Abstract:
A study on genetic diversity was conducted with forty-eight chilli (Capsicum annuum L.) genotypes which were collected from different agro ecological regions of India. Fourteen quantitative characters were taken into consideration. Mahalanobis D2 statistics was employed to study genetic divergence among 48 genotypes and they were grouped into thirteen clusters on the basis of relative magnitude of D2 values using Euclidean method. Cluster I accommodated maximum number (30) of genotypes followed by cluster V (7) and cluster II, III, IV, VI, VII, VIII, IX, X, XI, XII, XIII (each one). The inter cluster distance D2 values was highest between cluster II and IX (13956.99) followed by XIII and XI (10595.24) and cluster X and XI (10183.48). The intra cluster distance ranged from 0.00 (cluster II) to 691.01 (cluster I). The members of cluster I exhibited maximum divergence (intra cluster distance 691.01) followed by members of cluster V (474.76). The inter cluster distance were larger than the intra cluster distances indicating a wider genetic diversity between genotypes of cluster with respect to traits considered. Maximum inter-cluster distance indicates that genotypes falling in these clusters had wide diversity and can be used for hybridization programme to get better recombinants in the segregating generation.
