The experiment was laid out in a RBD with three replications. Twenty five genotypes of French marigold were evaluated for various growth and yield parameters. Analysis of variance showed significant difference among all the genotypes for all the characters under study. Maximum plant height (68.80 cm) and flower weight (3.89 g) was obtained in genotype ‘ms7x Bonita Bolero’. Genotype ‘ms10x Spray Boy’ recorded maximum plant spread (52.34 cm), number of flowers per plant (100.23), flower weight per plant (380.37 g) and flower yield per square meter (6.08 kg). The genotype ‘ms sx Spray Boy’ recorded maximum flower size (6.37 cm), minimum days taken to bud formation (28.91) and minimum days taken to flowering (36.94). Maximum duration of flowering was recorded for the genotype ‘ms 6 x FM-786’ (62.00 days). Weight of flowers per picking, flower yield per square meter and flower weight exhibited high coefficient of variation, high heritability and high genetic gain. Flower yield per square meter had significant positive association with plant height, plant spread, duration of flowering, flower size, flower weight, number of flowers per plant and weight of flowers per picking. The genotypes ‘ms 10x Spray Boy’ and ‘ms sx Spray Boy’ were promising as they had many desirable traits.ennullThesis
