An experiment on Indian mustard (Brassica juncea L. Czern and Coss), for divergence studies under rainfed condition, was conducted in Randomized Complete Block Design (RBCD) accommodating 50 genotypes, from various Rapeseed and Mustard centres located across country, randomly in three replications during Rabi 2015-16 at the research farm of Tirhut College of Agriculture, Dholi, Muzaffarpur. Analysis of variance revealed considerably exploitable variability for all the 25 traits. Euclidean and Tocher clustering methods, accommodated Rajendra Suphlam in oligo-genotypic cluster VIII as most divergent genotype. Rearranging fence – sitter genotypes into sub-clusters and rescaled main group through Euclidean method, Varuna and Pusa Bold grouped with Pusa Mahak and exhibited maximum intracluster distance. | Genetic diversity analysis among Indian mustard Brassica juncea L.
