Summary

Thirty-one toria genotypes were grown in 12 artificially created environments in order to study genetic divergence. D2 estimates based on 12 characters were used in obtaining the clustering pattern and inter- and intracluster distances. Selection of divergent parents has been made in three ways, i.e., on the basis of (a) genetic divergence exhibited when grown in the richest and most productive environment; (b) stable and consistent values of divergence over all 12 environments and (c) pooled analysis. Out of 31 genotypes, on the basis of stability, high yield and divergence six genotypes were found to be suitable for use in a breeding programme.
