The study was undertaken to assess the genetic diversity among 110 sorghum genotypes using D2 statistics. 4 clusters were formed, highest no of genotypes are in cluster –I with 91, followed by cluster –II with 12, next by cluster-IV with 6 genotypes and cluster-III having solitary genotypes. The highest inter cluster distance was observed between cluster II & IV (), Cluster II and III (), I and II (), I and IV () and lowest between cluster III and IV (). Cluster means for 9 characters were as following cluster I had high means for days to 50 % flowering while cluster III recorded the lowest. As seen in the result of first character, cluster I showed low means for 1000 seed weight while cluster III has high means. Panicle weight recorded high mean in cluster IV and low in Cluster I. seed yield/plant has observed high means in cluster I and low means in cluster III. The genotypes in cluster –II and Cluster-III are divergent according to this study and hybridisation programme between these genotype clusters would be rewarding with heterotic response from its progeny. Based on the mean values no single genotype possessed all desirable characters, most yield and yield related attributes is-2834 performed for biomass type’s NSJB-6652. | Genetic divergence study in sorghum (Sorghum bicolor L.) using D2 analysis
