Analysis of population structure and familial relatedness. ( A) Principal coordinate analysis of the 161 genotypes based on modified Rogers’ distances. Percentages in parentheses refer to the proportion of variance explained by the principal coordinate. ( B) Violin plot showing the density distribution of the first ten principal coordinates. Percentages on the x-axis refer to the proportion of variance explained by the respective principal coordinate. ( C) Histogram of the genetic similarities (simple matching coefficient) among all lines, winter types and spring types. Dashed lines indicate the population-specific means.
