The present paper makes an assessment of genetic variability in ashwagandha [Withania somnifera (L.) Dunal] based on morphological traits related to plant growth habit, root, leaf, flower, berry and seed. Mahalanobis D² statistics was used to classify the 20 accessions collected from different sources. The accessions investigated were grouped into 5 distinct clusters using Tocher's method. Cluster I being the largest comprised 6 genotypes, whereas cluster II, III, IV and V had 1, 3, 5 and 5 accessions, respectively. Clusters II and III were distantly located (13.387), whereas cluster I and III were closet (3.176).
