Genetic divergence among 30 eggplant (Solanum melongena L.) genotypes was estimated using Mahalanobis D2 Statistics. The 30 genotypes were grouped into six distinct clusters. Among the different clusters, cluster III consisted maximum number of genotypes (8 genotypes) followed by cluster I and VI (5 genotypes), cluster II, IV and V contained (4 genotypes). The highest intra-cluster distance was recorded for cluster I (1250.024) followed by cluster II (1217.052) and the lowest intra-cluster distance was recorded for cluster-V (389.277). However, the highest inter-cluster distance was observed between cluster IV and V (6815.521) while it was lowest between cluster III and IV (1149.46). The highest contribution in manifestation of genetic divergence was exhibited by days to first flowering, followed by days to 50 % flowering, fruit set percentage and fruit girth. The cluster III showed moderate mean values for all the characters under study except for number of primary branches. Cluster II had highest mean values for number of primary branches and fruit set percentage, Cluster I showed higher mean values for number of fruits per plant, Cluster IV showed higher mean values for plant height and fruit yield per plant, Cluster V showed higher mean values for fruit length, petiole length and test weight while cluster VI had higher mean values for fruit weight, plant spread, days to first flowering, days to 50 % flowering, fruit girth, days to first harvest. Considering the genetic divergence, clustering pattern and mean performance of genotypes for fruit yield and contributing characters 9 genotypes comprising EC-467273, 71-19, Rajendra Baigan-2, Pusa purple long, JB-15, IC-89933, Pant Rituraj and Muktakeshi may be considered as elite genotypes and hybridization involving these genotypes are likely to give desirable segregants for yield and its components characters.
