Abstract: Tuberose (Polianthes tuberosa L.) is one of the most crucial tropical ornamental bulbous flowering plant, for economic trade used as cut and loose flower due to its charming and lovely fragrance. In the present study, genetic variability among 16 double type tuberose genotypes was studied using morphological traits. As per mean performance Bidhan Rajni-13 attained highest with respect to Plant Height, Spike length, Rachis length, Spikes per Plot and Weight of spike. Bidhan Rajani 19 performed highest in case of number of leaves, Leaf Width and number of Flowers. Bidhan Rajani 14 showed highest number of tillers. Bidhan Rajani 22 showed highest in flower length. Subhasini Double attained highest in flower breadth. The maximum weight of five flowers was shown in both Calcutta double and Bishan Rajani 23. The maximum GCV was observed in case of number of leaves (29.86%). High heritability and high GA had been found for number of leaves, and Rachis Length for double type genotypes.
