At the college of Horticulture, Mysuru, Karnataka, the study was conducted during 2018 kharif using RBD with two replications. Quantitative characters namely petiole length, leaf length, leaf breadth, bud length, bud breadth, flower diameter, flower stalks length or pedicel length, calyx length, the number of sepals/ calyx teeth, the number of whorls, the number of petals, petal length, the number of stamens, length of the anther, length of the filament, length of the style, length of the stigma, length of the corolla tube and flower bud weight were recorded. High (>20%) genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for bud length, bud breadth, the number of whorls, the number of petals, pedicel length, length of corolla tube, length of filament, length of style, length of stigma and flower bud weight. Moderate (10 to 20%) GCV and PCV were observed for petiole length, leaf length, leaf breadth, flower diameter, calyx length, the number of calyx teeth, petal size and the number of stamen and length of the anther. The phenotypic co-efficient of variation was more than the genotypic co-efficient of variation for all characters studied. The higher (>20%) values of genetic advance over mean (GAM) coupled with very high (>80%) estimates of heritability were observed for characters viz., bud length, bud breadth, flower diameter, calyx length, the number of calyx teeth, the number of whorls, the number of petals, petal size, pedicel length, length of the corolla tube, the number of stamens, length of anther, length of the filament, length of the style, length of the stigma and flower bud weight. Moderate heritability (40-60%) with low GAM was observed for petiole length. The variance due to genotypes was highly significant for all the characters except for length of the leaf.
