Abstract: Thirty one genotypes of African marigold (Tagetes erecta L). Collected from different indigenous sources were evaluated at Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam to know the nature and magnitude of variability among them for different horticultural traits. The study revealed high phenotypic coefficient of variability (PCV), genotypic coefficient of variability (GCV) and heritability estimates coupled with high genetic gain were observed for number of flowers per plant and flower yield per plant indicated the existence of wide range of variations and offers better scope for improvement through selection. The genotype AM-29 gave maximum mean value for number of flowers, flower diameter, individual flower weight, duration of flowering and total flower yield per plant.
