Genetic structure of the core collection. Two-dimension DAPC (Discriminant Analysis of Principal Component) scatter plot based on 21 SSRs (a) and on 7132 SNPs (c). Scatterplots represent the distribution of individuals along the first two linear discriminants. Population structure of the collection using the program STRUCTURE based on 21 SSRs (b) and on 7132 SNPs (d). Plots of mean probability of ΔK as calculated by Evanno et al. [41] to detect greatest likelihood of K. Barplots represent the average estimated membership probability of an individual to belong to a specific cluster (indicated by specific color) generated with the DISTRUCT software based on the Q-matrix consensus using the CLUMPP software
