 ABSTRACT

An experiment was carried out in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during 2016-18, to study Morphological characterization of double tuberoses (Polianthes tuberosa L.) based on DUS guidelines in Assam condition. The experiment was laid out with four double tuberose genotypes in Randomized Block Design (RBD) with four replications. Results indicated that morphological traits based on DUS guidelines contributing largely to the variability were those related to leaf colour, leaf variegation, pigmentation at leaf base on abaxial side, bud and flower colour, flower type, rows of tepal, tepal tip, infloresecnece, flower shape, flower tube shape, tepal colour on abaxial side, bud length, flower diameter and days taken for flowering. Morphological characterization showed distinct differences in six floral characters and one foliage (vegetative character) characters.

Key words: Tuberose, Morphological Traits, DUS, Genotypes, Floral Characters
