Extended Data Fig. 3: Analyses of population genetic structure of Asian rice based on 1121 rice landraces with mislabeled and admixed accessions indicated.

a. Neighbor-joining tree of 1121 rice landraces. Lines in colors represent six cultivar groups originally defined. The scale bar shows substitutions per site. b. Principal components of 1121 rice landraces. Dots in colors indicate six cultivar groups and those in grey indicate admixed accessions. c. ADMIXTURE plots for rice landraces. Two rice subspecies are indicated above the plots. Columns represent the landraces with the cultivar groups indicated below the plots.
