Abstract:
The research experiment was conducted to study genetic diversity for quantitative traits among genotypes of brinjal (Solanum lycopersicum L.). The investigation was conducted during Rabi, 2020-21 at the Main Experiment Station, Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology Narendra Nagar, (Kumarganj), Ayodhya (U.P.) using Mahalanobis D²statistic. The 40 genotypes were grouped into five clusters, indicating the presence of diversity among the genotypes for different traits. The cluster first had the highest number containing 24 genotypes followed by cluster II containing ten genotypes. However, the cluster III, IV and V were containing two genotypes. The maximum intra-cluster distance was recorded within cluster IV (1034.56) and the maximum inter-cluster distance was observed between clusters IV and V (31520.82). Based on cluster mean analysis, the superior and genetically divergent genotypes can be used in crop improvement programme in brinjal.
