Abstract

The relationship between the flower color and anthocyanin composition of petals was investigated in 13 cultivars of Leschenaultia species and interspecific hybrids. Five anthocyanins, including cyanidin 3-glucoside (Cy 3G) and cyanidin 3-(6-malonyl)-glucoside (Cy 3MG), which have never been reported in Leschenaultia, were identified. Major anthocyanins of petals were Leschenaultia Blue Anthocyanin 1 (LBA 1), demalonyl LBA 1 and LBA 2 (Saito et al., 2007) in cultivars with blue and violet-blue flowers, and Cy 3G and Cy 3MG in those with red and red-purple ones. Regarding the flower color from yellow-orange to red-purple, decreases in the hue values (b*/a*) of these flower colors were responsible for decreasing carotenoids and increasing Cy 3MG and Cy 3G.<br>
