Abstract

The present investigation was carried out in kharif season of 2005–2006. All the genotypes were grouped into five clusters based on D2 values, which exhibited no association between geographical and genetic divergence. The intra-cluster distance was minimum for cluster IV and maximum in cluster II. The maximum distance at inter-cluster level was between clusters I and clusters IV followed by II and IV which may serve as a potential genotypes for hybridization programme. On the basis of mean performance of different clusters, genotypes having high yield along with fruit diameter, fruit index and average fruit weight were observed in cluster V having genotypes like DBR-31 (Delhi), Green Long (Kalyani), KS-335 (Kalayanpur), G-190 (IARI, Delhi), DBR-8 (IARI, Delhi), SL-91-2 (Pantnagar), SL-190-10-12 (Panipat), Swarna Shree (Ranchi), ABR-1 (Anand).
