Analysis of anthocyanin and flavonol data. Heatmap of concentrations of 12 pigment compounds measured on 138 vines of the hybrid F₂ backcross families between (Actinidia eriantha x A. chinensis var. chinensis) and A. chinensis var. chinensis. The data displayed on a colour scale are the normalised (Z scores) log² values of the raw data. The dendrograms corresponding to rows (i.e., vines) and columns (i.e., compound variables) have been constructed by hierarchical clustering. The compounds measured were the anthocyanins delphinidin 3-O-(xylosyl)galactoside, delphinidin 3-O-galactoside, cyanidin 3-O-(xylosyl)galactoside, cyanidin 3-O-galactoside, cyanidin 3-O-glucoside and three unidentified anthocyanins, and the flavonols quercetin-rutinoside, quercetin-glucoside, kaemferol-glucoside and kaemferol-rutinoside.
