Abstract

Difference in 105 genotypes of toria germ plasm was evaluated by statistical methods. Oil content, fatty acid composition and glucosinolate content was estimated and data obtained for various characters were subjected to statistical analysis i.e. analysis of variance, measurement of genetic divergence. Analysis of variance indicated that all the genotypes were significantly different from each other for all the characters. 105 genotypes, included in the study were grouped into 8 clusters. Genotypes occupying one cluster may also have little diversity and selection of parents within the cluster may also be useful. This information on relationship within and between genotypes of the same species will be valuable for organizing germ plasm and selecting parents for breeding purposes.

Key words: Brassica campestris, toria, genetic divergence, variability
