Genetic divergence analysis in niger (guizotia abyssinica cass.)

Abstract

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.
