Abstract:
The study was carried out in 2013-2014 to evaluate growth characteristics of progeny under nursery conditions and for clustering of different breeding system applied in wild pomegranate genotypes at two locations. Phenotypic coefficient of variation (PCV) recorded higher than the genotypic coefficient of variation (GCV) for all characters and narrow difference between PCV and GCV indicated the negligible influence of environment. GCV and PCV values were observed maximum for the number of branches (136.708% and 136.78%). The highest heritability and genetic advance as a percent over mean reported for number of branches. The fruit length showed a highly significant and positive correlation with fruit diameter (r_g = 0.998, r_p = 0,988). The seedling height at 8 month showed highly significant and positive correlation with seedling height at 11-month, no. of branches, leaf area at 8-month, leaf area at 11-month, petiole length, internodal length and collar diameter. Path correlation coefficient results revealed highly significant relationship between collar diameter and other characters. The principal component analysis (PCA) indicated that first principal component (PC I) accounted for 77.059% of the total variation. The maximum inter-cluster distance was observed between crosses T₄S₂ × T₃S₁ and T₄S₁ × T₂S₂, whereas, the maximum intra-cluster distance was recorded between T₄S₂ × T₃S₁ and T₄S₂ × T₅S₁ in cluster I and S₁T₄ and T₄S₁ × T₂S₂ in cluster II.
