In file Figure S2<b> </b>the two principal components explaining the greatest variation from a PCA of the genotypic information are plotted. File Table S1<b> </b>provides an overview of the paircross parents and their progeny populations used in this work. File Table S2 contains the barcode sequences used for the preparation of the GBS libraries. File Table S3<b> </b>contains gene annotations for all scaffolds found to be significantly associated with the response to anther culture. The File S1 contains genotypes and phenotypes of each individual.
