    BSTRACT The present investigation entitled, “Evaluation of dahlia (Dahlia variabilis L.) dahlia for growth and flowering characteristics under sub-montane, sub-tropical low hill zone of HP” was carried out at the Experimental Farm of Regional Horticultural Research and Training Station, Dhaulakuan, District Sirmour (HP), Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, during 2018-19 on 24 cultivars of dahlia. The present investigation was carried out to evaluate the dahlia cultivars on the basis of growth, flowering parameters and genetic variability. Field experiment was laid out in Randomized Block Design (RBD) with 24 treatment replicated thrice. Preset findings revealed that on the basis of yield and other qualitative traits ‘S P Kamla’ was found superior to the other cultivars, cv. ‘Bada Kachari’ was found suitable for earliness in flowering, whereas cv. ‘Red Army’ was found suitable for longer flower duration. Cv. ‘Kenya Orange’ had the maximum flower size, ‘Lokeshwar’ and ‘S P Kamla’ cultivars had maximum number of side shoots and cv. ‘Anadinath’ had maximum stem girth. High heritability coupled with high genetic gain was found for characters like leaf area, intermodal length and plant height, moderate estimate of genetic gain was recorded for number of leaves, vase life and flowering duration. Number of flowers was found positively and significantly correlated with plant height, flower stalk length, number of side shoots, plant spread and number of leaves. The path coefficient analysis revealed that flower stalk length, days taken to bud formation, flowering duration, number of leaves, plant spread showed positive direct effect on the number of flowers.
