Genetic variability with respect to vegetative and floral traits in carnation (Dianthus caryophyllus L.)

Evaluation of sixteen genotypes of carnation indicated that plant height of full flowering stage and stem length was found to be maximum in var. Master. Maximum number of leaf pair per stem was found in var. Ferato. For flowering characters, var. Piax Dover took minimum days taken to bud opening, while maximum flower diameter, flower duration and minimum per cent of incidence of insect pest damage was observed in var. Tabour and minimum per cent of incidence of disease was found for var. Ferado. The coefficient of variation, both at genotypic and phenotypic levels, was maximum for per cent of incidence of disease, incidence of insect pest damage, flower yield/m² and leaf pair/stem. Higher values for genetic advance as per cent mean were recorded for incidence of disease (53.85%), flower yield/m2 (39.20%), leaf pair/stem (35.16%).
