Abstract

The inheritance study found that the purple root epiderm (Pe) and cortex (Pcx) colours were monogenically dominant over the yellow epiderm (ye) and cortex (ycx), respectively.
In contrast, the yellow core (Yc) colour was dominant over the purple core (pc) of carrot root and regulated by a single dominant gene, implying that dominant genes could be used to exploit root colour heterosis.
Flavonoid profiling of carrot populations revealed the presence of three acylated compounds (cyanidin 3-xylosyl (sinapoyl glucosyl) galactoside (Cyx3SGG), cyanidin 3-xylosyl (feruloyl glucosyl), galactoside (Cyx3FGG) and cyanidin 3-xylosyl (coumaroyl glucosyl) galactoside (Cyx3CGG)), and two nonacylated compounds (cyanidin 3-xylosyl (glucosyl) galactoside (Cy3xG) and cyanidin3-xylosylgalactoside (Cy3xGG)) of five cyanidin derivatives of anthocyanin compounds in roots of the black-purple, rose-purple, red-purple, and grey-purple colours.
