Abstract: An present investigation entitled “Evaluation of Dahlia (Dahlia variabilis L.) genotypes Under Northern dry zone of Karnataka” was undertaken at Department of Floriculture and landscape, Kittur Rani Channamma College of Horticulture, Arabhavi during the year 2016-17.The experiment was laid out in simple randomized block design with three replication involving 20 genotypes with a view to know the overall performance of different genotypes of dahlia on the basis of different growth, yield and quality parameters. Maximum plant height (122.38 cm), number of branches (13.15), stem girth (1.48 cm) plant spread in E-W direction (59.12 cm), plant spread in N-S direction (58.86 cm) and intermodal length (18.04 cm) were recorded in genotype Hiranmoyee whereas, maximum leaf area (1909.78 cm2) was recorded in genotype Barakanchari. Total chlorophyll content in leaf (4.65 mg/100g leaf) was obtained highest in genotype Hiranmoyee. Minimum days taken for first bud appearance (42.34 days), first flowering (53.34 days),50 per cent flowering (69.90 days) and cent per cent flowering (89.08 days) were observed in ACC-6 whereas, maximum duration of flowering (63.10 days) and duration of crop (157.33 days) were observed in the genotype Zail Singh. Maximum number of flowers per plant (25.30) was found in genotype Hiranmoyee whereas, maximum flower yield per plant (g) was found in Song of India (718.72 g). Maximum weight of single tuber (60.00 g) was found in ACC-2. Maximum number of tubers per plant (10.33) was found in genotype Hiranmoyee whereas, maximum tuber yield per plant (g) was found in Song of India (433.80 g). Maximum weight of single flower (29.88 g) and maximum diameter of fully opened flower (18.22 cm) were found in genotype Song of India. Maximum number of whorls (14) and petals (187.98) per flower were obtained in genotype Barakanchari whereas, maximum petal length (8.50 cm) and petal width (2.97 cm) were obtained in genotype Song of India. Maximum stalk length (23.10 cm) was recorded in ACC-4 whereas, maximum vase life (6.90 days) was obtained in genotype Hiranmoyee. Overall highest acceptability score (4.87) was obtained in genotype Song of India.
