Abstract:
An investigation was undertaken to study the genetic divergence of 122 coriander genotypes subjected to non- hierarchical Euclidean cluster analysis for 11 characters. Based on analysis 122 genotypes were grouped into 12 distinct non-overlapping clusters. Cluster-VIII was the largest comprising 22 genotypes, followed by Clusters-IX (14). Cluster V, VI, II XII, IV, III, VII and X having 13, 13, 11, 10, 9, 8, 7 and 7 entries, respectively. Maximum intra-cluster distance was observed for cluster VI (165.37) followed by cluster V (142.19), cluster IV (95.10), cluster VII (91.45), cluster II (73.00) and cluster I (65.01). The maximum inter cluster distance was observed between cluster VII with XI (2752.43), followed by cluster VII with cluster VIII (2415.95). Whereas, the minimum inter-cluster distance was found between clusters I and III (108.23), followed by cluster III and IV (110.56). As regards cluster means, Clusters-XI, XII, II and VIII, VI and Clusters-XI performed better in most of the biometric characters studied. The high per cent contribution towards genetic divergence was exhibited by the plant height (59.25%), followed by umbels per plant (36.05%). Highlights • Vast inter-cluster distance was found between cluster VII with XI and cluster VII with VIII. • Cluster XI recoded highest cluster mean value for yield per plant, umbels per plant and branches per plant. Whereas, Cluster XII recorded the highest value for umbelletes per umbel, umbels per plant and branches per plant. • The plant height and umbels per plants contributed maximum towards genetic divergence
