Abstract

An experiment was laid out in a randomized block design (RBD) with three replications to evaluate 10 genotypes of rose for various vegetative and floral traits to ascertain genetic parameters such as variability, heritability, genetic (GCV) and phenotypic (PCV) coefficient of variations and genetic advance. Morphological characterization was done for different morphological traits and genetic diversity of rose species based on morphological characters. The mean performance of cultivars for quantitative traits revealed that cv. First Red exhibited maximum for most of the growth, flower as well as physiological characters viz., plant height (137.38 cm), internodal length (7.31 cm), stem girth (1.03 cm), bud length (3.59 cm), stalk length (42.00 cm), flower diameter (9.18 cm), number of petals per flower (43.33), self life (17.33 days), vase life (12.33 days), number of flowers per plant per year (168.50). It also took minimum days to bud sprouting from bud visibility (13.83 days) and half bloom (14.83 days) which was desirable. High heritability coupled with high genetic advance was observed in the character number of flowers per plant per year which indicated that apparently this character was more governed by additive gene effect.
