Abstract: The investigation on "Genetic diversity studies in safflower germplasm (Carthamus tinctorius L.)” was undertaken to estimate the extent of diversity and to estimate the contribution of each character towards genetic diversity. The set of 63 genotypes along with three checks 'A-1, PBNS-12, PKV Pink' were evaluated at the field of Oilseeds Research Unit, Dr. PDKV, Akola during rabi 2018-2019. Based on measurements of genetic diversity by Mahalanobis D² distance and grouping by Tocher’s method, these genotypes were grouped into ten clusters. Clusters VI and VIII (3896.92) had maximum average inter cluster distance followed by clusters X and VIII (3096.12), clusters III and VI (2772.88), clusters II and VIII (2383.65), clusters V and IV (2296.31). Seed yield per plant (25.69%) contributed maximum towards genetic divergence followed by days to maturity (18.41%), days to 50% flowering (16.08%), number of seeds per capitulum (12.82%) and plant height (10.58).
