title: Effect of genotype and environmental conditions on health-promoting compounds in Brassica rapa.
abstract: It is well-known that a variety of factors (genetic and environmental) affect the ultimate metabolite levels in brassica vegetables, although there is still little information about the role that genetics and environment play on glucosinolates and phenolic levels. Total glucosinolates were more abundant in turnip tops (26.02 μmol g(-1) dw) than in turnip greens (17.78 μmol g(-1) dw). On the other hand, total phenolic content was found in higher quantities in turnip greens (43.81 μmol g(-1) dw) than in turnip tops (37.53 μmol g(-1) dw). Aliphatic glucosinolates were clearly regulated by genotype; in contrast, the effects of environment and genotype×environment interaction on the indolic glucosinolate and phenolic compounds content appeared to be the main effects of variation. Identification of genotypes with enhanced and stable levels of these compounds would provide a value-added opportunity for marketing this crop with superior health promotion to consumers.
