Molecular classification of Chinese M. sinensis germplasm.
a Population structure of Chinese M. sinensis germplasm. b Classification of Chinese M. sinensis germplasm based on neighbor-joining tree clustering analysis. Note: The colors of the branch is consistent with the colors of structure group in a (G1 = red, G2 = green, G3 = blue, G4 = yellow, and G5 = purple). The vertical bars represent each genotype while division of the bars shows the genome content based on the sub-population identity.

The original geographical distribution of 457 M. sinensis accessions showed on a partial Chinese map.
The colorful objects represent various subpopulations generated by population structure analysis. The two accessions from USA are not shown in this figure.
