Abstract:
Eleven different cultivars of chrysanthemum were validated for in vitro propagation from ray floret explants. Analysis of variance revealed significant differences among total microbial contamination, explant survival, per cent callus induction and regeneration, number of days required for callus induction, number of shoots regenerated per explant and culture establishment index. The early callusing cultivars were found to be more successful compared to late callusing ones. The earliest callusing cultivars, New Man and Urban Red exhibited greatest culture establishment index values whereas, the late callusing cultivar, Candor Pink recorded the least culture establishment index.
