Fig. 10From: Characterizing the population structure and genetic diversity of maize breeding germplasm in Southwest China using genome-wide SNP markersPathway of population simplification from K = 6 to K = 2. Number following a group represents the group size. Red arrow represents the unique path from the initial population. Blue arrow represents the multiple major sources from the initial population. Dashed line arrow means a rare path from the last population. Mixed group are excluded for each K valueBack to article page
