The present investigation was carried out in UAS, Dharwad. Twenty six genotypes of marigold were evaluated for twelve growth, flowering and yield attributes to study their genetic parameters such as variability, heritability, genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV). All traits showed significant difference among the genotypes. The maximum value of GCV and PCV were recorded for number of petals per flower and plant height. The highest broad sense heritability was recorded for flower yield (t/ha), flower yield (g/plant), number of flowers per plant, flower diameter and number of petals per flower. Highest genetic advance over mean was recorded for plant height, flower yield (t/ha), flower yield (g/plant), flower diameter and internodal length. High heritability and genetic advance as percent mean are due to additive type of gene action.

Key words: Genotype, Genetic advance, Heritability, GCV, PCV.
