Pigment content of pink-flowered strawberry was a quantitative trait controlled by polygenes.
Seven anthocyanin types were detected from pink-flowered strawberry by HPLC–MS.
Among all anthocyanins, cyanidin 3-O-glucoside (Cy3G) was most abundant.
A significant positive correlation was found between Cy3G and parameter a* value.
A coloration mechanism of pink-flowered strawberry was proposed.
