A study was conducted to determine the extent of genetic divergence with respect to 16 quantitative characters in 144 sunflower genotypes consisting of 66 germplasm accessions, 75 inbred lines and three checks at the University of Agricultural Sciences (UAS), Bangalore, India. Univariate and multivariate analyses of variance confirmed the presence of significant differences among the genotypes. Mahalanobis' D2 statistics indicated the presence of substantial genetic diversity. Higher D2 values were observed among the inbred lines than in the germplasm accessions. Clustering of the genotypes resulted in the formation of seven and 14 clusters in the germplasm accessions and inbred lines, respectively. Some clusters were unique having only a single genotype, while clusters with up to 55 genotypes were also formed. Factors other than geographic origin appeared to be a potent source of genetic diversity. The intercluster distance showed that clusters II and V among the germplasm accessions and clusters XI and XIII among the inbred lines were most divergent. Clusters were also demarcated with respect to characters they excel and/or for which they were inferior.
