A study on genetic diversity was conducted with 29 Chili (Capsicum annuum L.) genotypes through Mohalanobis’s D2 analysis. Cluster analysis was used for grouping of 29 chilli genotypes and the genotypes were fallen into six clusters. The maximum number of 22 genotypes was included in cluster-I followed by cluster-III with 3 genotypes, Cluster-II, IV, V and VI had one genotype each. The highest inter-cluster distance was observed between cluster I and VI which indicated maximum exploitation of heterosis on hybridization. The least inter cluster distance was observed between cluster II and V. Cluster III (D2=197.76) have exhibited highest intra cluster distance followed by cluster I (D2=193.37). Cluster II, IV, V and VI had only one genotype and hence, the intra cluster distance of this cluster was zero. The contribution of various characters towards the total divergence was recorded the highest for capsaicin (60.34%) followed by number of seeds per fruit (18.23%), dry fruit yield per hectare (9.61%), dry fruit yield per plant (7.64%), weight of 100 dry fruits (2.71%), fruit length and fruit diameter (0.49%), plant spread at 60 DAT (E-W) and fruit yield per plot (0.25%).Thus, it can be concluded that, selection for these traits will be beneficial for future improvement programme of chilli.
