Abstract: The present investigation was carried at ICAR-IARI Regional Station, Katrain, Kullu, HP during 2016–2017. The activity of different antioxidant compounds & plant pigments in eight genotypes of ornamental kale were estimated. The experimental results on anthocyanin pigmentation profile revealed the presence of yellowish-green or bluish-purple or pink-purple colour in different genotypes of ornamental kale. Further, analysis of variance exhibited significant differences among different genotypes for all quality traits under study. The genotype, KtOK-40-1 recorded highest amount of lycopene (25.36mg 100 g-1), total carotenoids (18.30 mg 100 g-1) & β-carotene (23.56 mg 100 g-1), while concentration of FRAP (1.29 μ mol trolox g-1) & anthocyanin (16.02 mg 100 g-1) was observed maximum in the genotype KtOK-40-1. In the meanwhile, amount of CUPRAC (5.42 μ mol trolox g-1), ascorbic acid (23.83 mg 100 g-1) & phenolics (2582.82 µg gallic acid g-1 FW) was recorded highest in the genotype KtOK-45-1, KtOK-39-1 and KtOK-37-2, respectively. The Pearson’s correlation coefficient analysis revealed a significant positive correlation of lycopene with total carotenoids (0.97) & β- carotene (0.97); total carotenoids with β-carotene (0.99) & ascorbic acid with anthocyanin (0.96). Based on the principal component analysis (PCA), first two components having eigen values greater than one was retained in the analysis because of the substantial amount of variation amongst them (77.68%). Further, loading of different quality traits based on two principal components indicated that CUPRAC, FRAP, anthocyanin & ascorbic acid are the main components of divergence between eight genotypes of ornamental kale, whereas contribution of rest of traits under study was found comparatively less in divergence. Hence, main emphasis should be given on these traits for quality improvement in ornamental kale. Further, neighbour-joining UPGMA dendrogram revealed that based on the trait of interest to be improved distantly placed genotypes can be selected as parental lines for the development of heterotic quality hybrids in ornamental kale.
