Genetic diversity was evaluated among 25 genotypes of Withania somnifera L. Dunal using RAPD marker. The 15 RAPD primers screened amplified 150 bands among which 141 bands (94%) were polymorphic. The Polymorphic Information Content (PIC) values ranged from 0.162 (OPA-05) to 0.422 (OPA-02) with an average of 0.310. A total of five primers detected in the study produced seven unique bands in seven genotypes Jaccards similarity coefficient values ranged from 0.29 to 0.85 with an average of 0.57. Cluster analysis based on Jaccards similarity coefficient using Un-weighted Pair Group Method with Arithmetic Averages (UPGMA) grouped all the 25 genotypes into two major groups. The cluster I is a major cluster consisting of 20 genotypes whereas cluster II which is minor consists of 5 genotypes. The results show that the level of genetic variation was high among the Ashwagandha genotypes.
