Résumé
A field experiment was undertaken to estimate the genetic variability, divergence studies and to know correlation and path analysisin coriander. Thirty five genotypes were sown in a Randomized Block Design with three replications during rabi 2016-17 at College of Horticulture, Rajendranagar, Hyderabad. The objective of the experiment was to study genetic divergence, variability and also to know correlation among genotypes to use as donor parents in hybridization programmes. The analysis of variance of RBD revealed highly significant differences among the genotypes for all the 23 characters studied. The D2 analysis was carried out for twenty three characters which partitioned the thirty five genotypes into seven clusters. The maximum divergence was observed between cluster VI and IV indicating that the genotype of these cluster are highly divergent. Number of umbels per plant at 60 DAS had more contribution to total divergence. Hence selection of genotype from cluster VI and IV based on number of umbels per plant at 60 DASmay be chosen in hybridization programme for getting good seggregants. High PCV and GCV were recorded in umbels plant-1 (60 DAS and at harvest), umbellets umbel-1 at 60 DAS, number of seeds umbellet-1 (60 DAS and at harvest), seed yield plant-1 and seed yield hectare-1 indicating the existence of wider genetic variability for these traits in the genotypes under study and showing ample scope for selection of these characters.
