Ten genotypes of French marigold (Tagetes patula L.) were evaluated to investigate the variability parameters and character association for twelve characters. Analysis of variance showed highly significant differences for all the twelve characters. In general, estimates of phenotypic coefficient of variation (PCV) were found to be higher than their corresponding genotypic coefficient of variation (GCV). High broad sense heritability coupled with high genetic advance was reported for number of flowers per plant (h² = 99.62%, GA = 59.78) and flower yield per plant (h² = 99.53%, GA = 133.82), showing additive gene effects and shows the effectiveness of selection of these characters. The yield of flowers per plant exhibited highly significant and positive correlation with number of primary branches (0.862), number of secondary branches (0.738), number of flowers per plant (0.862) and flower weight (0.732). Hence, these characters should be given due consideration during selection for yield improvement in French marigold.
