Fig. 2. — Neighbor–Joining (NJ) analysis and principal component analysis (PCA) of Chinese green foxtail accessions. (A) Unrooted NJ tree of 288 green foxtail; every coloured branch represents one accession collected from the corresponding inferred subpopulation. (B) NJ tree of inferred subgroups based on Nei’s genetic distance; the bootstrap value (out of 1000) is indicated at the branch point. (C) Differentiation of genotypes from subpopulations according to the first principal component derived from diversity analysis of 69 SSR markers.
