An experiment was conducted at Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere to evaluate fifteen marigold cultivars for chlorophyll content of leafs, vegetative growth and yield. Chlorophyll ‘a’ was maximum in cultivar Nilakkotai Local Orange whereas Chlorophyll ‘b’ content and total chlorophyll content was maximum in cultivar Darmapuri Local. The genotype Nilakkotai Local Orange recorded the maximum plant height (104.20 cm), number of leaves per plant (392.47), whereas minimum plant height (66.80 cm), number of leaves per plant (135.53) was recorded in the genotype Pusa Narangi Gainda . In case of flower yield and quality attributes such as number of flower per plant (59.4), flower yield per plant (529.33 g), and xanthophylls content (20.19 mg/g petal meal) was maximum in Nilakkotai Local Orange, whereas minimum number of flower per plant (20.60), flower yield per plant (120.93 g) was recorded in the genotype Dwarf Yellow. Among these marigold genotypes studied, better performance in terms of vegetative growth, flower yield and quality parameters, genotypes Nilakkotai Local Orange, Coimbatore Local orange, Coimbatore Local Yellow were found promising for loose flower production under hill zone condition of Karnataka.
