Fig. 5

Principal coordinate analysis (PCoA) of 102 genotypes in the panel population for grain Fe and Zn content using 100 molecular markers. The dot numbers in the figure represent the serial number of the genotypes enlisted in Table 1. The numbers are coloured on the basis of (a) sub-populations obtained from structure analysis (SP1-green; SP2-blue; SP3-Pink; admix type-red) (b) grain Fe and Zn content (common high grain Fe and Zn content – red; common moderate grain Fe and Zn content – green)
