Abstract

Genetic make-up of Brassica crops has been playing a major contributory role towards its enhanced production. The exploitation of genetic variation among races and gene pools in oilseed Brassica is essential as considerable diversity exists in the set of plants. In the present investigation, the isolated
DNA from 20 Brassica genotypes including exotic, Indian and few mutant varieties were subjected to 40 RAPD primers among which 31 detected polymorphism. A total of 240 DNA fragments were generated by the 31 primers. Cluster analysis of 1 - 0 bivariate data using UPGMA method delineated the genotypes into 4 groups and the data was further used for constructing a dendrogram.
