Boxplots of genotypic effects of the most significant KASP markers developed for each QTL identified through XP-GWAS of disease response of the USDA Citrullus collection after inoculation with Podosphaera xanthii race 2 W7. Association between the markers and disease response was tested using analysis of variance (ANOVA) with the aov function36 in R25. Homozygous resistant is labelled ‘A’ and homozygous susceptible is ‘B’. The number of accessions with each allele at the SNPs were: SNP CS2_31304458 A = 42 and B = 130; SNP CS4_1119489 A = 26 and B = 158; and SNP CS7_4873496 A = 23 and B = 162. Figure generated in R25.
