A study to analyze the quantitative comparative variation of antioxidant capacity within the Brassica family was undertaken with ten cultivars representing 5 brassica vegetables. It was observed that sprouting broccoli cultivar Pusa Broccoli KTS-1 exhibited significantly highest contents of antioxidants viz., CUPRAC (17.91 µ mol tolox/g) and FRAP (14.34 µ mol trolox/g) whereas, significantly higher contents of total phenolics (6120.0 µg gallic acid/gfw), anthocyanin (3.28 mg/100 g), ascorbic acid (80.832 mg/100g of sample), lycopene (8.02 mg in 100 g sample), total carotenoids (52.82 mg/100g) and β–carotene (11.32 µg/100 g) were recorded in kale cultivar KTK-64 in comparison to other vegetables. High genetic advance coupled with high heritability was observed for all the traits which is attributed to considerable additive genetic effects and selection for these traits would be most effective. CUPRAC has shown significant and positive correlation at both genotypic and phenotypic levels with all the other 7 traits whereas FRAP was significantly correlated with total phenolics and anthocyanin only. Based on D2 analysis the 10 genotypes were classified into 4 clusters. The cluster IV had maximum 4 genotypes and cluster II had only one genotype.
