Ogura-based cytoplasmic male sterility (CMS) system is widely used for hybrid seed production in Brassica vegetables. The adverse effects associated with the introgression of Ogura cytoplasm on nutritional quality of cabbage are still unknown. Therefore, the effect of Ogura cytoplasm introgression on different quality traits in 17 lines of cabbage (Brassica oleracea var. capitata L.) was investigated. Experimental results revealed that introgression of Ogura cytoplasm altered different quality traits significantly. In general, the concentration of different nutritional compounds increased 3–5 times in some lines, while a 4–5-fold reduction was noticed in others. However, a drastic elevation in the concentration of cupric ion reducing antioxidant capacity (CUPRAC) and ferric reducing ability of plasma (FRAP) was observed in the CMS lines RRMA (29 times) and 5A (78 times), respectively. On the other hand, the amount of CUPRAC, anthocyanin and lycopene reduced severely in the CMS lines 9A (27 times), 1A (44 times) and CH2A (16 times), respectively. This alteration in different quality traits might be attributed to compatible / incompatible nucleo-cytoplasmic and mitochondrial gene interactions associated with the introgression of alien cytoplasm. Therefore, best performing CMS lines, viz. RRMA, RJA, PMA, 208A and 5A, with increased concentration of different nutritional compounds may be utilized in future breeding programs for quality improvement in cabbage. The positive correlations obtained between different quality traits offer the chances for selection of the genotypes with superior multiple quality traits. Further, outcomes of principal component analysis (PCA) and cluster analysis will aid in selection of suitable parental lines for quality F1 hybrid development in cabbage.
