Abstract:
Genetic divergence amongst fifty one brinjal germplasm was premeditated founded on sixteen qualitative and measurable characters. Significant variations were detected among the brinjal genotypes for all the traits studied. D² analysis resolved fifty one genotypes into eight clusters. Most of the genotypes existed in cluster III (23 genotypes); followed by cluster II (15 genotypes); cluster I (08 genotypes). The intra-cluster distance was extreme with the cluster III (78.16) followed by cluster II (50.78) and cluster I (25.46). The germplasm grouped in this cluster may also be diverse genetically. The minimum inter-cluster D² value was observed between cluster V and VI demonstrating the close relationship among the genotypes included in these clusters. The inter-cluster distance was high among the clusters V and cluster VIII. The genotypes grouped in these clusters might be altered genetically and utilized in crossing programme to get good heterotic hybrids or superior recombinants (segregants).
