Formatted data of 326 genotyped individuals including industry suspected variety, discriminant analysis of principal components (DAPC) assigned variety, assigned affinity propagation groups, silhouette scores, and genotype data. 

This datasets also include DAPC analysis of 159 genotypes indicating the cluster’s composition from K = 2 until K = 7 a) Bayesian information criterion (BIC) plot b) DAPC scatterplot - The eigenvalues and variance of each PC are found within parentheses on each axis. Individuals are represented as dots c) Genomic composition plot - Each thin vertical line in the bar plot represents one individual and each colour represents one inferred ancestral population. The length of each colour in a vertical bar represents the proportion of that individual’s ancestry that is derived from the inferred ancestral population corresponding to that colour. The same colour in different individuals indicates that they belong to the same cluster, indicating admixture.
