Genetical study on the formation of anthocyanins and flavonols in turnip varieties. Genetical studies on anthocyanins in brassicaceae II
Genetic studies were made on the root color of turnip varieties. In the cross between the red (raphanusin, pelargonidin glucoside) and the white varieties, F1 hybrids were all purple (rubrobrassicin, cyanidin glucoside), and F2 progenies were segregated into three groups: purple (rubrobrassicin), red (raphanusin), and white in the ratio of 9:3:4, respectively. This indicates the presence of two pairs of conditional alleles, as previously found in the case of radish. As to the flavonols in turnip varieties, isorhamnetin and kaempferol were found in the plants forming rubrobrassicin in roots, and only kaempferol in the plants producing raphanusin in roots; whereas isorhamnetin was found together with a trace of kaempferol in the plants with white root.
