 ABSTRACT

An experiment was laid out in a Randomized Block Design (RBD) during 2013-14 and 2014-15 with three replications to evaluate ten genotypes of rose for various vegetative and floral traits to ascertain the pattern of morphological variations through metroglyph technique. The mean performance of cultivars for quantitative traits revealed that the cultivar First Red exhibited maximum for most of the characters. In the metroglyph analysis the ten cultivars of rose formed seven clusters based on selected growth and flower characters exhibited by the cultivars viz.plant height, number of flowers per plant per year, number of leaves per plant, internodal length, flower diameter, self life and fresh weight of flower at harvesting. Highest index score was recorded for the cultivar First Red with a total score of (20/21). First Red performed highly for six characters (plant height, number of flowers per plant per year,  internodal length  , diameter of flower, self life and weight of cut flower at harvest) and medium for one character (number of leaves per plant). Tineke and Manuparlae recorded the lowest index score (9/21).

Key words:   Vegetative traits, Floral traits, Metroglyph analysis, Cluster, Index Score
