Fig. 1 From:Unlocking the relationships among population structure, plant architecture, growing season, and environmental adaptation in Henan wheat cultivars Population structure of association mapping panel of wheat accessions from Henan province based on the iSelect 90 K SNP genotyping.aMembership coefficient (Q-value) where each horizontal line represents ranged wheat cultivars (X-axis) and the accessions were partitioned into four subpopulations. Y axis represented the percentage of shared alleles between paired lines.bThe plot of the scaled mean logarithm of the probability of data likelihood [LnP (D)] (Y-axis) and delta K (ΔK) with K (X-axis) allowed ranging from 2 to 10.cPlot of the first two principal components illustrated four subpopulations which assigned in STRUCTURE result.dNeighbor-joining phylogenetic tree of 96 wheat cultivars. Colors of branches in the tree indicate matching the population inferior by Sp1 to Sp4 Back to article page
