Abstract
The study was conducted at the experimental field of Olericulture Division, Bangladesh Agricultural Research Institute, Gazipur during 2018-19 to assess the extent of genetic diversity among 26 eggplant germplasm. The collected germplasm originating from local and exotic sources were subjected to cluster analysis. The inter-cluster distance in all cases was larger than the intracluster distance. Maximum inter-cluster distance (17.73) was observed between germplasm of cluster IV and V followed by cluster II and IV (16.39) and minimum was found between germplasm of cluster II and V (4.41). The highest intra cluster value (3.40) was observed in cluster I. Cluster III was responsible for second highest values viz., number of marketable fruit (23.40), average fruit weight (187.00 g), fruit length (18.60 cm), fruit diameter (6.22 cm), fruit yield (56.84 t/ha), while cluster IV was exhibited highest mean value for average fruit weight (228.33g), fruit diameter (7.40 cm), fruit yield (4.64 kg/plant), fruit yield (60.36 t/ha). Considering the group distance and intergenotypic crosses between the members of cluster II and IV and cluster IV and V would exhibit high heterosis and is also likely to produce new recombinants with desired traits. But in case of the cluster means values and yield contributing performance cluster III and cluster IV performed well. Therefore, inbreds belong to cluster III, cluster IV and cluster V will be given higher priority for crossing in future eggplant hybridization programme.
