The present investigation was carried out at College of Horticulture, Bagalkot during Kharif2019-2020. Thirty eight chilli genotypes were evaluated for assessing genetic divergence for exploitation in breeding programme aimed at improving yield potential by using MahalanobisD2 statistics. The genotypes showed significant variation for most of the traits like number of primary branches, number of secondary branches, number of fruits per, capsaicin content, fruit color and green fruit yield per plant indicating sufficient genetic variability and scope for better crop improvement. Genetic diversity analysis, based on D2values grouped into eight clusters with highest inter cluster distance of 14.39 between cluster V and VI. Based on D2values, the test genotypes were grouped into eight clusters and among them, cluster I was the largest with 18 genotypes, followed by Cluster II with 8 genotypes, Clusters VI and IV had 4 genotypes, whereas clusters III, V, VI and VIII had solitary genotypes. Intra cluster distance was found highest in Cluster VIII and V (23.54), followed by followed by clusters IV and V (D2= 22.79), clusters III and VIII (D2= 20.89), clusters II and IV (D2= 20.40), clusters IV and VI(D2= 20.16), cluster I and cluster V (D2= 20.09), clusters III and IV (D2= 19.29), cluster I and cluster VIII (D2= 18.36), clusters V and VII (D2= 18.15), clusters VI and VIII (D2= 18.12), clusters IV and VII (D2= 17.35), clusters I and VII (D2= 17.21), clusters VI and VII(D2= 17.07), clusters II and VI (D2= 16.95), clusters II and VII (D2= 16.94). The lowest inter- cluster distance between clusters III and V was observed (D2= 7.76).Presence of significant difference for number of fruits per plant, test weight among the genotypes provides an opportunity to identify suitable genotypes through breeding programmes.
