An experiment was conducted at the experimental field of Olericulture Division, Bangladesh Agricultural Research Institute, Bangladesh during the winter season of 2017-18. Twenty two bottle gourd genotypes were evaluated to genetic diversity. The genotypes were clustered into five distinct groups with the range of 1 genotypes to 8. The inter-cluster distance in all cases was larger than the intra-cluster distance suggesting wider genetic diversity among the genotypes of different groups. The maximum inter-cluster distance was observed between genotypes of cluster III and IV (15.010) followed by cluster II and IV (12.841) and the minimum was found between genotypes of cluster II and III (5.318). The highest intra cluster value (0.933) was observed in cluster I due to the presence of variations among the genotypes.
