Abstract: An investigation, “Evaluation of Dahlia hybrids (Dahlia variabilis L.) Under Allahabad Agro Climatic Conditions” was carried out in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, during the year 2017-2018. The experiment was laid out in simple randomized block design with three replication and thirteen treatments with a view to find out the overall evaluation of different hybrid varieties of Dahlia viz. Santasy Ma, S.P. Kamla, Kenya Yellow Spot, S.P. Glory of India, Kenya White, Kenya Blue, S.P. Sri Radha, Mangal Pandey, Eternity Sport, Bhikkus Buddha, Bhikkus Mother, Bama Khapa, on the basis of different growth, yield and tuberous root parameters. Maximum plant height was found in the hybrid Bhikkus Buddha (70.14 cm). Maximum plant spread was found in hybrid Bhikkus Buddha (52.20 cm). Maximum number of primary branches was found in hybrid Bhikkus Buddha (12.33). Maximum number of leaves was found in hybrid Bhikkus Buddha (32.29). Minimum number of days required for first bud emergence from planting (38.95 days) was found in hybrid Mangal Pandey. Maximum diameter of fully opened flower (23.55 cm) was found in hybrid S.P. Romia. Maximum weight of single flower (104.63 g) was found in hybrid S.P. Romia. Maximum flower duration (15.33 days) was found in S.P. Romia. Minimum number of days required for complete flower opening after bud emergence (7.23 days) was found in hybrid Bama Khapa. Maximum numbers of flower per plant (13.34) was found in hybrid Bama Khapa. Maximum flower yield per plant (810.23 g) were found in hybrid S.P. Romia. Maximum flower yield (28.19 t/ha) was found in hybrid S.P. Romia. Maximum weight of single tuber (122.05g) was found in hybrid S.P. Romia. Maximum number of tuber per plant (11.24) was found in hybrid S.P. Romia. Maximum yield of tuber per plant (426.30 g) was found in hybrid S.P. Romia. Maximum tuber yield (11.22 t/ha) was found in hybrid S.P. Romia.
