  1. F2 plants were evaluated for RYMV resistance based on symptom observations. The phenotype is indicated with R for resistant plants and S for susceptible ones. For populations derived from crosses with Og82 and Og431 susceptible accessions, the observed phenotypic segregation was compared to a 1R/3S segregation ratio, based on a binomial exact test. For these populations, genotyping on the CPR5–1 gene was generally performed on all plants with CAPS or dCAPS markers, except for the (Og133 x Og431) population for which genotyping was based on Sanger sequencing and only performed on a subset of 35 plants. The genotype is indicated as “rymv2-Rx” for plants homozygous for alleles rymv2-R2 to -R6, “Rymv1-S1” for plants homozygous for the Rymv1-S1 allele, and Htz for heterozygous plants. F2 plants derived from crosses with Tog7291 were not genotyped
