Abstract: Water lily (Nymphaea spp.) is a perennial aquatic flower plant. We investigated color of 57 hardy water lily cultivars by the Royal Horticultural Society Colour Chart (RHSCC) and International Commission on Illumination CIEL*a*b* scale. High-performance liquid chromatography (HPLC) with photodiode array detection (DAD) and HPLC electrospray ionization mass spectrometry (HPLC-ESI-MSn) identified 14 anthocyanins. Eight compounds were identified in the petals of 119 hardy water lily cultivars for the first time. Multiple linear regression revealed that Dp3Ga, Dp3galloylGa, Cy3Ga(1→2)Ga and Cy3galloylGa compounds were key pigments in petal color. We discuss differences in anthocyanin components between hardy and tropical water lily and blue color breeding of hardy water lily.
