli within 3–4 weeks. The shake culture technique of calli is ideally suited for securing stable regenerants on a mass scale in this species.
