Lal, Nupur Srivastava, Karuna ShankerAbstractPrevailing diversity among germplasm in a crop assists invaluably in crop improvement program. Genetic divergence in 60 germplasm lines of opium poppy was studied based on 13 morphometric characters by using Mahalonobis D2 statistics. The germplasm lines belong to the different eco-geographical origin and are being maintained at CSIR-CIMAP, Lucknow. The ANOVA revealed significant amount of differentiation among germplasm. The genotypes were grouped in eight diverse clusters. Cluster I is the largest group comprises 40 genotypes followed by Cluster II, consisting 12 genotypes and cluster III and IV has 2 genotypes while rest 4 clusters have only a single individual. The maximum intra-cluster distance was observed in cluster IV (93153.35) and minimum for Cluster I (33360.9). Inter-cluster D2 values range from 115261.4 to 4717153. The minimum was between Cluster I and II (115261.4) followed by IV and V (128735.4) and maximum between Cluster I and VII (4717153) followed by Cluster VI and VII (4655531). Based on the mean performance genotypes, G-1 and G-53 can be further selected for exploitation in hybrid breeding program for poppy crop improvement.Graphical abstract
