Rhinanthus major and R. minor are two annual plant species that are known to hybridize in nature and in which unilateral introgression is likely to occur. Here we used double-digest restriction site-associated DNA sequencing technology (ddRAD-seq) to detect 16,932 genome-wide SNPs in R. major and R. minor individuals from 9 populations. After screening these SNP markers across both species, we selected 1106 putative loci that contain diagnostic, species-specific SNPs, which can be used for assessing and monitoring hybridization and introgression between R. major and R. minor.
