= 25.0%). Kompetitive allele-specific PCR (KASP) assays were developed for both QTL and assessed against diverse germplasm. Our results indicate that KASP markers associated with R1 may be limited to materials that are pedigree-related to Zenith, whereas markers associated with sex may be transferable across populations. The high-density map, QTL, and associated KASP markers will enable selecting for sex and R1-mediated resistance in hop.
