Abstract: Genetic diversity of twenty genotypes of Hibiscus were analysed for various growth and flowering traits. Analysis of variance revealed significant differences among the genotypes for all the morphological traits studied. The twenty genotypes of hibiscus were grouped into six clusters by using Tocher method. Cluster I and II were the largest groups comprising of nine and seven genotypes respectively, while cluster III, IV, V and VI are monogenic clusters i.e. these clusters showed zero intra-cluster. The maximum intra-cluster distance was observed for cluster II (36.77) followed by cluster I (35.40). The highest inter cluster distance was observed between cluster V to cluster VI (D2 = 153.74), followed by between cluster III and cluster V (D2 = 130.20) and minimum inter-cluster distance was recorded between cluster III and IV (39.71). The relative contribution of number of secondary branches per plant at 360 days after planting was maximum to divergence (76.32%) followed by number of primary branches per plant (13.16%) indicating that these characters were considerably responsible for total divergence in the material under study. On the basis of divergence classes analysis, the genotypes HCH-15-001, HCH-15-004, HCH-15-005, HCH-15-008, HCH-15-011 and HCH-15-015 were suggested for further breeding programme.
