Fig. 3From: Profiling and quantification of grain anthocyanins in purple pericarp × blue aleurone wheat crosses by high-performance thin-layer chromatography and densitometryPCA biplot of seven anthocyanin HPTLC peak heights of blue, purple and deep purple grained wheat genotypes. Peak numbers 2 to 8 correspond to the target zones at the following R f values: 0.28, 0.34, 0.37, 0.45, 0.49, 0.52 and 0.59, respectively. Genotype codes correspond to Table 2 in “Appendix 1”Back to article page
