Sixty genotypes of roselle (Hibiscus sabdariffa L.) consisting of 45 indigenous, 11 exotic genotypes and four released varieties were evaluated at three different agro-climatic zones in India viz., North Coastal zone of Andhra Pradesh, Indo-Gangetic zone and Terai zone of West Bengal for seed yield and its contributing characters during Kharif, 2013 and 2014 for ten characters and grouped into six clusters based on D2 analysis. Cluster I comprised of thirty five genotypes followed by Cluster II with thirteen genotypes. Inter-cluster distance was highest between the Clusters III and IV followed by Clusters I and IV, whereas Intra-cluster distance was high for Cluster V which consists of five genotypes. Cluster II recorded highest and high values for yield and its attributing characters followed by Cluster I, whereas, Cluster IV recorded lowest and low values for yield and its attributing characters followed by Cluster V Test weight contributed high for the diversity followed by seed yield followed by seeds per pod and pods per plant. The genotypes belonging to Cluster, II, III and IV viz., AR-80, AS-81-9, AS-81-17, AR-19, AR-71, R-16, AS-81-5, R-67, AR-14, R-48, R-225, R-134, AR-55, ER-60, AS-81-22, AS-80-19, AS-81-2 and REX-34 could be selected as parents in future breeding programme for developing high seed yielding varieties.
