An experiment was conducted to study a genetic divergence analysis were estimated in 19 genotypes of fennel (Foeniculum vulgareMill.) grown in a Randomized Block Design (RBD) with three replications during Rabi season of 2016-17 at the research farm of ICAR-National Research Centre on Seed Spices, Tabiji, Ajmer (Rajasthan). Mahalanobia D2 statistic indicated wider genetic diversity in the population. All genotypes were grouped into seven clusters on the basis of diversity. Estimates of intracluster distance ranged from 0.00-5.70. The maximum intra cluster distance was observed within cluster I (D=5.70), whereas, III, IV, V, VI and VII showed the minimum intra cluster distance (D=0.00) followed by cluster II (D=4.91). It was maximum in cluster I and minimum in cluster III, IV, V, VI and VII. Tocher’s method of hierarchical cluster analysis was applied to group the varieties. The maximum inter-cluster distance between cluster V and IV was 6.51 and 14.58, respectively. The genotypes falling in cluster II were GF-11, RF-157, RAJENDRA SAURBH, RF-205, AZAD SAUNF-1, CO-1, RF-101 and GF-12, in cluster I RF-178, RF-281, GF-2, RF-143, RF-145 and RF-125, in cluster III AF-2,in cluster IV GF-1, in cluster V AF-1, in cluster VI one HISAR SWARUP, incluster VIIPANT MADURIKA. Clusters I and II showed the highest genetic distance between them. Cluster means showed that, the cluster I showed the highest mean values for plant height (150.83) and the lowest mean value for seed yield per plot (1.08). Among the 13 characters studied for genetic divergence, seed yield per plot (kg) contributed the maximum accounting for 49.12% of total divergence, followed by number of umbles per plant 29.82.
