Using the Mahalanobis D2 statistic, the genetic divergence among 32 genotypes of brinjal for 23 characters was examined. On the basis of the relative magnitude of the D2 values, the genotypes were divided into eight clusters. The largest of the eight clusters, cluster I, had 18 genotypes. It was followed by cluster V (five), cluster III (four), and the remaining clusters, which each had a single genotype. The largest intra-cluster distance (8277.51) was in cluster V, which was followed by cluster I (4488.09) and cluster III (3908.52). The remaining clusters had very small intra-cluster distances. The highest inter-cluster D2 value (23195.60) was found between clusters III and VI, while the lowest value (5777.13) was found between clusters IV and VI. In cluster VI, the mean value for almost all of the characteristics was greatest. Maximum genetic divergence was caused by traits including fruit weight, days to first harvest, number of fruits per cluster, and percentage of fruit set in pseudo short-styled flowers.
