Genetic Divergence Studies in Rapeseed-Mustard Genotypes under Gangetic West Bengal Condition

Abstract

The field experiment comprising 68 Rapeseed-Mustard genotypes was conducted during Rabi 2019-2020 at Jaguli Instructional Farm, Mohanpur, BCKV, West Bengal. Morphological characterization and grouping of 68 Rapeseed-Mustard genotypes by D² analysis, revealed that genotypic differences for all most all the traits were highly significant indicating considerable amount of genetic variability for the characters under study. Sixty-eight genotypes were grouped in to twelve clusters based on Mahalanobis D² statistics. Cluster X had maximum number of genotypes. It is evident from the inter cluster distance that the most divergent clusters were V and XII followed by cluster I and V suggesting wide diversity between them and the genotypes in these clusters could be used as parents in hybridization program. The cluster means of fifteen characters in D² statistics were observed basis on which   genotypes from these different clusters may be utilised as source lines for development of Rapeseed-Mustard varieties with high yield, early maturity and other desirable characters in crossing program.
