Genetic divergence analysis in niger (guizotia abyssinica cass.)

Abstract

Genetic divergence was studied In 17 genotypes of nlger (Guizotia abyssinica Cass.) using D2 statistic for seven developmental characters. The genotypes were grouped into 5 clusters. The inter-group distance was much more larger than the intra-group distances. Cluster UI showed maximum genetic distance from cluster IV. Genotypes belonging to the clusters III, IV and V might be included in future hybridization program for getting desirable segregants.
